2015-07-22doc: discourage use of uname -i and -p optionsPádraig Brady
* src/uname.c (usage): State that the non POSIX -i and -p options are non-portable. * doc/coreutils.texi (uname invocation): Mention the discrepancies even across GNU/Linux distros, and that the results should be used as informational only, rather than impacting any logic decisions. Fixes http://bugs.gnu.org/13001
2015-07-15tests: avoid test warning with perl >= 5.22Peter Bray
* doc/local.mk (sc-lower-case-var): Escape a literal left curly bracket, needed with perl >= 5.22 Fixes http://bugs.gnu.org/21060
2015-06-22doc: list numfmt in the main menu with "Numeric operations"Pádraig Brady
* doc/coreutils.texi (main menu): Add numfmt.
2015-06-21numfmt: support user specified output precisionPádraig Brady
* src/numfmt.c (usage): Update the --format description to indicate precision is allowed. (parse_format_string): Parse a precision specification like the standard printf does. (double_to_human): Honor the precision in --to mode. * tests/misc/numfmt.pl: New tests. * doc/coreutils.texi (numfmt invocation): Mention the new feature. * NEWS: Likewise.
2015-06-19numfmt: implement support for field rangesDylan Cali
* src/numfmt.c: Replace field handling code with logic that understands field range specifiers. Instead of processing a single field and printing line prefix/suffix around it, process each field in the line checking whether it has been included for conversion. If so convert and print, otherwise just print the unaltered field. (extract_fields): Removed. (skip_fields): Removed. (process_line): Gutted and heavily reworked. (process_suffixed_number): FIELD is now passed as an arg instead of using a global. (parse_field_arg): New function that parses field range specifiers. (next_field): New function that returns pointers to the next field in a line. (process_field): New function that wraps the field conversion logic (include_field): New function that checks whether a field should be converted (compare_field): New function used for field value comparisons in a gl_list. (free_field): New function used for freeing field values in a gl_list. Global variable FIELD removed. New global variable all_fields indicates whether all fields should be processed. New global variable all_fields_after stores the first field of a N- style range. New global variable all_fields_before stores the last field of a -M style range. New global variable field_list stores explicitly specified fields to process (N N,M or N-M style specifiers). (usage): Document newly supported field range specifiers. * bootstrap.conf: Include xlist and linked-list modules. numfmt now uses the gl_linked_list implementation to store the field ranges. * tests/misc/numfmt.pl: Add tests for 'cut style' field ranges. Adjust existing tests as partial output can occur before an error Remove test for the 'invalid' field -5.. this is now a valid range. * gnulib: update to avoid compiler warnings in linked-list. * NEWS: Mention the new feature.
2015-06-19numfmt: handle suffixes consistently with --{from,to}-unitPádraig Brady
* src/numfmt.c (unit_to_umax): Support SI (power of 10) suffixes with the --from-unit and --to-unit options. Treat suffixes like is done with --from=auto, which for example will change the meaning of --to-unit=G to that of --to-unit=Gi. The suffix support was previously undocumented and it's better to avoid the traditional coreutils suffix handling in numfmt by default. * doc/coreutils.texi: Document the new behavior. Also fix a typo mentioning {from,to}=units=. * tests/misc/numfmt.pl: Adjust accordingly. * NEWS: Mention the change in behavior.
2015-05-13timeout: with --foreground don't send SIGCONTPádraig Brady
* src/timeout.c (cleanup): Don't send SIGCONT to the monitored program when --foreground is specified, as it's generally not needed for foreground programs, and can cause intermittent signal delivery issues with monitors like GDB for example. * doc/coreutils.texi (timeout invocation): Mention that SIGCONT is not sent with --foreground. * NEWS: Mention the behavior change.
2015-05-13split: auto set suffix len for --numeric-suffixes=<N --number=NPádraig Brady
Supporting `split --numeric-suffixes=1 -n100` for example. * doc/coreutils.texi (split invocation): Mention the two use cases for the FROM parameter, and the consequences on the suffix length determination. * src/split.c (set_suffix_length): Use the --numeric-suffixes FROM parameter in the suffix width calculation, when it's less than the number of files specified in --number. * tests/split/suffix-auto-length.sh: Add test cases. Fixes http://bugs.gnu.org/20511
2015-05-13doc: clarify the operation of wc -LAssaf Gordon
* src/wc.c (usage): State that it calculates display width. * doc/coreutils.texi (wc invocation): Detail the distinct items used to determine the display width.
2015-04-23doc: fix grammar issue in truncate infoMichael Witten
* doc/coreutils.texi (truncate invocation): The word 'their' is incorrect; 'each file' is the antecedent, and is singular, so 'its' is the correct pronoun.
2015-04-13doc: clarify how cp behaves with default ACLsAndreas Gruenbacher
* doc/coreutils.texi (cp invocation): Mention that when copying files without preserving permissions, the umask or a default ACL affect the mode of new files. * THANKS.in: Remove committer. Related to http://bugs.gnu.org/8527
2015-04-09doc: correct pluralization for mkfifo and mknodMitchel Humpherys
* doc/coreutils.texi: `mkfifo' and `mknod' use the optContext macro which adds a description for the SELinux security context in addition to the single option already described in each case. The result in both cases is two options being introduced as `option' (singular). Fix this by introducing them as `options' (plural).
2015-03-29doc: move numfmt info to the 'Numeric operations' sectionPádraig Brady
* doc/coreutils.texi: Move numfmt info to this section, as numfmt functionality aligns more with seq and factor, than fmt and pr etc.
2015-03-27nohup: clarify stdin redirectionPaul Eggert
Problem reported by Isaac Schwabacher in: http://bugs.gnu.org/20214 * doc/coreutils.texi (nohup invocation): Clarify that when nohup's stdin gets redirected, it's unreadable. * doc/coreutils.texi (nohup invocation): * src/nohup.c (usage): Don't promise /dev/null.
2015-03-04tee: generalize the --write-error option to --output-errorPádraig Brady
Adjust commit v8.23-140-gfdd6ebf to add the --output-error option instead of --write-error, and treat open() errors like write() errors. * doc/coreutils.texi (tee invocation): s/write-error/output-error/. * src/tee.c (main): Exit on open() error if appropriate. * tests/misc/tee.sh: Add a case to test open() errors. * NEWS: Adjust for the more general output error behavior. Suggested by Bernhard Voelker.
2015-02-24tee: add --write-error to control handling of closed pipesPádraig Brady
tee is very often used with pipes and this gives better control when writing to them. There are 3 classes of file descriptors that tee can write to: files(1), pipes(2), and early close pipes(3). Handling write errors to 1 & 2 is supported at present with the caveat that failure writing to any pipe will terminate tee immediately. Handling write errors to type 3 is not currently supported. To improve the supported combinations we add these options: --write-error=warn Warn if error writing any output including pipes. Allows continued writing to still open files/pipes. Exit status is failure if any output had error. --write-error=warn-nopipe, -p Warn if error writing any output except pipes. Allows continued writing to still open files/pipes. Exit status is failure if any non pipe output had error. --write-error=exit Exit if error writing any output including pipes. --write-error=exit-nopipe Exit if error writing any output except pipes. Use the "nopipe" variants when files are of types 1 and 3, otherwise use the standard variants with types 1 and 2. A caveat with the above scheme is that a combination of pipe types (2 & 3) is not supported robustly. I.e. if you use the "nopipe" variants when using both type 2 and 3 pipes, then any "real" errors on type 2 pipes will not be diagnosed. Note also a general issue with type 3 pipes that are not on tee's stdout, is that shell constructs don't allow to distinguish early close from real failures. For example `tee >(head -n1) | grep -m1 ..` can't distinguish between an error or an early close in "head" pipe, while the fail on the grep part of the pipe is distinguished independently from the resulting pipe errors. This is a general issue with the >() construct, rather than with tee itself. * NEWS: Mention the new feature. * doc/coreutils.texi (tee invocation): Describe the new option. * src/tee.c (usage): Likewise. (main): With --write-error ignore SIGPIPE, and handle the various exit, diagnostics combinations. * tests/misc/tee.sh: Tess all the new options. Fixes http://bugs.gnu.org/11540
2015-02-20tee: treat '-' operand as file name as mandated by POSIXBernhard Voelker
Since v5.2.1-1247-g8dafbe5, tee(1) treated '-' as stdout while POSIX explicitly requires to treat this as a file name. Revert this change, as the interleaved output - due to sending another copy of input to stdout - is not considered to be useful. Discussed in http://lists.gnu.org/archive/html/coreutils/2015-02/msg00085.html * src/tee.c (tee_files): Remove the special handling for "-" operands. (usage): Remove the corresponding sentence. * doc/coreutils.texi (common options): Remove the "tee -" example. (tee invocation): Document that tee(1) now treats "-" as a file name. * tests/misc/tee.sh: Add a test case for "tee -". While at it, re-indent the above multi-argument processing case and extend that to 13 operands, as POSIX mandates that, too. * tests/misc/tee-dash.sh: Remove now-obsolete test. * tests/local.mk (all_tests): Remove the above test. * NEWS (Changes in behavior): Mention the change.
2015-02-11build: update to latest gnulibPádraig Brady
This includes a change to require --with-libmount to be used with configure, due to the many libmount dependencies. * bootstrap: Sync with gnulib to exit early on gnulib-tool error. * gl/lib/tempname.c.diff: Adjust for gnulib changes. * gl/lib/tempname.h.diff: Likewise. * gl/modules/tempname: Likewise. * doc/.gitignore: Add new gendocs_template_min gnulib script.
2015-02-11doc: give an example of using a seed for random operationsPádraig Brady
* doc/coreutils.texi (Random sources): Give an example using openssl, generating a reproducible arbitrary amount of randomly distributed data, given a seed value.
2015-01-31doc,maint: fix use of "i.e." in documentation and commentsBernhard Voelker
To align with all other places (and correct grammar), change all upper-case "I.E." to "I.e.". Furthermore, ensure that "i.e." is followed by a comma. Finally, ensure to use a double-space before "I.e.," at the beginning of a sentence. The following was used to change all offending uses (apart from old ChangeLog files): $ git grep -liF 'i.e.' \ | xargs sed -i \ -e 's/I\.E\./I.e./g' \ -e 's/\. \(I\.e\.\)/. \1/g' \ -e 's/\([Ii]\.e\.\)\( \)/\1,\2/g' \ -e 's/\([Ii]\.e\.\)$/\1,/g' * cfg.mk (sc_prohibit_uppercase_id_est): Add new rule. (sc_ensure_double_space_after_dot_before_id_est): Likewise. (sc_ensure_comma_after_id_est): Likewise. (old_NEWS_hash): Refresh hash via "make update-NEWS-hash". * NEWS: Change use of "id est" abbreviation via the above command. * README: Likewise. * README-prereq: Likewise. * doc/coreutils.texi: Likewise. * gl/lib/rand-isaac.c: Likewise. * gl/lib/tempname.c.diff: Likewise. * man/stdbuf.x: Likewise. * src/cat.c: Likewise. * src/copy.c: Likewise. * src/copy.h: Likewise. * src/cp.c: Likewise. * src/cut.c: Likewise. * src/dd.c: Likewise. * src/df.c: Likewise. * src/fiemap.h: Likewise. * src/longlong.h: Likewise. * src/ls.c: Likewise. * src/numfmt.c: Likewise. * src/pr.c: Likewise. * src/shred.c: Likewise. * src/shuf.c: Likewise. * src/split.c: Likewise. * tests/Coreutils.pm: Likewise. * tests/df/df-symlink.sh: Likewise. * tests/df/skip-rootfs.sh: Likewise. * tests/init.sh: Likewise. * tests/ls/color-norm.sh: Likewise. * tests/misc/basename.pl: Likewise. * tests/misc/ls-misc.pl: Likewise. * tests/misc/md5sum-bsd.sh: Likewise. * tests/misc/shred-exact.sh: Likewise. * tests/misc/sort.pl: Likewise. * tests/misc/stdbuf.sh: Likewise. * tests/misc/tac-continue.sh: Likewise. * tests/rm/r-root.sh: Likewise. * tests/tail-2/symlink.sh: Likewise.
2015-01-29doc: clarify the output format for the *sum utilitiesPádraig Brady
* src/md5sum.c (usage): Detail the reasons for the default double space between checksum and file name. * doc/coreutils.texi (md5sum invocation): Likewise. Explicitly mention the 3 formats that --check supports. Fixes http://bugs.gnu.org/19725
2015-01-28sync: support syncing specified argumentsGiuseppe Scrivano
* m4/jm-macros.m4 (coreutils_MACROS): Check for syncfs(). * man/sync.x: Add references to syncfs, fsync and fdatasync. * doc/coreutils.texi (sync invocation): Document the new feature. * src/sync.c: Include "quote.h". (AUTHORS): Include myself. (MODE_FILE, MODE_DATA, MODE_FILE_SYSTEM, MODE_SYNC): New enum values. (long_options): Define. (sync_arg): New function. (usage): Describe that arguments are now accepted. (main): Add arguments parsing and add support for fsync(2), fdatasync(2) and syncfs(2). * tests/misc/sync.sh: New (and only) test for sync. * tests/local.mk: Reference the new test. * AUTHORS: Add myself to sync's authors. * NEWS: Mention the new feature.
2015-01-24stty: only print supported options for combined optionsPádraig Brady
* src/stty.c (usage): Don't reference unsupported options, in the combined options descriptions. * doc/coreutils.texi (stty invocation): Adjust for the new order of the 'sane' and 'raw' combined options. Also add -iutf8 to the 'sane' list.
2015-01-24stty: document the 'status' character where supportedPádraig Brady
* src/stty.c (usage): On systems that support this setting (BSD), display 'status' in the list of adjustable special characters. * doc/coreutils.texi (stty invocation): Mention the option, and that it's not currently supported on Linux.
2015-01-24stty: document the 'discard' character settingPádraig Brady
The equivalent of this is 'flush', but that was never documented as an option (though was output with stty -a). Therefore use the more descriptive name, also generally used on BSD systems. Note even though this setting seems ineffective on Linux, supporting the setting is useful to allow terminal programs to receive the default ^O character code. * doc/coreutils.texi (stty invocation): Document the 'discard' option. * src/stty.c (struct control_info): Add 'discard'; same as 'flush'. (display_all): Show 'discard' rather than 'flush' char. (display_changed): Likewise. (usage): Document the 'discard' option.
2015-01-24stty: add support for extproc/LINEMODEPádraig Brady
Add support for the "extproc" option which is well described at: http://lists.gnu.org/archive/html/bug-readline/2011-01/msg00004.html * src/stty.c (usage): Describe the extproc option if either the Linux EXTPROC local option is defined, or the equivalent BSD TIOCEXT ioctl is defined. (main): Make the separate ioctl call for extproc on BSD. * doc/coreutils.texi (stty invocation): Describe the option, and reference the related RFC 1116. * NEWS: Mention the new feature.
2015-01-19split: new -t option to select record separatorAssaf Gordon
* src/split.c (eolchar): A new variable to hold the separator character (unibyte for now). This is reference throughout rather than hardcoding '\n'. (usage): Describe the new --separator option, and mention records along with lines so there is no ambiguity that all options treat lines and records equivalently. (main): Have -t update eolchar, or default to '\n'. * tests/split/record-sep.sh: New test case. * tests/local.mk: Reference the new test. * doc/coreutils.texi (split invocation): Document the new option. Adjust --lines, --line-bytes, --number=[lr]/... to mention they pertain to records if --separator is specified. * NEWS: Mention the new feature.
2015-01-19doc: clarify that du operands are interdependentPádraig Brady
Following on from http://bugs.gnu.org/17546 make it more obvious that du may elide specified operands to avoid double counting in the set. * src/du.c (usage): Specify that du operates on the set of operands, rather than each independently. * doc/coreutils.texi (du invocation): Likewise. Also state that the number of entries printed may change due to the order specified. Currently, deeper items specified earlier will result in them being displayed, but don't mention that implementation detail in the documentation. * THANKS.in: Add reporter. Reported by Stephen Shirley
2015-01-01maint: update all copyright year number rangesPádraig Brady
Run "make update-copyright" and then... * tests/sample-test: Adjust to use the single most recent year. * tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message, so that year is updated automatically in future.
2014-12-26doc: update the URL referencing SI prefixesPádraig Brady
Identified at https://www.gnu.org/software/gnun/linc/linc.html * doc/coreutils.texi (Block size): Fix the stale link.
2014-11-24df: only suppress remote mounts of separate exports with --totalPádraig Brady
* src/df.c (filter_mount_list): Separate remote locations are generally explicitly mounted, so list each even if they share the same remote device and thus storage. However with --total keep the suppression to give a more accurate value for the total storage available. (usage): Expand on the new implications of --total and move it in the options list according to alphabetic order. doc/coreutils.texi (df invocation): Mention that --total impacts on deduplication of remote file systems and also move location according to alphabetic order. * tests/df/skip-duplicates.sh: Add remote test cases. * NEWS: Mention the change in behavior. Reported in http://bugs.debian.org/737399 Reported in http://bugzilla.redhat.com/920806 Reported in http://bugzilla.opensuse.org/866010 Reported in http://bugzilla.opensuse.org/901905
2014-11-21doc: mention how to avoid newlines impacting ls -1Pádraig Brady
* src/ls.c (usage): Mention the -b and -q options in the -1 description. * doc/coreutils.texi (ls invocation): Likewise.
2014-10-27doc: mention that df -a includes duplicate file systemsPádraig Brady
* src/df.c (usage): Mention that duplicate file systems are shown with this option, not just dummy file systems. * doc/coreutils.texi (df invocation): For the --all option, expand on the class of normally suppressed mount entries that it includes. Reported in http://bugs.debian.org/737399
2014-10-04doc: document stat's output with the --terse optionBernhard Voelker
* doc/coreutils.texi (stat invocation): Add a paragraph documenting stat's output format when the --terse option is specified, both in normal and in --file-system mode. Reported by Dan Jacobson <jidanni@jidanni.org> in http://bugs.gnu.org/18624
2014-09-30dd: new status=progress level to print stats periodicallyFederico Simoncelli
* src/dd.c: Report the transfer progress every second when the new status=progress level is used. Adjust the handling and description of the status= option so that they're treated as mutually exclusive levels, rather than flags with implicit precedence. * doc/coreutils.texi (dd invocation): Document the new progress status level. Reference the new level in the description of SIGUSR1. * tests/dd/stats.sh: Add new test for status=progress. * tests/dd/misc.sh: Change so status=none only takes precedence if it's the last level specified. * NEWS: Mention the feature.
2014-09-30dd: use more robust SIGUSR1 handlingPádraig Brady
* src/dd.c (ifd_reopen): A new wrapper to ensure we don't exit upon receiving a SIGUSR1 in a blocking open() on a fifo for example. (iftruncate): Likewise for ftruncate(). (iread): Process signals also after a short read. (install_signal_handlers): Install SIGINFO/SIGUSR1 handler even if set to SIG_IGN, as this is what the parent can easily set from a shell script that can send SIGUSR1 without the possiblity of inadvertently killing the dd process. * doc/coreutils.texi (dd invocation): Improve the example to show robust usage wrt signal races and short reads. * tests/dd/stats.sh: A new test for various signal races. * tests/local.mk: Reference the new test. * NEWS: Mention the fix.
2014-09-19doc: ensure the correct texinfo nodes are referenced in --helpPádraig Brady
* src/system.h (emit_ancillary_info): For commands that don't have a 1:1 mapping with the texinfo node names, provide a mapping to the correct node. * doc/coreutils.texi: Add some extra cross references noticed while checking this. Fixes http://bugs.debian.org/762092
2014-09-08doc: rename "coreutils invocation" to "Multi-call invocation"Paul Eggert
This supports longstanding shell commands like 'info coreutils "touch invocation"'. Problem reported by Vincent Lefevre via Bob Proulx in: http://bugs.gnu.org/18428 * doc/coreutils.texi (Multi-call invocation): Rename from "coreutils invocation".
2014-09-08doc: mention which commands are optionalPaul Eggert
* doc/coreutils.texi (coreutils invocation, df invocation) (stty invocation, whoami invocation, nproc invocation) (arch invocation, hostname invocation, hostid invocation) (uptime invocation, chroot invocation, nice invocation) (stdbuf invocation): Document that the command is installed optionally.
2014-09-07doc: fix typosBernhard Voelker
* doc/coreutils.texi: Fix normal typos: s/pseudorandom/pseudo-random/; s/behaviour/behavior/; s/linux-based/Linux-based/; s/nonnegative/non-negative/. Fix IEC's long name: s/Electronical/Electrotechnical/. Wrap 'getopt' into the @code{} macro. Fix a grammatical error (from myself): s/splitted/split/.
2014-09-03doc: spell "indeterminate" correctlyPaul Eggert
* doc/coreutils.texi (timeout invocation): Fix misspelling. Reported by Yureruchihirosan via OKANO Takayoshi in: http://bugs.gnu.org/18394
2014-08-21doc: clarify that duplicate NFS mounts are skipped by dfFridolin Pokorny
* doc/coreutils.texi (df invocation): Add a sentence that eliding duplicate entries for the same file system is not limited to bind mounts, but also happens for remote file systems like NFS.
2014-08-01chroot: perform chdir("/") again unless new --skip-chdir is specifiedBernhard Voelker
Since commit v8.22-94-g99960ee, chroot(1) skips the chroot(2) syscall for "/" arguments (and synonyms). The problem is that it also skips the following chdir("/") call in that case. The latter breaks existing scripts which expect "/" to be the working directory inside the chroot. While the first part of the change - i.e., skipping chroot("/") - is okay for consistency with systems where it might succeed for a non-root user, the second part might be malicious, e.g. cd /home/user && chroot '/' bin/foo In the "best" case, chroot(1) could not execute 'bin/foo' with ENOENT, but in the worst case, chroot(1) would execute '/home/user/bin/foo' in the case that exists - instead of '/bin/foo'. Revert that second part of the patch, i.e., perform the chdir("/) in the common case again - unless the new --skip-chdir option is specified. Restrict this new option to the case of "/" arguments. * src/chroot.c (SKIP_CHDIR): Add enum. (long_opts): Add entry for the new --skip-chdir option. (usage): Add --skip-chdir option, and while at it, move the other to options into alphabetical order. (main): Accept the above new option, allowing it only in the case when NEWROOT is the old "/". Move down the chdir() call after the if-clause to ensure it is run in any case - unless --skip-chdir is specified. Add a 'newroot' variable for the new root directory as it is used in a couple of places now. * tests/misc/chroot-fail.sh: Invert the last tests which check the working directory of the execvp()ed program when a "/"-like argument was passed: now expect it to be "/" - unless --skip-chdir is given. * doc/coreutils.texi (chroot invocation): Document the new option. Document that chroot(1) usually calls chdir("/") unless the new --skip-chdir option is specified. Sort options. * NEWS (Changes in behavior): Mention the fix. (New features): Mention the new option. * init.cfg (nonroot_has_perm_): Add chroot's new --skip-chdir option. * tests/cp/preserve-gid.sh (t1): Likewise. * tests/cp/special-bits.sh: Likewise. * tests/id/setgid.sh: Likewise. * tests/misc/truncate-owned-by-other.sh: Likewise. * tests/mv/sticky-to-xpart.sh: Likewise. * tests/rm/fail-2eperm.sh: Likewise. * tests/rm/no-give-up.sh: Likewise. * tests/touch/now-owned-by-other.sh: Likewise. Reported by Andreas Schwab in http://bugs.gnu.org/18062

* doc/coreutils.texi (Floating point): Document handling of "inf", "infinity", "NaN", and so on.
2014-07-13build: support building all tools in a single binaryAlex Deymo
Add the --enable-single-binary option to the configure file. When enabled, this option builds a single binary file containing the selected tools. Which tool gets executed depends on the value of argv[0] which can be set implicitly through symlinks to the single program. This setup reduces significantly the size of a complete coreutils install, since code from lib/libcoreutils.a is not duplicated in every one of the more than 100 binaries. Runtime overhead is increased due to more dynamic libraries being loaded, and extra initialization being performed for all utils. Also initially a larger binary is loaded from storage, though this is usually alleviated due to caching and lazy mmaping of unused blocks, and in fact the single binary should have better caching characteristics. Comparing the size of the individual versus single binary on x86_64: $ cd src $ size coreutils $ size -t $(../build-aux/gen-lists-of-programs.sh --list-progs | grep -Ev '(coreutils|libstdbuf)') | tail -n1 text data bss dec hex filename 1097416 5388 88432 1191236 122d44 src/coreutils 4901010 124964 163768 5189742 4f306e (TOTALS) Storage requirements are reduced similarly: $ cd src $ du -h coreutils $ du -ch $(../build-aux/gen-lists-of-programs.sh --list-progs | grep -Ev '(coreutils|libstdbuf)') | tail -n1 1.2M coreutils 5.3M total When installing, the makefile will create either symlinks or shebangs based on the --enable-single-binary setting, for each configured tool. In this way, all the tools are still callable individually, but they are all implemented by the same "coreutils" binary installed on the same directory. * .gitignore: Add new generated files. * Makefile.am: New rules to generate build-aux/gen-single-binary.sh and install symlinks. * NEWS: Mention the new feature. * README: Add "coreutils" to the list of utils. * bootstrap.conf: Regenerate src/single-binary.mk * build-aux/gen-lists-of-programs.sh: New --list-progs option. * build-aux/gen-single-binary.sh: Regenerate * configure.ac: New --enable-single-binary option and other variables. Disallow --enable-single-binary=symlinks with --program-prefix et. al. * man/coreutils.x: Manpage hook. * man/local.mk: Add manpage hook and fix dependencies. * src/coreutils.c: Multicall implementation. * src/local.mk: New rules for the single binary option. * tests/local.mk: Add $single_binary_progs to support require_built_() from init.cfg * tests/misc/env.sh: Avoid the use of symlink to echo. * tests/misc/help-version.sh: Add exception for coreutils. * tests/install/basic-1.sh: Really avoid using ginstall strip functionality if there is an issue with the independent strip command. * src/kill.c: Changes to call exit() in main. * src/readlink.c: Likewise. * src/shuf.c: Likewise. * src/timeout.c: Likewise. * src/truncate.c: Likewise.
2014-07-02pwd: revert default mode back to -PPádraig Brady
Revert commit v8.22-131-g3e89d5b as even though POSIX states that the default mode should be -L, common practice for stand-alone pwd implementations is to default to -P. * src/pwd.c (usage): Retain mention of the default mode of operation. Suggested by Bob Proulx
2014-06-30pwd: assume -L mode by default, as per POSIXPádraig Brady
* src/pwd.c (main): Adjust default mode to be "logical" and independent of the POSIXLY_CORRECT env var. (usage): Mention the default mode of operation. * doc/coreutils.texi (pwd invocation): Adjust accordingly. * tests/misc/pwd-option.sh: Likewise. * NEWS: Mention the change in behavior.
