2015-11-21doc: give a tee example for combining process substitution outputsPádraig Brady
This can be useful if you want to further process data from process substitutions. For example: datagen | tee >(md5sum --tag) > >(sha256sum --tag) | sort * doc/coreutils.texi (tee invocation): Mention that -p is useful with pipes that may not consume all data. Add an example, similar to the one above. * THANKS.in: Add Jirka Hladky.
2015-11-04ls: default to --quoting=shell-escape for output to terminalPádraig Brady
* src/ls.c (decode_switches): Set "shell-escape" if isatty(). * doc/coreutils.texi (ls invocation): Update the defaults description. * NEWS: Mention the change in behavior. It should not have backwards compat issues, but mentioning here just in case.
2015-11-04printf: support the %q format to quote for shellPádraig Brady

2015-11-02doc: fix texinfo for short options taking a parameterPádraig Brady
* doc/coreutils.texi: (tail invocation): Add missing -s, along with the existing --sleep-interval description. (csplit invocation): s/--suffix/--suffix-format/. (head invocation): Use same variable (COUNT) for -n and --head-count. (seq invocation): Add opindex items for all options. (ptx invocation): Likewise. Fix typo s/--flac-truncation/--flag-truncation/. (touch invocation): State explicitly that -d takes a parameter, which also indicates that an '=' is not to be used for the short option syntax. (ls invocation): Likewise for the -w option. Fixes http://bugs.gnu.org/21809
2015-10-28doc: clarify iso-8601 formats used by ls and duPádraig Brady
* doc/coreutils.texi (du invocation): Remove 'like' from mentions of ISO-8601 as the components are individually conformant. (ls invocation): Likewise, except for --time-style=iso for recent files, where the MM-DD component is not a valid ISO-8601 timestamp.
2015-10-27date: use extended format timezone for --iso-8601Pádraig Brady
* src/date.c (main): Use %:z rather than %z with --iso-8601 as the standard states to consistently use extended format. Note either format can be parsed by date. * tests/misc/date.pl: Adjust accordingly. * doc/coreutils.texi (du invocation): Clarify that "iso" time styles are only similar to ISO-8601. (ls invocation): Likewise. (date invocation): Adjust the comment stating that only --rfc-3339 output can be parsed by date(1). * NEWS: Mention the change in behavior. Reported at http://bugs.debian.org/799479
2015-10-21ls: allow -w0 to mean no limit on line lengthPádraig Brady
* src/ls.c (print_with_separator): Renamed from print_with_commas, and parameterized to accept the separator to print. Also fix an edge case where '\n' not printed when the POS variable overflows SIZE_MAX. (print_current_files): Degenerate -x and -C to using the cheaper print_with_separator() in the -w0 case. * doc/coreutils.texi (ls invocation): Document the new feature. * tests/ls/w-option.sh: A new test. * tests/local.mk: Reference the new test. * NEWS: Mention the improvement. Fixes http://bugs.gnu.org/21325
2015-10-19factor: remove unreachable SQUFOF code at compile timePádraig Brady
It was a little confusing as to whether the SQUFOF algorithm was enabled, and in fact there were no options available to enable it. Therefore clarify the 3 configurable behaviors for the code to 3 defines at the top of the program, and only include the SQUFOF code if enabled at compile time. $ size src/factor-before text data bss 93997 1412 2504 $ size src/factor-after text data bss 87885 1404 2504 * src/factor.c: Only include the SQUFOF factor code when enabled via the USE_SQUFOF define. * doc/coreutils.texi (factor invocation): Update note about factor limits, as we can factor 128 bit numbers without GMP.
2015-10-16doc: remove obsolete performance commentPaul Eggert
sha512sum can be faster than sha256sum. E.g., ‘dd if=/dev/zero bs=1024k count=1024 | time sha256sum’ reports 8.16 user CPU seconds on my host, whereas sha512sum consumes 5.45 seconds (Fedora x86-64 on an AMD Phenom II X4 910e). Although sha512sum is still considerably slower on x86, a good chunk of uses are on 64-bit hosts and anyway there’s little point to scaring people away from sha512sum nowadays. * doc/coreutils.texi (sha2 utilities): Remove obsolete comment.
2015-09-17shred: don’t document -NUMBER optionPaul Eggert
The -NUMBER option was removed from ‘shred’ in 1999, but the manual wasn’t updated to match. Problem reported by Nick Rose in: http://bugs.gnu.org/21502 * doc/coreutils.texi (shred invocation): Remove documentation for -NUMBER option.
2015-09-03base32: A new program similar to base64Pádraig Brady
Suggested in https://bugzilla.redhat.com/1250113 * AUTHORS: Add base32. * THANKS.in: Add suggester. * README: Reference the new program. * NEWS: Mention the new program. * src/.gitignore: Ignore the new binary. * bootstrap.conf: Reference the gnulib base32 module. * build-aux/gen-lists-of-programs.sh: Add base32. * man/base32.x: A new template. * man/.gitignore: Ignore the new man page. * man/local.mk: Reference the new man page. * doc/coreutils.texi (base32 invocation): Document the new command. * src/local.mk: Adjust to build base32 based on base64.c. * src/base64.c: Parameterize to use the correct headers, functions and buffer sizes, depending on which binary is being built. * tests/misc/base64.pl: Adjust to test both base32 and base64. * tests/misc/tty-eof.pl: Add base32 as a program that accepts input on stdin without any options specified. * scripts/git-hooks/commit-msg: Add base32 to the template.
2015-08-27doc: clarify where ambiguous if short options take no paramPádraig Brady
* doc/coreutils.texi (split invocation): Clarify that -d takes no param. (uniq invocation): Likewise for -D. (shred invocation): Likewise for -u. (tee invocation): Likewise for -p.
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
2015-06-22doc: 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.
2015-02-11doc: 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.

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.
