MMDDhhmm file" must be treated like "touch MMDDhhmm file" when
conforming to pre-2001 POSIX.
|
|
"sort -y abc" is like "sort abc" whereas "sort -y 100" is like
plain "sort".

(COMMON_SHORT_OPTIONS): Add -B, -D, -e, -F, -H, -I, -L, -O, -s, -X.
(long_options, main): --strings is now -S, not -s.
(usage): Reflect the usage changes.
(parse_old_offset): Do not issue a diagnostic on failure;
callers now do this as necessary.
(main): Support POSIX syntax. Remove unused case 0 from getopt_long.
Add support for new short options (many undocumented) for
compatibility with FreeBSD. Remove FIXME for -s; it's now
POSIX-compatible. Default format is now oS, not o2.
|
|
|
|
(main): Use STDIN_FILENO, not 0.
Simplify option-parsing code a tad.
|
|
(main): Fix some bugs in handling invalid option-combinations
like "stty -F".

it from ever being nonzero. Reported by Pozsar Balazs in:

(human_fstype): Add ramfs, squashfs, sysfs.

(human_fstype): Return char const *, not char *.
Simplify internals a bit, and avoid casts.
|
|
(bit_count): Remove. All uses changed to....
(multiple_bits_set): New function.
(scanargs): Use it, and check separately for each set of
incompatible options, to improve diagnostics.
(MX): Remove.
(apply_translations): Move checks for incompatible options
to scanargs, so that they're done consistently.
|
|
(write_error, xputchar): New functions.
(paste_parallel): Use correct errno value after input error.
(paste_parallel, paste_serial): Report errno value after output error.
|
|
|
|
it's not portable C to assume FILE is a complete type.
(paste_parallel): Use null instead of ENDLIST, and an explicit
boolean instead of CLOSED.
|
|
(parse_tab_stop): Renamed from parse_tabstop. All uses changed.
(validate_tab_stop): Renamed from validate_tabstop. All uses changed.
(next_file, main): Check fclose against 0, not EOF.
(unexpand): Remove unnecessary casts.
Add another loop nesting level, for lines, so that per-line variables
are initialized cleanly.
Revamp tab checking. Check for write error immediately, rather
than just once at the end of the program.
(TAB_STOP_SENTINEL): Remove.
(tab_size): Now size_t, not uintmax_t, since we need to store
the sequences of blanks.
(max_column_width): New var.
(usage): Say "blank" where POSIX requires this.
(add_tab_stop): Calculate maximum column width.
(unexpand): Store the pending blanks, instead of merely counting them.
Follow POSIX's rules about -a requiring two blanks before a tab stop.
Get rid of internal label and goto.
|
|
(usage): -i does not convert tabs after non-tabs.
(add_tab_stop): Renamed from add_tabstop. All uses changed.
(parse_tab_stop): Renamed from parse_tabstop. All uses changed.
(validate_tab_stop): Renamed from validate_tabstop. All uses changed.
(next_file, main): Check fclose against 0, not EOF.
(expand): Remove unnecessary casts.
Add another loop nesting level, for lines, so that per-line variables
are initialized cleanly.
Revamp tab checking. Check for write error immediately, rather
than just once at the end of the program.

(main): Do not set user name to the empty string if the group
name is null.
|
|
without using "to OWNERSHIP" phrase.
|
|
through a pointer. Treat "chgrp '' file" as a no-op change,
as FreeBSD does.
(main): Set chopt.group_name to NULL if the group is the empty
string.

--target-directory support at 2004-06-25.
|
|
a destination with link count greater than one. This is so
that commands like "cp -a" don't get confused when copying into
a destination that already contains many hard links.
|
|
to a file named "-".
|
|
A null file arg means standard output.
(main): "-o -" means to write to a file named "-",
not to standard output.

bugs introduced on 2004-07-29.
|
|
(can_mode): Make variable local.
|
|
and not readable. Prefer write access, since this should work
better with fdatasync.
|
|
|
|
(main): Remove now-obsolete initialization of xalloc_fail_func.
|
|
|
|
Do not define, to avoid annoying compiler messages on QNX 6.3.
|
|
|
|
|
|
Define to a concatenation of string literals, not to an expression;
needed for concatenation contexts.
(INTMAX_MAX, INTMAX_MIN): New macros.
|
|
unsigned long; this isn't true for st_ino on Solaris 9.
|

whether to include files. Include <sys/param.h> if
HAVE_SYS_PARAM_H (not HAVE_SYSCTL).
(main) [defined __POWERPC__]: Add a kludge to work around a
Mac OS X bug, so that uname -p defaults to "powerpc" if
sysctl ((int[]) {CTL_HW, HW_MACHINE_ARCH}, 2, buffer, &bufsize, 0, 0)
fails. Problem reported by Petter Reinholdtsen in:

(print_lines, print_words, print_chars, print_bytes, print_linelength,
have_read_stdin, wc, wc_file, main):
Use bool for booleans.
(exit_status): Remove.
(wc, wc_file): Return bool status. All callers changed.
|
|
main): Use bool for booleans.
(writeline, check_file): Use uintmax_t for line counts.
(check_file): Check for and report line number overflow,
when that matters.
|
|
Include quote.h, xstrndup.h.
(TAB_STOP_SENTINEL): Increase from INT_MAX to INTMAX_MAX.
(convert_entire_line, have_read_stdin, parse_tabstops, next_file,

(first_free_tab, validate_tabstops, unexpand): Use size_t for sizes.
(add_tabstop, parse_tabstops, main): Don't reserve UINTMAX_MAX
as a tab stop.
(parse_tabstops): Don't use ISBLANK on possibly-signed char.
Detect overflow in tab stop string.
(next_file, main): Use EXIT_FAILURE/EXIT_SUCCESS instead of 1/0.
(unexpand): Concatenate input files the same way expand does.
|
|
|
|
(main): 0 -> STDIN_FILENO.
|
|
(have_read_stdin, count_items, scan_zeros, detect_loop,
recurse_tree, walk_tree, tsort, main):
Use bool for booleans.
(exit_status): Remove.
(tsort): Return a success flag instead of storing into a global.
(main): Use it.
|
|
touch, main): Use bool for booleans.
(main): Avoid integer overflow when given more than INT_MAX
options.
