实战Linux编程的原代码,希望对学驱动的人能有所帮助

	* doc/sh-utils.texi (false invocation): Describe how --help and
	--version are treated with and without POSIXLY_CORRECT.
	(true invocation): Likewise.  Forwarded by Michael Stone.

2001-03-18  Jim Meyering  <[e-mail]>

	* tests/Fetish.pm: If the $DJDIR envvar is defined, set SHELL
	to $DJDIR/bin/bash.exe.  Patch from Richard Dawe, based on a
	suggestion from Eli Zaretskii.

2001-03-10  Jim Meyering  <[e-mail]>

	* doc/sh-utils.texi (date invocation): Correct the description of how
	date works when given no format.  Reported by Ole Laursen.

	* src/factor.c: Include wheel-size.h.
	(WHEEL_START): Adjust definition.
	(wheel_tab[]): Remove body of definition.
	Include generated file, wheel.h, instead.

	* src/wheel-gen.pl: New file.
	* src/Makefile.am (noinst_HEADERS): Add wheel.h wheel-size.h.
	(EXTRA_DIST): Add wheel-gen.pl.
	(PERL): Define.
	(wheel-size.h, wheel.h): New rules.

2001-03-09  Jim Meyering  <[e-mail]>

	* Makefile.maint (my_distdir): Define new variable, and use this
	in place of most old uses of $(distdir).

	* src/date.c (usage): Describe %C.
	* doc/sh-utils.texi (Date directives): Likewise.

	* tests/help-version: Ensure that /dev/full is a character device
	(using test -c) as well as being writable, before trying to write to it.
	Otherwise, the test could mistakenly append a newline to an existing,
	regular, writable, /dev/full file.
	Suggested by Ulrich Drepper.

2001-03-07  Jim Meyering  <[e-mail]>

	* tests/stty/Makefile.am (EXTRA_DIST): Remove input-tty.

	Fix and clarify time zone usage in 'date' examples.

2001-02-04  Jim Meyering  <[e-mail]>

	* src/factor.c (usage): Tweak --help output: it prints the _prime_
	factors, not just any factors.

2001-02-03  Jim Meyering  <[e-mail]>

	Improve the performance of `factor' (more than 2x speed-up for large N).
	* src/factor.c (wheel_tab): New global table.
	(WHEEL_START, WHEEL_END): Define.
	(factor): Remove the loop that special-cased `2'.
	Instead of incrementing by `2', use the offsets from the wheel table.
	From Michael Steffens.

2000-11-27  Prashant TR  <[e-mail]>

	* src/test.c (eaccess) [__MSDOS__]: Just use access.

	that it's freed.

2001-01-20  Jim Meyering  <[e-mail]>

2001-01-04  Jim Meyering  <[e-mail]>

	* src/date.c (main): Fail when --rfc-822 (-R) is specified along

2000-12-08  Jim Meyering  <[e-mail]>

	* src/dirname.c: Include xalloc.h.
	(main): Use dir_name rather than the underlying dir_name_r.
	The former now handles cwd-relative names with drive-letter prefixes.

2000-12-02  Jim Meyering  <[e-mail]>

	* src/seq.c (valid_format): Move pre-increment to a separate statement
	to avoid a warning.

	* src/id.c: Move dcls of globals used only in main...
	(main): ...to here.

	* src/who.c: Likewise.

2000-11-13  Paul Eggert  <[e-mail]>

	* src/sys2.h (ST_TIME_CMP_NS): Fix typo: ST_MTIM_NSEC should
	be tested with #ifdef, not with #if.

2000-11-12  Jim Meyering  <[e-mail]>

	* src/date.c (show_date): Add a comment explaining why the
	format string must not be translatable via _().  From Paul Eggert.

2000-10-31  Jim Meyering  <[e-mail]>

	* doc/sh-utils.texi: Clean up indentation and punctuation.
	Fix a couple typos.  From Brian Youmans.

	* Makefile.am (EXTRA_DIST): Add .prev-version.

2000-10-18  Paul Eggert  <[e-mail]>

	* src/date.c (universal_time): Remove; it's just a temptation to
	do the wrong thing.
	(main): The -u option now just sets TZ; it doesn't do anything else.
	(show_date): Do not do anything special if -u is set.
	This affects the behavior of the -I and -R options.
	* doc/sh-utils.texi: Document the above.

2000-10-18  Jim Meyering  <[e-mail]>

	* doc/sh-utils.texi (Examples of date): Fix a typo.

2000-10-06  Paul Eggert  <[e-mail]>

	Undo the effect of the 1997-07-12 change to date.c; it
	broke "date -u MMDDhhmm" and it wasn't documented.
	This reverts to the behavior of the 1996-01-03 patch.

	* src/date.c (TZ_UTC0, MAYBE_SET_TZ_UTC0, set_tz): Remove.
	(batch_convert): Don't futz with TZ.

	above change.

2000-09-29  Jim Meyering  <[e-mail]>

	(also making it match the texinfo documentation).
	From Karl Eichwalder.

	* doc/sh-utils.texi (Setting the time): Correct the capitalization of
	`HHMM' in the info-rendering of the texinfo documentation.
	Reported by Karl Eichwalder.

2000-08-14  Jim Meyering  <[e-mail]>

	* src/tee.c (main): Remove incorrect `FIXME' comment.

2000-08-07  Paul Eggert  <[e-mail]>

2000-07-23  Jim Meyering  <[e-mail]>

	* src/help-version (su_args): Punt, so we don't try to start a shell.

	* src/su.c: Include <sys/param.h> if HAVE_SYS_PARAM_H is defined,
	rather than if _POSIX_VERSION is defined.  Remove declarations of
	getpwuid, getgrgid, and getuid, now that they're in sys2.h.
	Prompted by a report from John David Anglin.

	* src/sys2.h [!HAVE_DECL_GETPWUID]: Declare getpwuid.
	[!HAVE_DECL_GETGRGID]: Declare getgrgid.
	[!HAVE_DECL_GETUID]: Declare getuid.

2000-07-19  Jim Meyering  <[e-mail]>

	Reported by Michael Hohn.

2000-07-17  Jim Meyering  <[e-mail]>

	* src/stty.c (visible): Don't mark `<undef>' for translation.
	The standard requires that exact string.

2000-07-09  Jim Meyering  <[e-mail]>

	* config.guess: Update from FSF.
	* config.sub: Likewise.

	* src/Makefile.am (seq_LDADD): Don't hard-code `-lm' -- some systems
	don't have/need it.  From Bruno Haible.

2000-07-06  Jim Meyering  <[e-mail]>

	* src/help-version: Punt on `groups' test, since all it does
	is run `id -Gn', and groups fails if GNU id is not installed.
	Reported by Christian Krackowizer.

2000-07-05  Bruno Haible  <[e-mail]>

	* tests/nice: Avoid syntax error in "test" when `nice` generates

	so we can use AC_REQUIRE.
	(jm_BOOT_TIME): Likewise.

2000-06-17  Bruno Haible  <[e-mail]>

	* configure.in: Add pinky, users, who to OPTIONAL_BIN_PROGS if either
	<utmp.h> or <utmpx.h> exists. Add uptime only if either <utmp.h> or
	<utmpx.h> exists.
	* src/Makefile.am (bin_PROGRAMS): Remove pinky, users, who from here...
	(EXTRA_PROGRAMS): ... and add them here.

2000-06-26  Jim Meyering  <[e-mail]>

	`id -Gn' (invoked by groups) would fail without giving a diagnostic
	on malconfigured systems.
	* src/id.c (print_user): Give a diagnostic if number->name lookup fails.
	(print_group): Likewise.

2000-06-25  Jim Meyering  <[e-mail]>

2000-05-15  Jim Meyering  <[e-mail]>

2000-05-11  Jim Meyering  <[e-mail]>

	* src/date.c (usage): Don't call close_stdout_status directly,

	call close_stdout via atexit.
	* src/printenv.c: Likewise.
	* src/tty.c: Likewise.
