Use cp -R -L --copy-contents to get the + traditional (and rarely desirable) cp -r behavior. +* ls now accepts --time-style=+FORMAT, where +FORMAT works like date's format +* The obsolete usage `touch [-acm] MMDDhhmm[YY] FILE...' is no longer + supported on systems conforming to POSIX 1003.1-2001. Use touch -t instead. +* cp and inter-partition mv no longer give a misleading diagnostic in some + unusual cases +[4.1.5] +* cp -r no longer preserves symlinks +* The block size notation is now compatible with SI and with IEC 60027-2. + For example, --block-size=1MB now means --block-size=1000000, + whereas --block-size=1MiB now means --block-size=1048576. + A missing `B' (e.g. `1M') has the same meaning as before. + A trailing `B' now means decimal, not binary; this is a silent change. + The nonstandard `D' suffix (e.g. `1MD') is now obsolescent. +* -H or --si now outputs the trailing 'B', for consistency with the above. +* Programs now output trailing 'K' (not 'k') to mean 1024, as per IEC 60027-2. +* New df, du short option -B is short for --block-size. +* You can omit an integer `1' before a block size suffix, + e.g. `df -BG' is equivalent to `df -B 1G' and to `df --block-size=1G'. +* The following options are now obsolescent, as their names are + incompatible with IEC 60027-2: + df, du: -m or --megabytes (use -BM or --block-size=1M) + df, du, ls: --kilobytes (use --block-size=1K) +[4.1.4] +* df --local no longer lists smbfs file systems whose name starts with // +* dd now detects the Linux/tape/lseek bug at run time and warns about it. +[4.1.3] +* ls -R once again outputs a blank line between per-directory groups of files. + This was broken by the cycle-detection change in 4.1.1. +* dd once again uses `lseek' on character devices like /dev/mem and /dev/kmem. + On systems with the linux kernel (at least up to 2.4.16), dd must still + resort to emulating `skip=N' behavior using reads on tape devices, because + lseek has no effect, yet appears to succeed. This may be a kernel bug. +[4.1.2] +* cp no longer fails when two or more source files are the same; + now it just gives a warning and doesn't copy the file the second time. + E.g., cp a a d/ produces this: + cp: warning: source file `a' specified more than once +* chmod would set the wrong bit when given symbolic mode strings like + these: g=o, o=g, o=u. E.g., `chmod a=,o=w,ug=o f' would give a mode + of --w-r---w- rather than --w--w--w-. +[4.1.1] +* mv (likewise for cp), now fails rather than silently clobbering one of + the source files in the following example: + rm -rf a b c; mkdir a b c; touch a/f b/f; mv a/f b/f c +* ls -R detects directory cycles, per POSIX. It warns and doesn't infloop. +* cp's -P option now means the same as --no-dereference, per POSIX. + Use --parents to get the old meaning. +* When copying with the -H and -L options, cp can preserve logical + links between source files with --preserve=links +* cp accepts new options: + --preserve[={mode,ownership,timestamps,links,all}] + --no-preserve={mode,ownership,timestamps,links,all} +* cp's -p and --preserve options remain unchanged and are equivalent + to `--preserve=mode,ownership,timestamps' +* mv and cp accept a new option: --reply={yes,no,query}; provides a consistent + mechanism to control whether one is prompted about certain existing + destination files. Note that cp's and mv's -f options don't have the + same meaning: cp's -f option no longer merely turns off `-i'. +* remove portability limitations (e.g., PATH_MAX on the Hurd, fixes for + 64-bit systems) +* mv now prompts before overwriting an existing, unwritable destination file + when stdin is a tty, unless --force (-f) is specified, as per POSIX. +* mv: fix the bug whereby `mv -uf source dest' would delete source, + even though it's older than dest. +* chown's --from=CURRENT_OWNER:CURRENT_GROUP option now works +* cp now ensures that the set-user-ID and set-group-ID bits are cleared for + the destination file when when copying and not preserving permissions. +* `ln -f --backup k k' gives a clearer diagnostic +* ls no longer truncates user names or group names that are longer + than 8 characters. +* ls's new --dereference-command-line option causes it to dereference + symbolic links on the command-line only. It is the default unless + one of the -d, -F, or -l options are given. +* ls -H now means the same as ls --dereference-command-line, as per POSIX. +* ls -g now acts like ls -l, except it does not display owner, as per POSIX. +* ls -n now implies -l, as per POSIX. +* ls can now display dates and times in one of four time styles: + + - The `full-iso' time style gives full ISO-style time stamps like + `2001-05-14 23:45:56.477817180 -0700'. + - The 'iso' time style gives ISO-style time stamps like '2001-05-14 ' + and '05-14 23:45'. + - The 'locale' time style gives locale-dependent time stamps like + 'touko 14 2001' and 'touko 14 23:45' (in a Finnish locale). + - The 'posix-iso' time style gives traditional POSIX-locale + time stamps like 'May 14 2001' and 'May 14 23:45' unless the user + specifies a non-POSIX locale, in which case it uses ISO-style dates. + This is the default. + + You can specify a time style with an option like --time-style='iso' + or with an environment variable like TIME_STYLE='iso'. GNU Emacs 21 + and later can parse ISO dates, but older Emacs versions cannot, so + if you are using an older version of Emacs outside the default POSIX + locale, you may need to set TIME_STYLE="locale". + +* --full-time is now an alias for "-l --time-style=full-iso". + +Changes in release 4.1: +[4.0.45] +* dd conv=sync,block now pads only with spaces +* ls's -1 option no longer cancels the effect of a preceding -l +* regenerate configure using a patched version of autoconf-2.49e to work + around a bug in its test for a working memcmp function +* ls: fix off-by-one error introduced with the previous change +[4.0.44] +* ls: When given two or more arguments but the only one that exists is a + directory, don't treat it as if it were the only argument. Before, + `mkdir d; ls no-dir d 2>/dev/null' would act like `ls d' and produce + no output. Now, it prints `d:'. +* touch -d 'last friday' would use a time stamp that was one hour off + (e.g., 23:00 on *thursday* rather than 00:00 of the preceding friday) + when run such that the current time and the target date/time fall on + opposite sides of a daylight savings time transition. + This problem arises only with relative date strings like `last monday'. + It is not a problem with strings that include absolute dates. +[4.0.43] +* regenerate configure-related files using autoconf-2.49d +[4.0.42] +* Using ls's short-named `-H' option evokes the warning that the + meaning of `-H' will soon change. Use `--si' instead. +[4.0.41] +* fix bug in rm introduced in 4.0.38: `chmod 0 f; rm f' would no longer prompt + before removal. +[4.0.40] +* portability fixes, mainly for UnixWare 7.1.1 +[4.0.39] +* cp and mv accept --strip-trailing-slashes, not just --strip-trailing-slash +[4.0.38] +* ls --full-time now implies -l; before, without -l it was a no-op +[4.0.37] +* portability fixes for SunOS4.1.1, Fujitsu (f300-fujitsu-uxpv4.1_ES), + and Unicos (alphaev5-cray-unicosmk2.0.5.X) +[4.0.36] +* `mv dir/ new-name' no longer fails on SunOS4.1.1U +* attempting to use mv to move a symlink onto itself no longer removes + the symlink +* `cp -R directory file' no longer removes `file'. now it fails and gives + a diagnostic +* The manual now warns that ls's --full-time format string is planned + to change in a future release. +* ls -l's time stamp format now depends on LC_TIME, not LC_MESSAGES, + as POSIX requires. +* ls -l now reports the year for files even slightly in the future, as + POSIX requires.

Other uses with a numeric group ID would cause + chown to fail when it shouldn't have. +* the chown and chgrp programs preserve set-uid and set-gid bits, even on + systems for which the chown function call resets those bits. +* `ls -L dangling-symlink' now fails (per POSIX) rather than printing the + link name +* dd no longer honors the just-added `B' suffix on skip= and seek= arguments. +* `mkdir no-such-dir/' no longer fails on NetBSD systems +[4.0.33] +* dd now accepts skip=nB and seek=nB, to advance past some number of bytes, n, + that need not be a multiple of the block size. +* dd (without conv=notrunc) now complains only when ftruncate fails on a + regular file, a directory, or a shared memory object -- not when it fails + to truncate other types of files, like /dev/fd0. +* chmod --changes (-c) once again issues diagnostics only for the files + with changed permissions +* mkdir now gives one diagnostic (rather than two) for certain failures +* mkdir portability fix for NetBSD +[4.0.32] +* touch now interprets a lone numeric argument of 8 or 10 digits as a file name, + rather than as a date/time in the obsolescent `MMDDhhmm[YY]' format. +* mkdir no longer sets the permissions of the final directory component + if it already exists (this bug, too, was introduced recently) +* ls's --full-time format string is now locale dependent +[4.0.31] +* mkdir: fix a bug introduced in 4.0.30 whereby `mkdir existing-dir' would + succeed.

Use -N to get the old default behavior. + The new behavior is also enabled by the new option -e or --quote-shell. +* ln --backup is now consistent with cp and mv in that --force is no longer + required when the destination is an existing non-directory. +* install accepts new option, --verbose (-v) +* mkdir -p is a lot faster when creating very deep directories on some systems +* rm -i no longer exits with status indicating failure solely because the + user declines to remove a file +* rm -r is a lot faster on some systems when removing deep hierarchies +* chgrp, chmod, and chown no longer give contradictory output when --verbose + is used and an operation fails +* ls's multicolumn option now uses variable width columns to conserve + vertical space +* install accepts new option, --preserve-timestamps +* du --megabytes --total now shows total in megabytes +* ls accepts new option, -h or --human-readable +* df, du, and ls now accept new option, -H or --si, for powers of 1000 not 1024 +* df, du, and ls now consistently round to nearest, with ties going to even +* df, du, and ls now use `k' instead of `K' for `kilo', + and support larger abbreviations T(era), P(eta), E(xa), Z(etta), Y(otta) +* touch -d DATE now works on Unicos +* du accepts new option --max-depth=N +* rmdir accepts new options: --ignore-fail-on-non-empty and --verbose +* on most hosts df, du, and ls now overflow at 2**64 bytes, not 2**31 bytes +* all programs now work on large files on LFS systems like Solaris 2.6 and + Linux with the pre-2.1 development version of GNU libc. +* df now works with OpenBSD 2.1 beta +* cp -d FILE SYMLINK-TO-FILE doesn't erase FILE.

Using --tabsize=0 + inhibits the use of TAB characters for separating columns. +* you can create a backup of FILE with cp --force --backup FILE FILE. Before, + that command failed saying that ``FILE' and `FILE' are the same file'. +* uses automake-generated Makefile templates +* chown and chgrp accept new option --no-dereference (-h) +* ln -f FILE FILE fails with a diagnostic rather than silently removing FILE +* when building on systems that have getopt_long (most GNU-oriented ones), + the system-provided function will be used -- so executables may be a + little smaller +* cp -p, and mv modify owner and/or group of symlinks on systems + (like Solaris) that provide the lchown system call. +* df no longer invokes the sync system call by default. You can use the + --sync option to make df invoke sync before getting file system sizes. +* internationalized diagnostic messages +* mkdir accepts new option: --verbose +* `cp file D/' uses the full file name `D/file' instead of `D//file'. +* cp --backup a~ a fails instead of silently destroying the source file +* df and du have new options --human-readable (-h) and --megabytes (-m). +* install now honors --backup (-b), --suffix=SUFFIX (-S SUFFIX), and + --version-control=WORD (-V WORD) options just as cp, ln, and mv do. +* ln --verbose output is less prone to misinterpretation +* ls -o works like -lG; for compatibility with other versions of ls +* cp has a new option to control creation of sparse files: + --sparse={auto,always,never}. --sparse=auto is the default. +* rm -rf '' behaves properly on SunOS 4 systems +* touch: rename long option name, --file, to --reference. + `touch --file' will continue to work a little longer. +* df fails if the same file system type is both selected and excluded. +* df works around SunOS statfs brokenness wrt filesystems larger than 2GB +* df better handles inconsistent mtab entries +* `ls -lDR dir dir2' works +* `ls -c' does what it's supposed to +* all programs include program name in --version output +* `ls --quote-name' works +* mv properly determines whether src and dest are the same file + Before, it could (though with very low probability) fail to do the move, + reporting that distinct source and destination are the same file. +* du --dereference (-L) works with directory symlinks +* du works on SunOS 4 systems even when accounting is enabled +* many programs that convert strings to integers now use strtol or strtoul + and detect overflow + +User-visible changes in release 3.12: +* None. +User-visible changes in release 3.11: +* None. +User-visible changes in release 3.10: +* mkdir -p now ignores arguments that are existing directories. Before, + (contrary to POSIX spec) it would attempt to change ownership and/or + protections of existing directories listed on the command line. And + it would fail when such a directory was owned by another user. +* Fix bug in cp that made the commands `mkdir dir; touch foo; cp -P foo dir' + incorrectly change the permissions on directory, dir. +* df accepts a new option, --no-sync, that inhibits the default invocation + of the sync system call. +* ls accepts a new option, --dired, that makes emacs' dired mode more efficient +* skeletal texinfo documentation (mainly just the `invoking' nodes) +* ln accepts a new option: --no-dereference (-n). With this option, + if the destination command line argument is a symlink to a directory, + use that as the destination instead of the file in the directory. +* `ln -i no-such-file existing-file' gives a diagnostic and fails. + Before, if you responded `yes' to the prompt it would both remove + `existing-file' and fail to make a link. +* du no longer requires read access to all of the directory components + of the current working directory on systems with fchdir. +* touch -d 'date' is no longer off by one hour. +* New program: sync. +* Fix bug in cp that made the commands `ln -s . s; cp -rd s r' incorrectly + create `r' as a symlink instead of as a regular file. +* du's -S and -c options now work when used together. + Before, the grand total was always reported to be zero. + +Major changes in release 3.9: +* --help gives a one-line description of each option and shows the + correspondence between short and long-named options. +* work around systems with BROKEN_STAT_MACROS +* work around problem where $(srcdir)/config.h was used instead of + ../config.h -- this happened only when building in a subdirectory + and when config.h remained in $(srcdir) from a previous ./configure. +* GNU chmod treats symlinks the same way other vendor's versions do. + Now symlinks listed on the command line are processed (they were + ignored before); the permissions of the dereferenced files are + changed. Symlinks encountered in recursive traversals are still + ignored. This makes GNU chmod act more like e.g. Sun's. +* configure uses config.h, so DEFS won't exceed preprocessor limits of + some compilers on the number of symbols defined via -D. +* ls and cp can handle mount points on more systems +* cp, mkdir, and rmdir long option --path renamed to --parents; --path + will still work for a while +* cp, ln, and mv convert `cp A B/' to cp A B/A when A is not a directory. + This change affects only the two-argument form of the commands. It makes + such commands fail when the target has a trailing slash but is not a + directory or symlink to a directory and the source is not a directory. + They used to succeed, ignoring the implicitly contradictory trailing slash. + +Major changes in release 3.8: +* install isn't as likely to produce spurious errors +* avoid redundant compilations for `dir' and `vdir'; +* configure properly defines STAT_STATFS2_BSIZE on a Pyramid MIServer + running OSx 5.1 + +Major changes in release 3.7: +* none +Major changes in release 3.6: +* `ln -s dir_pathname .' works when the pathname has a trailing slash +* with the --version option programs print the version and exit immediately +* GNU ls -f works like Unix ls -f +* mktime replacement works + +Major changes in release 3.5: +* adds support for DEC Alpha under OSF/1 +* configuring with gcc uses CFLAGS='-g -O' by default +* all programs accept --help and --version options +* long-named options must be introduced with `--'; `+' is no longer + accepted since it is incompatible with the POSIX.2 standard +* chmod accepts long-named options +* dd conv=unblock doesn't hang +* new df option --exclude=fstype +* new ls option --full-time + +Major changes in release 3.4: +* cp -p and mv preserve setuid and setgid bits +* chown works on systems where sizeof(uid_t) != sizeof(int) + or sizeof(uid) != sizeof(gid) +* catch errors from spurious slashes at ends of arguments + +Major changes in release 3.3: +* df sped up by not calling sync for every filesystem +* df ported to AIX (RS/6000 and PS/2), and SVR2 port fixed +* df -i now also prints the total number of inodes per filesystem +* ls sped up by not reading symlink contents unnecessarily +* du doesn't die on POSIX systems when the root filesystem is NFS mounted +* cp and mv report chown Permission denied errors when run by root + +======================================================================== + +Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, +2001, 2002, 2003 Free Software Foundation, Inc. + +Permission is granted to copy, distribute and/or modify this document +under the terms of the GNU Free Documentation License, Version 1.2 or +any later version published by the Free Software Foundation; with no +Invariant Sections, with no Front-Cover Texts, and with no Back-Cover +Texts.
