sush: new applet

2023-04-23T14:14:55+00:00

Introduce the new applet sush. It's like su but it permits additional arguments on the command line which are passed to the elevated shell. Adds 144-168 bytes. (O bytes if it's not enabled.)

su: properly quote command

2023-04-23T14:12:44+00:00

Previously the command passed to the elevated shell was placed in literal double quotes on the command line. Instead it should be subject to full quoting by the quote_arg() function. Tweak command line processing. Costs 24-32 bytes.

win32: export xappendword()

2023-04-23T08:04:01+00:00

Export the function xappendword() from make. Use it in drop and watch. Saves 8-80 bytes, an unusually large disparity.

win32: case-sensitivity in tab completion

2023-04-19T11:51:19+00:00

The tab-completion code treated all matches as case-insensitive because that's how Microsoft Windows handles filenames. This is now inadequate, as shell builtins, functions and aliases are case sensitive. Modify the treatment of case-sensitivity in tab completion: - Track whether each potential match is case-insensitive (filename) or case-sensitive (shell builtin, function or alias). - When comparing matches use a case-insensitive comparison if either value is a filename. Otherwise use a case-sensitive comparison. Adds 64 bytes.

dd: omit direct flag

2023-04-18T10:44:57+00:00

O_DIRECT isn't supported with open(2) on Microsoft Windows. All code related to the 'direct' input/output flag can be omitted. Saves 160 bytes.

readlink: support --, -n always

2023-04-16T16:01:44+00:00

POSIX will be standardizing readlink (just the -n option) and realpath (just -E and -e options): https://www.austingroupbugs.net/view.php?id=1457 Change things for readlink so that the POSIX-mandated -n and -- work even when disabling the non-standard (and partially non-working) -f when FEATURE_READLINK_FOLLOW is clear. POSIX also wants readlink to be verbose by default (if the argument is not a symlink, readlink must output a diagnostic); I did NOT address that one, because I'm waiting to see what the GNU Coreutils folks do: https://lists.gnu.org/archive/html/bug-coreutils/2023-03/msg00035.html Partial fix for https://bugs.busybox.net/show_bug.cgi?id=15466 function old new delta packed_usage 34538 34557 +19 Signed-off-by: Eric Blake Signed-off-by: Denys Vlasenko

tr: display usage for incorrect arguments

2023-04-16T15:54:00+00:00

ash,hush: tab completion of functions and aliases

2023-04-16T15:15:05+00:00

Since commit 9e2a5668f (ash,hush: allow builtins to be tab-completed, closes 7532) ash and hush have supported tab completion of builtins. Other shells, bash and ksh for example, also support tab completion of functions and aliases. Add such support to ash and hush. function old new delta ash_command_name - 92 +92 hush_command_name - 63 +63 ash_builtin_name 17 - -17 hush_builtin_name 38 - -38 ------------------------------------------------------------------------------ (add/remove: 2/2 grow/shrink: 0/0 up/down: 169/-55) Total: 100 bytes Signed-off-by: Ron Yorston Signed-off-by: Avi Halachmi Signed-off-by: Denys Vlasenko

wget: enable progress bar in default configuration

2023-04-16T12:52:49+00:00

For some reason the progress bar in wget has never been enabled. Costs 1536-1600 bytes.
