Treat /dev/tty as an alias for Windows' 'con' device. The code is similar to that used for /dev/null. Adds 24-48 bytes. (GitHub issue #538)

2025-11-08pgrep/pkill: fix -x to also match comm fieldDenys Vlasenko1-4/+4
When running `pgrep -x example` against a process `/bin/example --arg`, BusyBox fails to match, while GNU pgrep succeeds. The reason is that the comparison is done only against the full argv[0] rather than comm. This patch changes pgrep -x to also try /proc/[pid]/comm for exact matching. function old new delta pgrep_main 681 670 -11 Signed-off-by: Paulius Zaleckas <paulius.zaleckas@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Since commit 551bfdb97 (ls: implement -q, fix -w0, reduce startup time) the '--color' option behaves as though the default argument 'always' had been specified.

Convert the icons to PNG format (by simply exporting them from GIMP and selecting the 'Compressed (PNG)' chackbox). Allow these to be selected instead of ICO format at build time. Use the PNG icons by default in the Unicode and aarch64 builds. Saves 26KB in those cases. (GitHub PR #540)

2025-10-29Further tweaks to make_single_applets.shRon Yorston3-4/+13
Changes to the applet configurations of 'reset' and 'which' in the Microsoft Windows port resulted in these applets being enabled in every single-applet executable built by make_single_applets.sh.

Specifying a PID of 0 for the -p option of chrt would previously result in a "number 0... not in range" error. Now, it means instead that the calling process (i.e. chrt itself) should be operated on; this is to be consistent with the behavior of util-linux's version of chrt. function old new delta chrt_main 462 474 +12 Signed-off-by: Zuo An <zuoan.penguin@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2025-10-06ash: output '^C' when wait builtin is interruptedRon Yorston1-3/+13
When the wait builtin detects an interrupt it should print '^C' to stdout, as is done in other similar cases. Saves 16 bytes in the 64-bit build.
2025-10-05ash: allow ctrl-c to interrupt wait in presence of trapRon Yorston1-4/+21
Commit 387d01161 (ash: allow wait builtin to be interrupted) allowed the wait builtin to be interrupted by ctrl-c. However, this didn't work in the presence of a trap. When waitpid_child() detects an interrupt propagate this up the call stack so the wait builtin terminates and the trap is invoked. Adds 80-88 bytes. (GitHub issue #530)
2025-10-05ash: make ctrl-c trap handling closer to upstreamRon Yorston1-12/+10
Commit 64c8f5f3d0 (ash: add support for INT trap) didn't follow upstream behaviour. If a trap is supplied for SIGINT, upstream's signal handler detects this and doesn't call raise_interrupt(). The busybox-w32 implementation called raise_interrupt() but had it do nothing. Modify the code to match upstream's behaviour. Saves 16-36 bytes.
2025-10-03ash: allow wait builtin to be interruptedRon Yorston1-11/+12
After commit f6be217fa (ash: wait builtin should block) it wasn't possible to interrupt a call to wait with Ctrl-C. A blocking wait should be stopped from time to time to check for an interrupt. Adds 32 bytes. (GitHub issue #529)
2025-10-02ash: wait builtin should blockRon Yorston1-1/+1
It was found that the 'wait' shell builtin would use 100% of a core when waiting for a process to terminate: sleep 60 & wait This is a regression caused by commit bb8f6b688 (ash: fix slow running when background job is present). See the commit message and GitHub issue #434 for the long and involved history. The problem is in the Windows implementation of waitproc() in ash. The 'block' argument to waitproc() can take three values: DOWAIT_NONBLOCK DOWAIT_BLOCK DOWAIT_CHILD_OR_SIG The first two have obvious meanings. The third performs a non- blocking wait(2) and if no PID is returned it waits for SIGCHLD. So in effect it's a blocking wait. The Windows implementation would perform a non-blocking wait(2) but couldn't then wait for SIGCHLD, because Windows doesn't have such a signal. As a result the 'wait' builtin would loop calling waitproc(). To avoid this DOWAIT_CHILD_OR_SIG should be treated as a blocking wait in waitproc(). (GitHub issue #529)
2025-10-02Further mingw-w64/gcc build tweaksRon Yorston2-1/+8
Commit 6481bb22b (win32: use 64-bit time on 32-bit platforms) fails to build with mingw32-gcc prior to mingw-w64 10.0.0. Don't used 64-bit time for such builds. mingw-w64 7.0.0 and below don't have some definitions required for native TLS support. This is enabled by default in the 64-bit Unicode build. Add the definitions required for the default build. TLS 1.3 support needs more but isn't enabled by default. (GitHub issue #527)

Apply upstream commit f6fb3c603. This moves some static data into globals_misc. The Windows port had already moved commandname, so only g_parsefile and basepf are new. Some changes had to be made to the forkshell code. Adds 148-176 bytes.

2025-09-09ash: eval: Reset handler when entering a subshellRon Yorston1-14/+33
Apply upstream commit 81274d8b3. On Windows it isn't necessary to reset the exception handler in evalbackcmd() or evalpipe(), as that will have been done by forkshell_init(). The globals_misc structure now contains a setjmp() buffer. On 64-bit Windows this needs 16-byte alignment. This is achieved in the forkshell data structure by placing the globals_misc data immediately after the 16-byte aligned forkshell data. Saves 144 bytes in the 64-bit build.
