Ron Yorston	0b6ec06beb	kill: add '--' option to separate options from arguments Using a negative pid to send TERM to a process group results in an obscure error: $ ./busybox kill -12345 kill: bad signal name '12345' This is intended. Manpage says: ARGUMENTS pid Each pid can be one of four things: ... -n where n is larger than 1. All processes in process group n are signaled. When an argument of the form '-n' is given, and it is meant to denote a process group, either a signal must be specified first, or the argument must be preceded by a '--' option, otherwise it will be taken as the signal to send. However, we did not support "--". Add this capability to BusyBox. function old new delta kill_main 993 999 +6 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2017-08-28 14:03:13 +02:00

Denys Vlasenko	ab77e81a85	klibc-utils: new applets: resume, nuke, minips minips is a pure alias to ps, just in case someone needs 100% klibc-utils compat. nuke is a primitive version of "rm -rf" without options and error checks. ~30 bytes. resume is a tool for initramfs which resumes from a given block device. function old new delta resume_main - 582 +582 packed_usage 31640 31712 +72 nuke_main - 28 +28 xstrtoull - 24 +24 applet_names 2646 2665 +19 applet_main 1532 1544 +12 applet_suid 96 97 +1 applet_install_loc 192 193 +1 applet_flags 96 97 +1 ------------------------------------------------------------------------------ (add/remove: 5/0 grow/shrink: 6/0 up/down: 740/0) Total: 740 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2017-08-18 19:15:29 +02:00
