* pkill(1) first appeared in /usr/bin, but later it was moved to /binyar2008-08-311-756/+0
| | | | | | | for the convenience of rc.d. Now it has happily lived there for quite a while. So move the pkill(1) source files from usr.bin to bin, too. Approved by: gad
* Fix and extend the -j option to pkill/pgrep WRT the jailyar2006-11-231-7/+25
| | | | | | | | | | | | | | | | | | | | | wildcard specifications. Earlier the only wildcard syntax was "-j 0" for "any jail". There were at least two shortcomings in it: First, jail ID 0 was abused; it meant "no jail" in other utils, e.g., ps(1). Second, it was impossible to match processed not in jail, which could be useful to rc.d developers. Therefore a new syntax is introduced: "-j any" means any jail while "-j none" means out of jail. The old syntax is preserved for compatibility, but now it's deprecated because it's limited and confusing. Update the respective regression tests. While I'm here, make the tests more complex but sensitive: Start several processes, some in jail and some out of jail, so we can detect that only the right processes are killed by pkill or matched by pgrep.

* Sync as close as possible with NetBSD.pjd2005-11-161-92/+115
| | | | | | | | | | | | | | | This includes fixes and cleanups listed below: - If a process dissappears while we are signalling it, don't count it as a match/error. - Better handling of errors and messages. - Downgrade failure to kill(2) (other than ESRCH) from fatal error to a warning; otherwise processing aborts and possibly matching killees would remain unsignalled. This makes pkill match the Solaris behavior. - Exit with 2 on usage errors as documented. Obtained from: NetBSD Glanced at by: maintainer (gad) [a bit different version of this patch]
* I often find myself doing:pjd2005-11-161-14/+42
| | | | | | | | | | | | | | % pgrep <something> [to verify which processes match] % pkill <something> To speed such operation up, add -I option which works like rm(1)'s -i option (unfortunately -i is already used in pkill(1)), ie. pkill will ask for confirmation before killing each matching process. After adding -j, -F, -i, -S, -o and -L options and other improvements, I think I can add myself to the copyright header. Glanced at by: maintainer (gad)

* - Introduce '-S' option which allows to match system processes (pgrep only).pjd2005-03-201-20/+18
| | | | | | | | | | | | | - Rename IS_KERNPROC() macro to PSKIP() and extend its functionality. Now it'll skip calling process and system processes when -S is not given. As a side effect it fixes '-n' option. Before it was always matching calling process (because of missing 'if (kp->ki_pid == mypid)' check) and after that, calling process was ignored. - When '-l' option is given and there are no arguments, use p_comm as an arguments list (this is helpful for kernel threads matching).
