NAME¶
killall - Kill all instances of a process by pattern matching the command-line
SYNOPSIS¶
use Proc::Killall;
killall('HUP', 'xterm'); # SIGHUP all xterms
killall('KILL', '^netscape$'); # SIGKILL to "netscape"
DESCRIPTION¶
This module provides one function, "killall()", which takes two
parameters: a signal name or number (see "kill()") and a process
pattern. This pattern is matched against the process' command-line as the
"ps" command would show it ("ps" is not used internally,
instead a package called "Proc::ProcessTable" is used).
"killall" searches the process table and sends that signal to all
processes which match the pattern. The return value is the number of processes
that were successfully signaled. If any kills failed, the $! variable will be
set based on that last one that failed (even if a successful kill happened
afterward).
