.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides one function, \f(CW\*(C`killall()\*(C'\fR, which takes two parameters:
a signal name or number (see \f(CW\*(C`kill()\*(C'\fR) and a process pattern. This pattern
is matched against the process' command-line as the \f(CW\*(C`ps\*(C'\fR command would
show it (\f(CW\*(C`ps\*(C'\fR is not used internally, instead a package called
\&\f(CW\*(C`Proc::ProcessTable\*(C'\fR is used).
.PP
\&\f(CW\*(C`killall\*(C'\fR 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 \f(CW$!\fR variable
will be set based on that last one that failed (even if a successful kill
happened afterward).
