[PHP] OT Regular Expression [grep]
I know this is off-topic but what I'm using it for will be in a PHP script! All you who are grep-masters I have a question. I would like to find all processes by a given user on a linux box and kill them. I know this much: ps -u username Now, do I then pipe that to grep somehow and get just the PID's? How can I do this quickly and easily? -- Thomas Deliduka IT Manager - New Eve Media The Solution To Your Internet Angst http://www.neweve.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

(1) look up system / backtick operator / ... to get the output of the
grep call as array, one line per entry
(2) do a
foreach ($TheOutput as $Line) {
if (preg_match ('/^\s*(\d+)/', $Line, $Matches)) {
$PID = $Matches [1];
// kill it
}
}
