kevin,
To answer your question, the 'greb' in your code is just part of a
string, it won't produce any effect.
and if what you wish is to remove your own grep process, this command
might do the trick.
ps -ef | grep hald-runner | grep -v grep
Tor.

Hello everyone:
When I am using a pattern match to find my wanted process, things like
this:
*********************************************************************************************
ps -ef | grep hald-runner
root 5006 5005 0 Mar04 ? 00:00:00 hald-runner
kevin 8261 3896 0 16:53 pts/10 00:00:00 grep hald-runner
*********************************************************************************************
but I don't want the second process item, so I write this code to
filter:
@array = qx{ps -ef | grep hald-runner};
chomp @array;
foreach ( @array ) {
if (/grep hald-runner/) {
next;
}
}
Here my confusion comes: What the grep here will mean??
Here "grep" is just a plain text or a verb which can help to grep
contents??
Thank you in advance.
