Yes, that works! Thanks. In reading the ps man page to learn what those options are, I see there's LOTS of info to get from the ps command.

Know what you mean ;-) Try using the `w' flag to ps: ps axfrww | grep webmin That should do it.

I can always figure out which one is webmin as it is listening on port 1 and I can see it in the sockstat output. I just thought if I could change the name listed in ps, then I wouldn't have to take the extra step to identify it.

Here's the beginning of the script: No - in Perl, a "package" is a namespace - an abstract storage space. It helps keep a module's (i.e. package's) variables etc logically separate from those of other packages. It prevents collisions in variable names, data structures, etc. The variable $0 contains, by default, the name of the file containing the currently running script. > > #!/usr/bin/perl > # A very simple perl web server used by Webmin > > $0='webmin'; > > # Require basic libraries > package miniserv;<-- This is just declaring that the following code is in the "miniserv" package. > use Socket; > use POSIX; > > Then a little farther in the script, I see this code: > > # Get miniserv's perl path and location > $miniserv_path = $0; > open(SOURCE, $miniserv_path); > =~ /^#!(\S+)/; $perl_path = $1; > close(SOURCE); > @miniserv_argv = @ARGV; > > So I suspect the process name gets set in this somewhere? As you have poked $0 before it gets this far, no - $0 contains the value you set above. Which might, in itself, cause problems later in the script. Without reviewing it, I couldn't tell you.

(perl) Thank you both for your answers. I'm not much of a scripter but I tried your suggestion with the webmin script. I found that the actual file is /usr/local/lib/webmin/miniserv.pl and edited the beginning of the file as such: #!/usr/bin/perl # A very simple perl web server used by Webmin $0='webmin' # Require basic libraries package miniserv; However when starting the program it dies with the following message: syntax error at /usr/local/lib/webmin/miniserv.pl line 7, near "package miniserv" BEGIN not safe after errors--compilation aborted at /usr/local/lib/webmin/miniserv.pl line 8. Is there something really easy I'm missing? If it's complicated I'm going to forget it as it's not that important.

Re: Can I Set Process Name?
> setproctitle(3) - but I don't know how you would call it from perl. You can do it by altering the $0 variable: #!/usr/bin/perl -w use strict; $0='Will it work?'; sleep (10); A ps | grep 'Will' gives me: 2551 p3 SN 0:00.02 Will it work?
