Hi

Please forgive if this is a stupid question but I'm a bit stuck and wondered if you could help?

I have a perl program that gets information about running processes on a server. I have a command that works on the command line but I can't get it to work in my perl script.

The command that works on the command line is:

ps aux | grep java | perl -e 'while(<STDIN>){if (/-Xmx((\d+)[gG])/) { 
+$mem += $2 } } print "total memory reserved by Java processes: ${mem}
+G\n"'

[download]

Which gives me: total memory reserved by Java processes: 58G

If I post this into my perl script no matter how I tweak it I can't get it to work.

Can you please help?
