Bourne shell error if/then/else

Comment:

Hi all, I'm trying to get a if/then/else check with a integer comparison on wc -l, but not having much luck. I want to check if there are a certain number of processes running, and if so, print sucess message/run something else. So far all I get are errors when I do #!/bin/sh ps -ef | grep tomcat | if [wc -l -ne 2]; then echo "Not running" else echo "Running" fi Any suggestions/ideas on where I'm going wrong? Thanks in advance, elpico.

if [ `ps -ef | grep -c tomcat` -ne 2 ] ; then echo "Not running" else echo "Running" fi

Thanks for that! - I think I was focusing too much on using the wc -l command. Cheers, elpico.
