pgrep tomcat-5.5-26-rum OR pgrep "*-rum"

can some body help me how can i get tomcat process id by its name regex for "*-rum"

Answer Source

pgrep only search for the process name without the full path (in your case only java) and without arguments.

Since tomcat-5.5-26-rum is part of the latter, i'd search the pid with

ps -ef | grep tomcat-5.5-26-rum | grep java | awk ' { print $2 } '

The double grep is useful to discard the grep pids itself
