I like this bit of cleverness: # ps -xwa | grep [p]rocess-name This pattern will match what you're after but won't match itself. So, no need to grep -v grep! BTW, linux has the pgrep command now. Much nicer to use that grep'ing ps output. -- Matt -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
