Looks like a bug...apparently caused by a race condition between the ps command and the shell spawning the grep command. > I've resolved the problem with > > if [ -n "`ps axc | grep -v grep | grep xntpd`" ]; then > > for now.

There's always: ps axc | sed /grep/d | grep xntpd -or- ps axc | sed -n '/sed/d;/xntpd/p' I'll stick this in the bug list for the next release, and see if anything more elegant pops to mind later...
