Dont reinvent the wheel. With that said, here are some pointers :) ([EMAIL PROTECTED])(23/ttyp2)(04:26pm:04/28/00)- ($:~)- ps auxwww | grep q[m]ail qmaill 1482 0.0 0.2 848 144 ?

Will ONLY return anything containing qmail, however will ignore the 'grep' command line with qmail on it, since it doesnt exactly match the criteria, because the brackets are there. Give it a try. Aside from that, debian should also contain the 'pidof' command... eg. ([EMAIL PROTECTED])(22/ttyp2)(04:26pm:04/28/00)- ($:~)- /sbin/pidof qmail-send 1480 Aside from that, there are scripts and utilities already written that do exactly what you want, my favorite would be DJB's (the author of qmail) supervise package.
