Grepping for a process will return the grep command, this can be avoided by adding '| grep -v grep' to a command or easier in some cases altering the regular expression by adding brackets around a character.

ps | grep 'ss[h]'


The regular expression 'ss[h]' matches the literal string 'ssh' when it appears in the process list, but does not accidentally match the string 'ss[h]' when it appears in the process list as 'grep ss[h]'.
