After doing my usual googling and browsing for the right way of doing things, I finally gave up on this one. :( Seems that all documents with examples for **grep** are filled with explanations on regular expressions and advanced usages. Even _man_ and _info_ don't show SIMPLE and BASIC examples, and even with trial 'n error I couldn't figure out the right syntax and delimiters. Would anyone point me to some very basic but extensive page on grep usage ? All I need to do right now is something like: df -m | grep [ 'ilesystem' , '/dev/foobar' ] (I need to show any line containing _either_ of the strings) so that a script could output just the header line of 'df' plus the single line describing '/dev/foobar' below it. Thnx . . . Thiers
