how to grep multiple patterns

Padma Asrani — Thu, 05 Jul 2007 12:22:20 GMT

Hi

My requirement is that I wanted to grep multiple patterns from the output of some command.

For example

Output is

10 Selection Name XXX
44 isInterface TRUE
52 isIP TRUE
53 isIPX FALSE

I wanted to grep the value of Selection name XXX and also isIPF(FALSE) in a single command

Regards
Padma

As mentioned by several people, there is a -e option just for that. I'd use that over the egrep hammer.

You can also use -f file and put the patterns there. And finally, you can use one long quoted string with embedded newlines:
... | grep "Selection Name XXX
isIPX FALSE"
