Text searching in linux with grep

[Red Squirrel]

Grep is a linux command that is often overlooked but can be very useful when searching for stuff from a single string to a complicated regular expression. This article scratches the surface on it's power and should leave you with enough information to discover new uses for it.

These tests are done on RH8.0 which is considered somehwhat old so it could be possible that things got changed.

And the reason for the -l was to have 1 file per line, since the other is multiple files per line which achieves undesirable results in these examples. Though the results would of been the same if I would of put the words in a file line per line, but just wanted to show examples using real-time situations.

I think grep is only a linux thing, but there is a windows program that does the same but I forget what it's called.
