Searching for multiple strings with grep

Filed under: Shell Script Sundays — TheLinuxBlog.com at 9:36 pm on Sunday, August 23, 2009

Sometimes when using grep it’s nice to be able to search for more than one string in a file. It’s actually pretty easy to do, if you can remember the simple syntax. Basically, you pipe the terms together in double quotes and escape the pipe.

grep "gnome\|kde" install.log

The above example will search for gnome or KDE. It works for more more than one term, and also works with the invert match -v option, to exclude lines that include gnome or kde.

Todays article extra short, and late, but better late and short than none at all I guess.
