Code:

perl -pi.bak -e 's/some_string/new_string/g'  dir/*

will replace "some_string" with "new_string" in every file in the dir subdirectory, preserving the original files with a ".bak" suffix.

Althought the perl oneliner is sufficient, beginners may like to try Regexxer.

The advantage is a preview and a one-by-one replace which is helpful for more complicated regular expressions.
