Search And Replace in Multiple Files Using Perl

This blog post is pretty old. Be careful with the information you find in here. The Times They Are A-Changin'

perl -pi -w -e 's/search/replace/g;' *.php -e means execute the following line of code. -i means edit in-place -w write warnings -p loop

Example I had the following style sheet in a section:

and I wanted the following instead:

As each expression is a regular expression you’ve got to escape the special characters such as forward slash and . ../includes/style.css

So the final line of code ends up as perl -pi -w -e ‘s/../includes/style.css/admin.css/g;’ *.php
