How to do a search and replace over multiple files
You could also use find and sed, but I find that this little line of perl works nicely.
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:
<link rel="stylesheet" type="text/css" href="../includes/style.css">
and I wanted the following instead:
<link rel="stylesheet" type="text/css" href="admin.css">
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
Or a more useful example of adding in an include to the head section:
perl -pi -w -e 's/<\/HEAD>/<?php include($_SERVER[DOCUMENT_ROOT]."\/includes\/tips_top.php");?>\n<\/HEAD>/g;' *.php
