Search and Replace over Multiple Files
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
