Replace string within text files using Perl

Replace string within text files using Perl

To Replace string within text files using Perl all you have to do is:

perl -pi -e 's/oldstring/newstring/g' *

The search string has to be written in regular expression format so if you plan to replace for example a path with slashes such as "/my/path" to "/new/path"
you have to mask the special characters by using backslashes like this:

perl -pi -e 's//my/path//new/path/g' *

and that’s it.
