Help w/ sed parsing special characters

[clem_c_rock]

Hello,

I'm trying to change the image paths in a directory of files.

My first question is that I'm trying to use this line to test the change in one file:


sed -e 's/images/http://cache.somewebsite.com/images' ajax_scaffold.css

When I try that I get this:

sed: 1: "s/images/http://cache.r ...": bad flag in substitute command: '/'

I did a test by running this:

sed -e 's/images/duh/' ajax_scaffold.css

and the output said the changes had worked but when I went to the actual file, the changes didn't show?


Also, when I find a command that works, is it possible to specify a directory

and run this command on every file w/in the directory?

The problem with your sed command is that in sed, the '/' character indicates the delimiter of the sections. If you want to use '/' inside the pattern or replacement, you need to escape it, so that your line looks like:

sed -e 's/images/http:\/\/cache.somewebsite.com\/images' ajax_scaffold.css

(that is, every '/' preceded by a '\')

As for doing it to every file in a directory, just do:

sed -e 'PATTERN' directory/*

The /* means "all files inside the directory".
