How to replace a path with another path in sed?

Question

I have a csh script (although I can change languages if it has any relevance) where I have to:

sed s/AAA/BBB/ file

The problem is that AAA

Answer 1

In circumstances where the replacement string or pattern string contain slashes, you can make use of the fact that GNU sed allows an alternative delimiter for the substitute command. Common choices for the delimiter are the pipe character | or the hash # - the best choice of delimiting character will often depend on the type of file being processed. In your case you can try

sed -i 's#/path/to/AAA#/path/to/BBB#g' your_file

Note: The g after last # is to change all occurrences in file if you want to change first ouccurence do not use g
