If you have used sed then you have used the / delimiter

sed s/foo/bar/g file

You will also probably be aware the need to escape any slash in the string you’re trying to match, for example matching f/o/o would be

sed s/f\/o\/o/b\/a\/r/g file

What you may not know is you can use different delimiters to save yourself escaping any occurrence of slash in the string.

sed s%foo%bar%g file
sed 's|foo|bar|g' file
sed 's foo bar g' file

Note that some delimiters require quotes. Any occurrence of your chosen delimiter in the string will have to be escaped.

According to section 4.3 of the sed Info document you should be able to use “any single character”, giving you a lot of options to chose from in order to avoid all the escaping. To read this section of the Info document incant

info sed -n "regexp addresses"

Do you have a preferred delimiter or do you like a bit of variety?
