I’ve got a text input string in unix that I want to parse and replace all of the following characters [\^$.|?*+(){} with the same character preceded by an \.

(I am trying to backslash escape all the special characters used by grep before I feed the string into grep.  Don't ask - not my original code.)

For example, "this \is an $xample" would become "this \\is an \$xample".

What would be the easiest way to do this?

I got this to work : sed -e "s/\([[\^$.|?*+(){}]\)/\\\\\1/g” test.txt

hope this helps someone.
