Is there a command to automatically escape a string for use in sed?

I got frusturated escaping for simple replacement: https://github.com/jakeogh/replace-text

If you find yourself having to escape a lot of slashes, then you can do something like this:

echo "/foo/bar" | sed -e 's|/foo|/tmp|'

(The article mentions this)

It can be any character really. I like sed 's,foo,bar,' sed 's@foo@bar@'

Python has re.escape; awk can take variable definitions from the command line:

  echo b |awk '/b/{print a}' a=4
