how to replace ' with \' in sed ?

[verlager]

I have a js string bounded by single quotes ('') . That requires that I escape the single quote (') that occurs in "I'm" or "don't". I want "I'm" to become "I\'m".

Fair enough. But this doesn't work: sed -e "s/\'/\'/g"

The replacement string is unescapable I believe and must be a literal.

How do I do this in sed ?

echo "I'm" | sed -e "s/'/\\\'/g"

Your solution works perfectly! Thank you so much! This had befuddled me for half an hour.
