How to ensure that string interpolated into `sed` substitution escapes all metachars
1 answer
What characters do I need to escape when using sed in a sh script?
3 answers
I have a shell variable which will be used within the replacement string of a sed regex.
Therefore, all characters &, / and need to be escaped by a preceeding .
I managed to do it for & and / by
newvar=`echo "$oldvar" | sed -e 's|&|\&|g' -e 's|/|\/|g'`
1st question: Is this fine (piping content to sed via echo etc.)?
2nd question: Somehow I cannot get it to work for the backslash. Can you show me how to do it?
