在Linux中的文件中替换单引号和双引号

Question

I took a dump from postgres which created a bunch of CSVs, which have single (') and double (") characters in a few huge files.

How can I replace these with \\" and \\' in linux?

Thanks!

You can use sed :

sed "s/['\"]/\\\\&/g" <<< "abc'def',\"foo\",bar"

abc\'def\',\"foo\",bar

If you want to avoid escaping already escaped quotes then use:

sed -E "s/(^|[^\\])(['\"])/\\1\\\\\\2/g" file
