nirvana replacements.tsv file.txt -o file.txt

Where a replacements.tsv file looks like this:

ADDRESSREREPLACEMENTFLAGS
,foobar2

The program will escape whitespace and other relevant characters in both the RE and REPLACEMENT columns, so no special regex commands like ,s/foo/&&/g etc.

Of course, it relies on /bin/ed, so not fully portable.
