I would like to replace a set of characters with corresponding characters from another set, something like this:
original set: ots "target" set: u.x foobartest → fuubar.ex.
Translations/transliterations like this are the specialty of the
$ echo 'foobartest' | tr 'ots' 'u.x' fuubar.ex.
tr doesn't support changing files in-place like
I would like to use
sed so I don't have to reinvent the wheel of juggling temp files.
