Unix command to validate specific path in config file

Question

I need to validate a file path that repeats often in a file.

All file path that begins with /usr/local must be /usr/local/test. Ignore rest of the file paths like /usr/tmp (or) /usr/logs etc.

Answer 1

The following should find any lines which contain strings which contain /usr/local which do not match /usr/local/test.

sed -n 's%/usr/local/test%%;\%/usr/local%p' filename

If you just want the line numbers, = instead of p does that.
