Unfortunately, the grep -w option is not included in the standards, so it might or might not work on your system. (This is one of the reasons why you should always tell us what operating system you're using when you start a thread here.)

If grep on your system supports the -w option, it is a great choice for what you are trying to do. Otherwise, please tell us what operating system you are using and show us some representative sample data so we can make alternative suggestions to help you.

Hi.

There is a grep work-alike written in perl at https://fastapi.metacpan.org/source/...1.013/bin/grep which implements the -w option:
Code:
    -w  Matches must start and end at word boundaries. This is currently
        implemented by surrounding each pattern with a pair of "\b", the Perl
        regular expression word boundary metasequence. See perlre for the
        precise definition of "\b".

This is one of a number of the (BSD) *nix tools written in perl. So if you have perl, you could get this capability. I have used this in situations where the local toolset does not include a useful option. A list and links to that toolset is at PerlPowerTools-1.013 - BSD utilities written in pure Perl - metacpan.org

Best wishes ... cheers, drl
