Checking for multiple patterns in Unix


I writing a shell script to find if an object is merged to CVS head or not.Currently I am running a CVS command using the script to get an output to check the same.

eg. If the output has three specific tags... you come to know that its merged to head. If it has two or less, the code is not merged to head.

My intention is to automate the script further and get a refined output.

eg. I need help in writing a script that gives me an output "Merged to HEAD" if it finds the three tags in the output file and vice vera.

Something like:
egrep 'tag1|tag2|tag3' file

If that's the grep you're looking for, you can then pipe it into "wc -l" and do a quick test to see if it's less than 3.

Instead of just posting a vague description of your text and requirements, how about posting an actual example of the input, the desired output, and any code you've tried using so far?

The more (relevant) details you give, the less time we'll have to spend guessing what you mean, and the faster you'll be able to get the help you need.
