You would: 

1. open the file for reading
2. read each line in the file
3. check each line for your desired pattern

That is what grep does. By doing this in Perl, you save having to create 
another process. You can combine the step of finding the pattern and extracting 
information from the desired line. You can also quit after you have found the 
line you are seeking, if you only need to find one match; grep will continue to 
read the rest of the file looking for more matches.

Let us know if you have problems with any of these steps.
