hey,
m new in scripting.
can anyone tell what command is to be used to call strings from other files to the script and then comparing strings from two different files in the script to check if strings are matched then return the result to another script.

For exact matches on two sorted files look at the "comm" program. It can list 3 columns. Unique in file 1, Unique in file 2 and common to both files. You can suppress columns to return what you want.

For code or generic text files, look at the diff command.
