Also consider posting to justlinux.com, but be aware they are even more insistent upon people using descriptive subject headers for their posts.

Sorry I cannot be of more help, I have not done much shell scripting.

you can add 'set -x ' at the top of your script to switch debugging on .(set +x for off)

you can try to execute the command within quotes in command line first, to check for proper outpur.

you can use "grep $n1 filename" to search in a file.
