Hi,
I am new to Linux OS. I want some shell script programs. Can you help me to find out.

1. Shell script that takes a login name as a command line argument and reports to you when that person logs in.

2. Shell script that takes three command line arguments. The First argument is name of the destination file and the other two arguments are names of the files to be placed in the destination file.

If anyone knows please give me the code.

Regards,
Gayathri

For you first question not sure what you're asking but look at finger perhaps.
For your second look at cat.

The descriptions sound suspiciously like cut&pasted homework assignments.

If you don't even know where to begin, find yourself a good scripting tutorial and start working through it.

Here are a few useful bash scripting references:
