All the best!

Dear student,

         Good luck and all the best for USP annual examination.

Be confident and be cool; because you are going to do well in examination.

Read the QP slowly and decide about the questions to be attempt.

Better; try to attempt those answers first in which you are perfect.

In UNIX, first you need to explain the Topic; then write the Syntax with explanation of it; draw rectangle box around the Syntax written by you; then do not forget to give minimum 3 examples.

Write Question numbers clearly in the left shaded margin.

Use dark black ink ball pen.

Draw the figures wherever necessary.

After writing Shell and Perl programs draw rectangle box around them with output.

Remember the options of important Unix commands like ls, sort, grep, egrep, chmod, head, tail, cut, copy, paste, diff, comm, etc.

Your answers should be neat and spacious.

You have talents; prove it!.



Once again! good luck and all the best for annual examination!
