Spell out your words.

And what do you mean by "o/p"?? Center of WHAT screen?? Console/Xterm/Web? Are you wanting a GUI application, Applet, or CLI app???

You don't provide details, so we can't help you. Tell us what you're trying to accomplish, provide samples of the data, and we can try to assist.

Again, SPELL OUT YOUR WORDS, and provide decent details. You STILL provide no sample data, no details about your 'console' (Xterm? Serial? Size?? What??), and have not yet said what an "o/p" is, or what your'e doing to read it.

Answer the questions, provide details, or we won't be able to help you.

I *think* he wants to say OutPut.

@OP:
1.) clear cli with 'clear'.
2.) echo blanks until middle of screen reached.
3.) read -r line < file1 for i/p of first line in file into var line
4.) echo $line
5.) repeat step 1-4 for file2, file3 and so on
