I find from website that its uncompress .Z

is that correct?
replies would be appreciated.
thanks!

a few pointers;

use the 'file' command to determine what type of file you're dealing with. This doesn't just work for compressed files, this works for all files. It's useful because a file extension can be anything, you can call things what you want. The 'file' command examines the actual contents of the file and returns a guess at the contents by matching it up with a database of 'fingerprints' (/etc/magic) See below

# file passwd.Z
passwd.Z: compressed data block compressed 16 bit

In this example I've used the file command to determine that the file 'passwd.Z' is a compressed file made using the UNIX 'compress' command.

And yes, you're right, you uncompress these files using the command 'uncompress' - but you have to tell it the exact file you want to uncompress! So in your case you want to use 'uncompress software.all.Z'

Hope this helps!

Also - I'm not meaning to be condescending, but your command line skills are a little lacking. I wouldn't normally be this horrible, but as most AIX boxes are used in corporate environments i fee i should. If you're doing this stuff at work on a production system then be damn sure you either know what you're doing or have the sign-off from a direct superior, messing around on the command line is an excellent wasy to lose your job!

Alex: thanks for ur advice. its very well taken.
I was just testing doing aix at home and not in production env.
Iam still a novice and trying to learn at my pace.
Thanks very much
