Howdy folks, I am newbie and am trying to figure out a way to search
for a set of files that are compressed within some .tgz folders and
copy these specified files into a new directory. Iam using RH
enterprise. I was looking around at different bash scripts. I didn't
know if it was possible to access files and copy them without having to
uncompress the folders. Is it possible?
Any help or suggestions people have is muchly aprreciated
thanks
