I have a question on 'tar' usage.
I have a dozen tarballs, (*.tar.gz) in these files is 5-10 text files. These text files do not have an extension, not that it really matters, but I would like to add (.txt) to each.
What I would like to do is put all these text files uncompressed into one big file or folder with one 'tar' command. I looked over the man page and the corresponding website but I am still a little confused.
