On Ubuntu if you have a file compressed as .tgz you can check its contents with this command
tar -tf filename.tgz
Or if you have a .gz file and you want to check its contents, you can do so with this command
gzip -cd <filename> | more
I have not tested these commands on other Linux distributions but I guess they would also work.
