You'll often find that if you download a file, either the source code, or the executable itself (The Binary), it's followed by a .tgz suffix.
This means that the file has first been tarred (The t part of the suffix), which means that all the files for this particular download were put into one
big file. This is akin to taking a few episodes of startrek on separate tapes, and copying them onto one cassette. All the originals are there, you
just need to fast forward or rewind the tape to get to the right place for the one you want. The ironic thing, is that the program tar that was used
to create the archive can actually spool through a backup cassette too (
And you think all my analogies are meaningless ;).
The other part of the suffix is gz. This means that the tar archive was compressed using gunzip. The nice thing is that for uncompressing the original
files, you dont have to run gunzip first, and then tar. Both can be executed with a simple command.
To uncompress bob.tgz, tar zxvf bob.tgz - If a folder was compressed originally, then the original folder will be created. If not, then the files will
be placed in the current directory.
If you just recieve a tar file for some reason, you can decompress that by using tar xvf bob.tar instead.
