How to unzip/extract a .tar.gz file in linux?

Type man tar for more information, but this command should do the trick:

tar -xvzf community_images.tar.gz

To explain a little further, tar collected all the files into one package, community_images.tar. The gzip program applied compression, hence the gz extension. So the command does a couple things.

• f: this must be the last flag of the command, and the tar file must be immediately after. It tells tar the name and path of the compressed file.
• z: tells tar to decompress the archive using gzip
• x: tar can collect files or extract them. x does the latter.
• v: makes tar talk a lot. Verbose output shows you all the files being extracted.
