How can I extract or uncompress a file from tar ball downloaded from the Internet under Linux using bash command prompt?
You need to use the tar command to extract files from an archive or to create an archive (also known as tarball). A tarball or an archive is nothing but a single file that contains various individual files. It also includes information which allows your to restore files to their original form by one or more extraction programs such as tar command.
Extract or Unpack a TarBall File
To unpack or extract a tar file, type:
tar -xvf file.tar
To save disk space and bandwidth over the network all files are saved using compression program such as gzip or bzip2. To extract / unpack a .tar.gz (gzip) file, enter (note -z option):
tar -xzvf file.tar.gz
To extract / unpack a .tar.bz2 (bzip2) file, enter (note -j option):
tar -xjvf file.tar.bz2
Where,
- -x : Extract a tar ball.
- -v : Verbose output or show progress while extracting files.
- -f : Specify an archive or a tarball filename.
- -j : Decompress and extract the contents of the compressed archive created by bzip2 program (tar.bz2 extension).
- -z : Decompress and extract the contents of the compressed archive created by gzip program (tar.gz extension).

Thanks for the info.. I dont know how many times I’ve come here to find this one simple command, but I dont seem to be able to memorize it!! This time, I THOUGHT I had it, and did:
tar -xfv file.tar
So – I had it right, except for the order of the options.. Shouldn’t this have worked? It didn’t, and I’m not clear why..
The -f option has to come last, to tell tar what the filename is.
