unzip tarball files:

usually to unzip a *.tar.gz file i used 'tar' command. The syntax of the tar command is:

Syntax:
tar -option file_name.tar.gz

tar -xzfvp file_name.tar.gz
the above command will unzip a tarball file.

but when i tries to unzip it says error 'vp can not open file', so am unable to unzip a file. Then i found a alternative command to unzip a tar.gz files. Its gzip command i command i used to unzip my tarball. The command i used is as follows:

gzip -dc file_name.tar.gz | tar xf -
