Uncompressing a .tar.gz file on Sun’s release of tar

While trying to uncompress a tar.gz file, if you get a message something like this:

 
tar: z: unknown function modifier
Usage: tar {c|r|t|u|x}[BDeEFhilmnopPqTvw@/[0-7]][bfk][X...]

You are using a Sun’s release of tar and -z is not a valid option. Instead, try following commands:

 
gunzip file.tar.gz

You will get a tar file, run this:

 
tar xf file.tar

Cheers!
