Since we haven't been told what operating system is being used in this case, there isn't any way for us to check the man pages for that system to see if
-z option is required when extracting files for the OP's system. The standards require
pax to do this, but no longer require that
cpio and
tar even be present on conforming implementations. Although the standards never required that any of these utilities produce or process compressed archives, I don't remember seeing any version of
pax that has options to produce a compressed archive that needed to be told that that archive was compressed when extracting files from it.

Hi,
I'm using a tar command
tar -xOvf /home/mytar.tar
