My google fu seems to fail me - or maybe it's just the delightful amount of fantastic information there is available on the IBM Power/iSeries/as400 beast.
In any case, I have a .tar.gz file on this machine.
When I fire up qsh and run tar -xzvf mytarfile.tar.gz it doesn't run 'cause there's no z flag. And tar -xvf tells me that the byte limit has been reached. A lot.
Is there a command somewhere on the iseries that I could use to actually untar my file?
gz is technically not a tar file - it's a gzip file. tar -z is a convenience on most *nix platforms that's missing on IBM i. The notional steps are gzip followed by tar. I have gunzip on my machine but it's been there so long I can't remember if it's part of the base OS or if I added it on.
