FFS. The gzip folks are back to this hubris? When it first came out they tried to usurp the .Z (compress) file extension unstead of using a nonrude '.gz' as they were quickly convinced to. Please use "gzcat"; "zcat" is for compress/uncompress and if your vendor's installing gzcat as zcat they need a fresh complaint. Assuming the OP is on a modern Fedora box, let see what I have on my system here... $ cat /etc/redhat-release Fedora release 30 (Thirty) $ echo "test" > test.txt $ gzip test.txt $ gzcat test.txt.gz -bash: gzcat: command not found $ zcat test.txt.gz test $ sudo dnf provides gzcat Error: No Matches found $ sudo dnf provides zcat *gzip*-1.9-9.fc30.x86_64 : The GNU data compression program Repo : @System Matched from: Provide : /bin/zcat Filename : /usr/bin/zcat ... Nope, it's zcat, even for gzip files, on modern Linux systems ( at least Redhat based ones ). I've not used gzcat since I retired my last Sun box over 10 years ago. - Derrik -- -- Derrik Derrik Walker v2.0, RHCE dwal...@doomd.net "Those UNIX guys, they think weird!" -- John C.

Also, for future reference, gunzip behaves as a filter if you don't supply a filename. So: gunzip < thing.dd.gz | dd ... and no zcat/gzcat special command usage required.
