Re: how do I use gunzip with dd?

["Derrik Walker v2.0" <dwalker@xxxxxxxxx>]

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.
