How about the central server in my department?
$ tar -czf - /etc/passwd
tar: z: unknown function modifier
Usage: tar {c|r|t|u|x}[BDeEFhilmnopPqTvw@[0-7]][bfk][X...] [blocksize] [tarfile]
[size] [exclude-file...] {file | -I include-file | -C directory file}...
$ ls -l /usr/sbin/tar
-r-xr-xr-x 1 root bin 77920 Apr 20 2011 /usr/sbin/tar
This is Solaris 10, which is still shipping and which Oracle says it will
support until at least the year 2021. Solaris 11 added -z, but there are still
quite a few Solaris 10 hosts out there.
Also, AIX 7.1, the current release, has a tar that lacks -z. I can't easily
check HP-UX, but wouldn't be surprised if it's like AIX.
Feel free to add this to the comments.
