The command:
tar c DIR | compress >DIR.tar.Z
which works on a Debian-based Linux, fails on SunOS.
Why?

What is the default place for the output on SunOs? It it to tape or to stdout?– HennesMar 3, 2015 at 17:57

6When asking about a command that failed, you need to explain exactly how it failed. Was there an error message? What was it? Was an empty file created? A file with the wrong data? Did your computer explode? Please edit your question and clarify.– terdonMar 3, 2015 at 18:02

Traditionally, tar tries to write to a tape device (/dev/rmt0 or such) if an output file isn't specified.
Default-stdout is a GNU tar change, but SunOS is not Linux and usually does not use GNU userspace; it's a bit more… traditional. Thus you need tar cf - DIR instead.
Maybe the compress command is not installed on the SunOS System.
I used the following command to zip files from SunOS:
tar cf - | gzip >myzip.zip
Because, systems may both be unixoid but linux is not SunOS is not HP-UX - although all have tar commands.
