problem while doing gzip over ssh

I am getting below error while running gzip command over ssh
ssh 123@HPUX "gzip"
ksh: gzip: not found

whereas if i am running tar in same way it is working properly.
ssh 123@HPUX "tar"
tar: usage tar [-]{txruc}[eONvVwAfblhm{op}][0-7[lmh]] [tapefile] [blocksize] [[-C directory] file] ...

Can you please suggest why am i getting this error and how can i overcome this problem ?

When i tried following step gzip is working properly
ssh 123@HPUX
gzip
gzip: compressed data not written to a terminal. Use -f to force compression. For help, type: gzip -h which means that gzip is working.

Your $path may be set differently for an interactive login session, versus executing a single command via ssh. Does it work if you specify an absolute path to gzip? Try logging in interactively, and use the command which gzip to show where the binary is. Perhaps it's something like /usr/local/gnu/gzip . (You might want to do echo $path too, and make a note of it for comparison purposes.) Then try using that path in your batch SSH command, i.e. ssh 123@HPUX "/usr/local/gnu/gzip" to see what happens. The command ssh 123@HPUX 'echo $path' (note single quotes!) should tell you how your $path is set in that context -- if you compare that to your interactive $path, you'll probably see a difference that explains why gzip isn't found in the first version of your batch command.

Wild guess: it's ksh raising the error the first time. When you do a full ssh login, are you using ksh? Are you running any scripts that modify its path?
