First it is DISPLAY not display.

export DISPLAY=ip_address_or_hostname:0.0

Many people care more about "DISPLAY" than
they do about "display".

What are you trying to do?

[Torsten.]

everything is case sensitive in this OS.

"display" is not equal to "DISPLAY".

# echo $DISPLAY

[ng_7]

Sorry , my mistake, after i change to the below command, still error.

echo $DISPLAY
sh: DISPLAY: Parameter not set.

[Steven Schweda]

You already have one good suggestion for how
to set it. If you need more than that, you
may need to explain what you're trying to do.

If you're sitting at a VT100 terminal, the
DISPLAY setting may not matter much. What
_are_ you doing? Sitting at an HP-UX
workstation? Sitting at a Windows system?
Sitting at a Macintosh?

If it isn't set, you must export it like Clay suggested.

This thread has some info how to automatically set it up from who(1):

hi,
Unless you explicitly set your DISPLAY environment variable, the output of echo $DISPLAY will always give you message "display: Parameter not set."

You can set your display either in your .profile:
e.g.
export DISPLAY=localhost:0.0

or to another host that is running/emulating the X-display:
e.g.
export DISPLAY=Server_with_graphics_display:0

hope this helps!

kind regards

Hi,

Type the command: set

Then you see all your variables.

>Bob: Type the command: set

These are not the droids you want. :-)
The correct comand is env(1), for exported variables. Or typeset -x.

You could set the display variable automatically in one of the files which is processed by the login process.

Which file to edit
******************
- depends on which shell you are using.
Use command: finger username
to see which shell you are using.
Then read the man pages for this shell to see which files to edit.

To obtain the host/ip information you could use the command: who -Rm

example:
export DISPLAY="`who -Rm|awk '{print $6":0.0"}'|tr -d '()'`"

or
setenv DISPLAY "`who -Rm|awk '{print $6":0.0"}'|tr -d '()'`"
