Hi all:

How to know if I'm using an xterm or a gnome-terminal from command line?

The output of "echo $TERM" is "xterm" from both of them.

How to know?

Cheers,
Germán.

Run

ps axlw | grep term

This will show you which one you are running

But if there are several xterms and gnome-terminals running, I'll get
them all. Which I want to know is the one I'm using.

Well, it looks as though gnome-terminal sets $COLORTERM, whereas xterm
doesn’t. But xterm doesn’t unset it, either, so if you get a user
starting up a gnome-terminal, thinking “Yuck!�¹ and using that
gnome-terminal solely to run xterm, then the xterm will inherit the
$COLORTERM setting.

Xterm has its own $XTERM_ variables, so you could test for those. But
gnome-terminal doesn’t unset those, either, so you could get a user
starting up am xterm, thinking “Yuck!�¹ and using that xterm solely to
run gnome-terminal…

And then you’re going to get someone using Konsole.

What are you trying to do?

It may do.

It may show which ones you are running, or which ones other users on the
same machine are running.

And (which I should have thought of in my last email, too) it’s quite
possible that the terminal and the shell script are running on different
computers (think ssh). Not all the variables will carry across the SSH
link.

So you either have to run with an 80% solution, think up some other way
of doing what you want, or trying to write a script that doesn’t need to
know the difference.

Good luck!

James.

I'm running a program called IRAF to work with astronomical images, and
it needs to use the graphic capabilities of an xterm, not
gnome-terminal. So, I'm trying to make a very simple script to start
IRAF, but first I have to know if I'm on an xterm (so it enters directly
to IRAF) or a gnome-terminal (in this case the script must open an xterm
before).

$ set | grep term
COLORTERM=gnome-terminal
TERM=xterm

James Wilkinson already outlined why most environment variables probably
shouldn't be trusted, so I'll suggest checking the output of
xprop -id $WINDOWID WM_CLASS

HTH,

This must be too easy, but I'm going to say it anyway.* Why not always start xterm and run IRAF within it?

If you were a pirate, you know what would be the one thing that would really
make you mad? Treasure chests with no handles. How the heck are you supposed
to carry it?!

Yes, I can always do that, but I want to make the script also ;-)
