Hi all:
How to know if I'm using an xterm or a gnome-terminal from

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

HTH,

Thanks to all that answered my question with a lot of useful
suggestions.
Finally, I decided to use Nalin's suggestion and implement the
following
command to know if I'm using an xterm or a gnome-terminal:
xprop -id $WINDOWID WM_CLASS | awk '{print $3}' | sed 's///g'
| sed
's/,//g'
which returns either xterm or gnome-terminal.
for me xprop -id $WINDOWID WM_CLASS returns WM_CLASS: not found.
This is on F11, Gnome terminal 2.26.1.
?
In my case it is Fedora 12 and gnome-terminal 2.28.2

The parent of the shell may not be the terminal. You could check, and if the parent is xterm run in the terminal. if it is anything else, start it in a new xterm. You will then get a new xterm if people are logged in remotely or escaping out from some other app. Perhaps you can live with that? birger -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines

Have the script start the xterm:
: ${have_xterm:=}
[ -n $have_xterm ] || exec env have_xterm=1 xterm -e $0 ${1+$@}
Self starts in an xterm. Untested.

Germán.
What about something like this in your script?
PARENTPID=$(ps -o ppid -p $PPID | tail -n1)
ps u -p $PARENTPID | grep xterm { echo Yes!; } || { echo no; }
The first line gets the parent of your script's parent process (so
bash's parent). Then the second line prints out the information based on
that pid, which is what you're testing against.
If there are more levels in between, this doesn't work the way it is,
but you should be able to easily scale it to a loop which keeps going
either until it hits an xterm process or hits init (as a last resort.
Maybe there are better conditions you could figure out).
