Hi,
I am using BASH and I define vi() function to start gvim GUI
program. This works great when I work on my Linux machine, but when I
log in remotely, it errors out saying "can not open display". I have
to un-define vi().

Is there a way I can know that I am working in a text mode in the
vi() to start vim in certain mode?

Thanks.

Check whether the environment variable DISPLAY is defined.

I think if you have xterm software then it should be supporting GUI

% which xterm
/usr/bin/xterm

If X you're not logged in through X windows, /usr/bin/xterm will still
be there, but the GUI is not available.

To the OP: how do you login remotely? If you use ssh with X windows
forwarding, vim should still work.
