just a small security note:
Your use of set here is quite dangerous, because $SSH_CLIENT may contain
paramters to set! For example, if SSH_CLIENT is "-n", this script will not
do anything after the set command - and if you put it in your ~/.profile
or something, you'll not be able to do anything with the shell :)
the solution recommended since antiquity (e.g., Kernighan & Pike's "The
Unix Programming Environment", 1984) is to do something like
set x $SSH_CLIENT
export DISPLAY=$2:0.0
or even
set x $SSH_CLIENT; shift
export DISPLAY=$1:0.0
note that none of these forms work in zsh, which changed the way whitespace
is processed in commands ("$SSH_CLIENT" is treated as one word). The
modern method is to use "%%": (see manual of bash or zsh for more information)
export DISPLAY=${SSH_CLIENT%% *} # don't remove the space before *
