Re: Am I running under X?

[Eric D. Hendrickson]

Write a script something like this, and call it "screen".  Or call it
"myscreen".  Or whatever...

#!/bin/sh

# if no DISPLAY variable, then we are not in X

# DISPLAY might not be the best environment variable to test for but
# it should work

if [ -z "$DISPLAY" ]; then
  exec /usr/bin/screen blah
else
  exec /usr/bin/screen blah2
fi
