In bash the best way is:
if tty >/dev/null ; then
# run with a tty attached (from Terminal)
else
# run from Tracker
fi
You can also check for the TTY environment variable
If it's not present (getenv("TTY") returns NULL), then you
are run from Tracker or at least not from a Terminal.
Also note that Tracker always run programs with the
current working directory as $HOME
(that's why you see sometimes cd "`dirname "$0"`" in shell
scripts).
