I checked my RH5.1 system and found that $USER, $USERNAME, and=20
$LOGNAME are set automatically. I found the following script to be=20
fast and reliable:
#!/bin/sh
=20
if [ $USER =3D "jdoe" ]; then
echo "jdoe is logged in."
elif [ $USER =3D "root" ]; then
echo "The Head Honcho is logged in."
else
echo "Some peon is logged in."
exit 1
fi
