Whitespace in command alias
This function should get you started:
good () {
if [ -z "$1" ]; then
echo "Perhaps you meant 'good night'?"
else
if [ "$1" = "night" ]; then
echo "GOOD"
echo "NIGHT"
echo "good"
echo "night"
echo "etc"
else
echo "ERROR: strange time detected: $1"
fi
fi
}
Save it as, for example, good.sh, then source it:
. good.sh
good night now will execute various commands (replace the echo statements with whatever you want).
