You could try this:
Code:
#!/bin/sh
#
#	Vars & Functions
#
	MENU="memory space ip user"
	memory () {
		free -m
	}

	space () {
	    df -h
	}


	ip () {
	    arp
	}


	user () {
	    whoami
	}
#
#	Menu
#
	if [[ -z $1 ]]
	then	echo "Select which info to display"
		select ENTRY in $MENU;do break;done
	else	ENTRY=$1
	fi
#
#	Execute
#
	$ENTRY

Hope this helps

NOTE:
This only works as long as the menu entry to choose from is named identical as the function to execute
