>Description:

When I execute the following script with /bin/sh
---------------------------
#!/bin/sh

alias l='ls -l'
val=lucid
case "${val}" in
l|lucid)	echo "lucid" ;;
esac
----------------------------
I get the error:
/home/filip/testsh: 6: Syntax error: word unexpected (expecting ")")

Apparently, the 'l' in the case pattern is expanded to "ls -l".
This is not what one might expect.

	See under 'Description'.

>Fix:
	
	Use pdksh, zsh, or bash instead
