>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'.

Use pdksh, zsh, or bash instead
