Ticket #43 (new enhancement)

Description

We would like to be able to specify that a command could have 1 or 2 parameters.

For example, this configuration requires that 2 parameters be specified:

prtvtoc /usr/sbin/prtvtoc $1 $2;

This one won't allow a second parameter:

prtvtoc /usr/sbin/prtvtoc $1;

I'd like to be able to allow users to specify either 1 or 2 parameters. e.g. the following should both be acceptable:

• prtvtoc /dev/rdsk/c1t0d0s2
• prtvtoc -h /dev/rdsk/c1t0d0s2

Perhaps with a syntax like this:

prtvtoc /usr/sbin/prtvtoc $1 $2?;

or this:

prtvtoc /usr/sbin/prtvtoc $1 [$2];
