I seem to have constructed a solution to my own problem. I wrote a
function that creates the desired behavior for me and saves it in
$expanded if the argument was in fact an alias.
function expand_alias() # expand an alias to full command
{
if [ "$1" = "." ]; then
argument="\\$1"
else
argument="$1"
fi
match=$( alias -p | grep -w "alias $argument=" )
if [ -n "$match" ]; then
expanded="`echo $match | sed -e s/[^=]*=// | sed 's/^.\(.*\).$/\1/'`"
else
expanded="$1"
fi
}
Thanks,
Justin
