Of course, all this would be generally much better done in a

What's sad here is that we actually think this is interesting.
Bah, found another fault ...

Not all symlinks have absolute targets, and therefore we'd have to add
the dirname of the link to the target when doing the next lookup.
#!/bin/bash
candidate=`which $1`
while [ -L "$candidate" ]; do
ls -lh --color $candidate
DN=$(dirname $candidate)
candidate=$(stat -c %N $candidate|cut -d\` -f3|cut -d\' -f1)
if [ "$(basename $candidate)" == "$candidate" ]
then candidate="$DN/$candidate"
fi
done
ls -lh --color $candidate
Good. Well spotted.
I like the style, used by you:
variable=$(executable args)
Better than my:
variable=`executable args`
