Re: checking link files - recursive search

I'm assuming you meant for this response to go to the list, so I'm
replying there.

function resolve_recursive {
  (
    while :; do
      cd $1:h
      local file=$1:t
      file=$(stat -L +link $file)
      if [ -z "$file" ]; then
        echo $PWD/$1:t
        break
      fi
      argv[1]=$file
    done
  )
}

The cd's are the simplest way I could think of to handle symlinks
using relative paths to different directories.  The enclosing '(' and
')' make the entire function execute in a subshell, so that your
actual PWD isn't modified.  When it resolves the file completely, it
prints out the absolute path to it and exits.
