Description John Mazzitelli 2009-03-10 13:01:00 UTC
If readlink does not exist, we could recursively parse the output of ls -ld which, for symlinks, has the form "name ->  target".

Note that we don't want to assume /usr/bin - I would just leave those full paths out and assume that $PATH points to ls, expr, and dirname (since there might be those people that have those in /bin or /usr/local/bin or wherever).

# Resolve symlinks.
while [ -h "$PRG" ]; do
     ls=`/usr/bin/ls -ld "$PRG"`
     link=`/usr/bin/expr "$ls" : '^.*->  \(.*\)$'`
     if /usr/bin/expr "$link" : '^/'>  /dev/null; then
       prg="`/usr/bin/dirname $PRG`/$link"
     PRG=`whence "$prg"`>  /dev/null 2>&1
     APPHOME=`/usr/bin/dirname "$PRG"`
