I don't think either of a/src, b/src, or x/y/dataLu/src is an absolute path; they all start downwards from your current working directory, $PWD.


Just in case neither the readlink nor the realpath solution please you, and you don't want external commands but bash builtins do the job for you, how would something along this line fit in:
Code:
DIR="../../dataLU/src"
TMP="${PWD%/*}${DIR#..}"
TMP="${TMP/*..*}"
ls "${TMP:-${PWD%/*/*}${DIR#../..}}"

Unfortunately, shell's "parameter expansion" only works on one variable at a time, so the repeated assignments to temporary variables are inevitable. Still it will be faster than creating a process plus loading and running any extermal command.

SHTOOL-MKLN.TMP(1)					      GNU Portable Shell Tool						SHTOOL-MKLN.TMP(1)

NAME
shtool-mkln - GNU shtool enhanced ln(1) replacement SYNOPSIS
shtool mkln [-t|--trace] [-f|--force] [-s|--symbolic] src-path [src-path ...] dst-path DESCRIPTION
This is a ln(1) style command. It is enhanced to provide automatic calculation and usage of relative links with the shortest possible path, if possible. Usually if src-path and dst-path are not absolute paths or at least they share a common prefix except the root directory (``"/"''). When more than one src-path is specified, all of them are linked into dst-path. OPTIONS
The following command line options are available. -t, --trace Enable the output of the essential shell commands which are executed. -f, --force Force the creation of the link even if it exists. Default is to fail with error. -s, --symbolic Create a symbolic link instead of a hard-link. EXAMPLE
# shell script shtool mkln -s foo/bar baz/quux HISTORY
The GNU shtool fixperm command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for ePerl. SEE ALSO
shtool(1), ln(1). 18-Jul-2008 shtool 2.0.8 SHTOOL-MKLN.TMP(1)
