What about this:

$ perl -e 'use Cwd "realpath"; (-e "/does/not/exist") ? print 
realpath("/does/not/exist") : print "/does/not/exist"; print "\n"'
/does/not/exist

$ readlink --canonicalize-missing /does/not/exist
/does/not/exist



$ ll /tmp/xxx
lrwxrwxrwx 1 albinus smc3 13 08-14 09:20 /tmp/xxx -> /home/albinus/

perl -e 'use Cwd "realpath"; (-e "/tmp/xxx") ? print realpath("/tmp/xxx") : 
print "/tmp/xxx"; print "\n"'
/home/albinus

$ readlink --canonicalize-missing /tmp/xxx
/home/albinus

Best regards, Michael.
