Could you please tell what your sed has to say about it? It > works even on AIX 4.3.3. It says nothing. The result of "printf '%s\n' ./foo/bar | sed -e blah" is just wrong, (i.e. "./" remains). I stripped down to "sed -e 's|^\(\./\)*||'", does not work. Probably due to \( \) pair. Skimmed through sed manpage, seems no mention of bracket grouping. -- Duy
