Wrong list ? I like the idea, but your patch adds two subprocess invocations to the shell startup path. Each one takes ~200ms, and we can't afford to add any more. Instead of examining the group list, you can use something like local isadmin=3D0 [[ -w / ]] && isadmin=3D1 or local isadmin=3D0 [[ -w /cygdrive/c ]] && isadmin=3D1 Of course, that test assumes that only "administrators" can write to the drive root, and that's an imperfect proxy for administrative rights. You get the idea though: try to perform the test in pure bash code. --------------enig113BB274DF61EB57B9905373 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (Darwin) iEYEARECAAYFAk20kzsACgkQ17c2LVA10VtmggCdG8jOuqiLYTjBwo948VYYidym LVIAoMc7UnMeu/DTy4ctrcORzKymQQiX =C86B -----END PGP SIGNATURE----- --------------enig113BB274DF61EB57B9905373--
