There is. If you invoke just "su", you inherit (more or less) the (regular) user's environment, with some exceptions. If you invoke "su -" (or equivalently "su -l") you get a fresh environment for root, as if you had logged in as root directly. The gory details are in su's man page (a bit complicated by the fact that su can do more things, e.g. su'ing to another user instead of root, executing just one command as the new user, and so on). Jonathan commented on the other points much better than I could, so I'll stop here :-) regards - -- tomás -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlgqHj4ACgkQBcgs9XrR2kZyzwCfUtGS2LOYMjSZPiKpXjjVlVVe Fm8AniuuM5RYsEqJoz7Y7LDEePn5OBeR =DY4U -----END PGP SIGNATURE-----
