I realize I may be opening a can of worms, but as I agree with you on the usefulness of csh(1), why do we continue to use csh as the default shell being that I'd hazard most sane mortals use sh or bash? I would definitely prefer to have both sets of instructions, but honestly given one line needs to be changed ever so slightly, it would look silly to reproduce the entire script multiple times with only that change. If you prefaced the script with "This script is optimized for csh, see below for other shells" and then just list the optimal way to export env. vars. for the other popular shells. D=/foo;export (sh) export D=/foo (bash) -E- Giorgos Keramidas wrote: > On 2005-10-26 13:38, "Eli K.
