I will just jump in her long enough to say that using 'env' like that is the idiomatic way to avoid differences in shells between sh and csh (and therefore between bash, dash, posh, ash, ksh, mksh, zsh, and I think you get the idea). It is a way to guarentee the ability to set variables regardless of shell. This make documenting things easier. Bob
