it depends on invocation (and thoug is intentional): you may set a complete su-environmen with "su -" or just change your effective user id with "su", see "man su" > 2) newgrp unsets the HOME environment variable. huh, what's that? that makes me wonder.. moment, i'll check. manpage says your current environment is kept, which it actually doesn't with $HOME. doing "newgrp -" (as you also do with su) reinitializes your env and there you go with $HOME. i guess: newgrp starts a new subshell and when $HOME is not exported, you loose it in that subshell unless you force reinitialisation. seemes to be intentional as with su. gerhard
