Well it is totally true in a pedantic sense, but you are correct in pointing out the effect of initialization files. They have the desired effect even though strictly the environment is not being inherited from an unrelated process, merely being recreated. > which is something that i should have stated when i first made > post of using ". /.bashrc". > > something that does come to mind is if i have 2 terminals open > and i change '.bashrc' in terminal-a and then switch to > terminal-b and issue an 'sh' command, i believe that the new > shell would/might inherit the environment of the shell i was > already in. but that is something that i would have to try > before i would say that that *is* what would happen. > [yes, i am too lazy to try right now to see. ;-) ] Of course it does.
