This is the default for that particular user-- the shell that is opened up on a terminal when the user logs in. The default I was talking about is the default that the system uses in general- it is usually called sh, but most systems have /bin/sh pointing to some other shell which also has the same commands as the classic sh shell (such as bash). Writers expect sh to comply with certain standards so for example /bin/tcsh would not be a good thing for /bin/sh to point to because thestructure of tcsh is very different from the old sh. > If it is bash and there are other shells installed, you can > change the default shell. > chsh -s /bin/dash > or > chsh -s /bin/sh > or whatever. That will change your own particular shell that is brought up when you log in. Actually the latter will probably give you bash anyway, since /bin/sh is often a link to /bin/bash. >
