What shell should I use on helix?
The Unix operating system has several flavours of command interpreters
which will affect the behaviour and appearance of your helix session.
New users are set up with the 'T-shell' (tcsh) by default, which
has useful features such as file name completion and command line
editing. Other shells you could choose to use are ksh, sh, and csh.
To change your default shell, send a
ptr to the helix staff.
For more information on any shell, type 'man shell_name' at the
helix prompt.
