[comp.unix.shell] Overhead of raw-mode shells

steve@cs.uow.edu.au (Stephen Cliffe) (05/06/91)

Does anyone have any feeling for the overhead placed on a machine
by running the more modern shells that support command line editing. 

We would like to make either bash or zsh available to our students
and are a little concerned by the possible extra system overhead this
could impose due to the use of raw-mode and therfore conext switches
etc.

Thanks,

Steve.

The biggest problem with bash is it's size, its alot bigger than sh :-)
There are 3 of us at work who use bash and another using a real old ksh,
with no undue effects on our old '020 box.
