Shells have a variety of tasks, but their main purpose is to interface for users. Shell scripts are used for small, common-type tasks, but for anything extensive I would use perl or C, because there is no real enhancement for shells as far as programming goes, that's why most people choose c/c++ because of the speed and optimization. Actually I use perl over shell-scripts most of the time because of it's speed and routines built into the language. Shells aren't used for graphics. Look into tcl-tk or perl-tk and the X11 libraries for help with that. Dennis > On Fri, 27 Jun 1997, dpk wrote: > > > Shells are command interperters to the kernel.
