Linux.com offers another tutorial on their favorite topic, the shell.
When you're at the CLI, you're where it's at. Why else would Microsoft -- the glutton for GUI -- be slaving so feverishly to add a shell to their next release? At the risk of sounding like Yogi Berra and that duck in the barbershop commercial, I've got to say although Microsoft found replacing the DOS command line to be too tough a shell to crack, others did not, and that's why Monad is no longer on the feature list for Vista. Never fear, gentle readers, Linux has shells enough for all, and this week we'll look at two different ways to change the one you're using.
The most popular shell on Linux distributions is the Bourne Again Shell, aka bash. SUSE 9.3 Professional also includes Zsh, which resembles the Korn shell; tcsh, an enhanced, compatible version of the Berkeley UNIX C shell; and sash, a stand-alone shell with built-in commands.
Not included with SUSE, but readily available on the Internet, are the Clam Shell, whose functionality can be defined at runtime; the Perl Shell, for those who just can't leave /home without a little Perl; and finally, one of the featured tools for this week, vfsh: the shell for those who can never decide which shell to run.
