I had a question regarding the various shells performance. In "The Korn Shell
Command and Programming Language", by Bolsky and Korn it is stated:
"In spite of its increased size, ksh provides better performance. Programs
can be written to run faster with ksh than with either Bourne shell or the C
shell, sometimes an order of magnitude faster."
Does anyone have some good examples of this statement? I know doing arithmetic
now in the ksh is much better because it is builtin, but what about in general?
Responses may be posted or e-mailed to me directly. I will post a summary of
