may not know it, there's a world of power available
at the lowly command prompt. One of the most
powerful command line interfaces is the Korn
Shell. In Learning the Korn Shell the
authors have attempted to present Korn's power
and flexibility in a manner that even the most
die hard GUI user should find compelling.
authors don't spend much time with fluff either.
The book weighs in at 412 numbered pages, with
336 of them being direct explanation and samples
of shell use. The reading is easy for those new
to a command line shell, while not being condescending.
Experienced Unix shell users will find it an
excellent resource for creating sophisticated
first three chapters cover the basics and Unix shell history.
They include information on Unix file systems, how input and
output (I/O) works in Unix, command line editing and customizing
the Unix environment.
four through nine cover programming with the shell. I mean
just the shell - not perl, not php, not python, just the Korn
shell itself. It's amazing what a user can do with no more
than the command line and scripts.
last chapter is mainly for Unix administrators. It details
how to set up the Korn shell as the default shell along with
customizing the environment and editing modes. There's also
about seven and a half pages on making shell scripts more

you are used to using one of the other myriad shells available
for Unix/Linux then you will want to read Appendix A. It compares
features of the major shells with Korn and references chapters
in the book to illustrate Korn's differences.
your flavor of Unix doesn't come with the Korn shell, Appendix
C shows you how to get it. There are URLs showing where to
go and a table showing what types are supported. Linux is
there of course, along with versions for Solaris, MVS, AIX
and even Unixware.
back of the book contains a removable quick reference. It
contains a good listing of the shell's control commands, built
in variables, expressions and commands.
is a must read for folks using Unix/Linux. Even if you can
never imagine yourself using the command line, you will find
that the power inherent in the Korn shell will allow you to
do things the GUIs either can't do at all, or at best only
manage with lesser functionality.
