Most Mac users would have little use for the Korn shell but it is very useful for someone who knows how to script and who uses their Mac as a server. Mac uses their own version of FreeBSD (http://www.freebsd.org/) called Darwin. You can google Darwin to find out more. I use Linux as a Desktop and as enterprise servers. It is nice to use the Korn shell to scan images, determine their size and resize or compress them on the fly. You can install Image Magic on your Mac OSX and have many of your photoshop commands on your command line. You can control your DVD/CD burner and scanner by the command line using scripts to manage, backup and do custom tasks. So, you may never use it but it is far from obsolete. $ convert Version: ImageMagick 6.0.3 07/20/04 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2004 ImageMagick Studio LLC Usage:

Specify 'file' as '-' for standard input or output.
