mksh 29.6-2 (i386 binary) in ubuntu gutsy

 mksh is the MirBSD enhanced version of the Public Domain Korn
 shell (pdksh), a bourne-compatible and loosely POSIX compliant
 shell which is largely similar to the original AT&T Korn shell.
 It includes bug fixes and feature improvements in order to produce
 a modern, robust shell good for interactive and especially script
 use; emacs mode command line editing and input/script processing
 have been made UTF-8 safe.
