Originalnachricht

Name        : mksh
Product : Fedora 20
Version : 50c
Release : 1.fc20
URL : https://www.mirbsd.org/mksh.htm
Summary : MirBSD enhanced version of the Korn Shell
Description :
mksh is the MirBSD enhanced version of the Public Domain Korn shell (pdksh),
a bourne-compatible 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, being a
bourne shell replacement, pdksh successor and an alternative to the C shell.
