OpenBSDs ksh for GNU/Linux

What is it?

The OpenBSD people have cleaned up and enhanced the original PD ksh with great features. E. g.

PS1=`\u@\h'

works like under bash (try this with a standard PD ksh).

So I ported the OpenBSD version of ksh to GNU/Linux.

What's new?

In Version 0.4.1 from 27.08.2010

Fixed a bug regarding building with older glibc and ISOC99

In Version 0.4 from 23.08.2010

Sync'ed with ksh from OpenBSD 4.7
Ported to GNU autotools (no more BSD make/pmake dependency to build, hooray)
replaced strlcpy with strncpy and strlcat with strncat (no strlcpy/strlcat in GNU glibc)
documented changes in oksh.diff

In Version 0.3

Synced with latest OpenBSD CVS
Licensed under GPLv3

In Version 0.2

Removed all code from MirOS's mksh because of license problems
Removed internal mknod builtin command. Even in the OpenBSD CVS it is mentioned that a builtin mknod is against unix philosophy, so I fail to see the point in this.

Download

Here are the sources and md5sum. To build and install use the usual ./configure && make && make install.

There is a PKGBUILD for Arch Linux

FAQ

Cursor keys for scrolling through the history aren't working

Do you have EDITOR variable set to vi,vim or something similar? Then ksh switches to vi mode, where this feature isn't available. Do "set -o emacs" in your .profile, and it should work like you're expecting
