Porting to OS/2: Install sh

Available sh on OS/2 are at least three ones. They are pdksh, ash and bash. I recommend to install them all, but to use pdksh mainly. Because it's the fastest among them and supports some interesting features such as extproc of OS/2. However, some unix shell scripts require bash explicitly. And some scripts are happy with ash. So if you have some problem with pdksh, then use ash. But I've not encountered this situation so far. ^^

Use mksh instead of pdksh. mksh is a successor of pdksh, and maintained actively.

1. pdksh

You can get pdksh from

http://hobbes.nmsu.edu/download/pub/os2/util/shell/pdksh-5.2.14-bin-4.zip

Copy ksh.exe and sh.exe into x:\usr\bin. And copy sh.exe into x:\bin, because unix scripts require /bin/sh.

You can get newer versions of pdksh from hobbes.

2. ash

You can get ash from

ftp://ftp.netlabs.org/pub/gcc/alpha/ash.zip

Copy ash.exe into x:\usr\bin.

ash.exe was built with kLIBC, so you make sure that kLIBC runtime in your LIBPATH. Otherwise, copy x:\gcc\usr\lib\libc*.dll into x:\usr\dll. Of course, make x:\usr\dll directory first if it does not exist.

And I recommend to rename \OS2\PRINT.COM to other, because configure scripts of autotools use 'print' expecting to print a message to screen, but PRINT.COM does not work so.

3. bash

You can get bash from

http://homepage1.nifty.com/jsawa/os2/gnu/bash-3.2.zip

Unzip OS2tree.zip from the zip into x:\ in order to install its contents into x:\usr.

• unzip OS2tree.zip -d x:\

And x:\usr\dll to your LIBPATH in CONFIG.SYS.

4. mksh

You can get mksh from

http://hobbes.nmsu.edu/h-search.php?key=mksh&pushbutton=Search

Copy mksh.exe into x:\usr\bin.
