First Example Rexx Exec

In the previous Blog, I described how to install and customize the Regina Rexx interpreter for Mac OS X Snow Leopard.  Any comments or installation instructions are based upon that blog.

Today, I thought I'd share a short exec that I use in place of the LS command.  Coming from a Windows/DOS world, I kind of missed my DIR command.  This seems like a reasonable replacement.  Hope you find it useful!


#!/usr/bin/regina
address SYSTEM "ls -le" with OUTPUT STEM wdir.
if rc = 0 then do l = 2 to wdir.0
   say wdir.l
end
address SYSTEM "pwd" with OUTPUT STEM wdir.
if rc = 0 then do
   say
   say "Current directory is:" wdir.1
   say
end
exit 0

Save the above text as ~/Shells/dir then issued the terminal commands:

cd ~/Shells
chmod u+x dir


Once done, you can simply type in DIR, just like good old DOS and see the directory listing.  Below is the output when using DIR to list my home directory:
