How can I make my script run directly on the command line in windows  
like ruby is?  
ruby -w myscript.rb -o  
myscript -o

If you’re using one of the latest one-click installers, this should  
already work for you. Here are some things to check.

# make sure the path to ruby.exe is in your path system environment

variable  
C:\>path  
PATH=c:\ruby\ruby186\bin;C:\WINDOWS;C:\WINDOWS\System32\Wbem

# make sure .rb and .rbw are set in the pathext system environment

variable

# if you need to change a system environment variable, make sure you

# set it in the gui, and not with the set command. Otherwise the

# changes won’t persist.

# Here’s some info on how to do that:

C:\>echo %pathext%  
.COM;.EXE;.BAT;.CMD;.RB;.RBW;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.tcl;.PSC1

# make sure the file associations are there.

C:\>assoc .rb  
.rb=rbFile

C:\>ftype rbfile  
rbfile=c:\ruby\ruby186\bin\ruby.exe “%0” %\*
