How can i create a .bat file which can run ruby

Rails
1

Guys,
I have InstantRails in my PC. i have written a ruby programm which will
copy a file from my document to rails private directory varifying some
characteristic of files.Suppose ruby directory is
c:/instantsRails/ruby/bin/ruby.exe and my file is in c:/myfile.rb . so
how can i create a bat file which can run ruby and run my file? so that
each time when i copy file to upload directory and just click the .bat
file and do the job.

waiting for ur responce.

thanks for ur reply . but I tried it but error was

“ruby” command not found.
so i guess, i have to first run the ruby.exe and then then run the file
by ruby.

am I right? if yes then how can I do this?

Perhaps the path to your ruby.exe is not included in your PATH
environment variable in Windows. If so, either edit your PATH to include
it, or else add the full path to the ruby.exe to your batch file:

c:\InstantRails\bin\ruby.exe myfile.rb

[Your actual path may vary from that shown above]

I would guess that ruby isn’t properly installed…or not installed at
all,
apart from instantRails.

if you type “ruby -v” in a cmd you should get a line telling you which
version of ruby you have installed…

instantrails contains ruby so that rails applications can run in the
instantrails sandbox, but it does not install as a os wide
application/service…I’m out of my depth with the vocab. Basically, if
you
download and install ruby

http://rubyforge.org/frs/?group_id=167

it will install and you will be able to run ruby anywhere in a command
line.

This should help you, it’s from my .bat files that run ruby scripts. Of
course, fix the paths to match yours.

echo off cls

REM Set up the environment variables for the script
set PATH_TO_RUBY=D:\InstantRails\ruby\bin
set RUBY=%PATH_TO_RUBY%\ruby.exe
set PATH_TO_SCRIPTS=F:\Projects\autoscripts

%RUBY% %PATH_TO_SCRIPTS%\MyRubyScript1.rb
%RUBY% %PATH_TO_SCRIPTS%\MyRubyScript2.rb
%RUBY% %PATH_TO_SCRIPTS%\MyRubyScript3.rb

If you want it to be something that starts asynchronously (in the sense
that it starts in a separate Command window and does not hold up the
original .bat file which is starting your script, you could also use:

start %RUBY% %PATH_TO_SCRIPTS%\AnotherScript.rb

Hope this helps!
Cheers
Mohit.

The problem your are having is because of one of the features of
Instant Rails: the fact that it does not modify your system
environment. IR’s ruby\bin directory is not on your system path (as it
would be with a normal Ruby installation).

If you don’t plan to move IR at all (for example, you don’t have it on
a flash drive), then the simplest thing would be to put IR’s ruby\bin
on the path.

Another alternative would be to put your bat file in IR’s ruby\bin
directory and then at runtime use the path to the bat file to
construct a path to ruby\bin\ruby.exe. For examples of doing this,
look at the bat files already in the ruby\bin directory.

thanks for clarifying that for me as well!
