creating new directory

Hi Salman,

Which course is this for?

If you're looking to create a folder on the command line you can use the mkdir command.

Example: mkdir foldername

this is for ruby and rails simple application i know that command but after installing ruby and rails kit what would be the first step for me to do .i am using windows not mac

Once you've got ruby and rails installed you need to generate the rails application using the following command.

rails new treebook

Check out this video :)

thanx but i have seen that video so many times but still i don't get what to do with .let's say i ave installed ruby and rails then what would be next step where should i go and what should i open

Hi Salman,

Open up your command prompt and use the cd command to move to the folder that you would like to create your application in.

Now use rails new treebook to generate the application. Once that command finishes you should have a new folder in the directory called treebook. Use the command cd treebook to move into the new folder. Now use the ls command to see a list of all the new files and folders that have been created.

You can now open up the treebook folder in your text editor to take a closer look at the files, or just continue on with the course. Make sure that you are in the treebook folder when you issue the git commands in the next video.

you know what i have managed to create new directory but when i write rvm use 1.9.3 it 's says 'rvm' is not is not recognized with internal or external command what should i do now

RVM is only available for Mac/Linux.

If you have already installed ruby you should be okay skipping the rvm steps.

If you want to be able to manage multiple versions of Ruby on Windows take a look at pik.

That's great thank you I will try it

now i have generated application but when i type that http://0.0.0.0:3000 in browser window it comes up with nothing

A few notes using Ruby on Rails on Windows ...

• To start Rails type rails s
• Then open up your browser to: 127.0.0.1:3000
• To stop the Webbrick server use CTRL-Break

Both the rvm and 0.0.0.0 only apply if you are working on a Mac.

everthing is working fine and getting along with project ,,,thanx guys ,,,,,,does any one know how to create an ordering system in ruby and rails with shopping cart
