How to use SVN commands from command line?

I am able to check out projects from SVN repository using eclipse as in the below screen shot.

But i am not able to do the same from command line..I am getting the error as : 'SVN' is not recognized as an internal or external command

If SVN is not installed on my machine how 开发者_运维知识库come eclipse is able to checkout?

Do i need to install SVN client in my machine?

I tried searching on my machine but could not find which path(SVN installation) eclipse is referring to execute SVN commands

Subclipse is coming with its own SvnClientAdapter which implements the Subversion API.

Subversion itself provides a default UI, in the form of a command line interface. If you want to easy operate with it on the Windows console, then you should add the Subversion home to the PATH environment variable.

Apart from that I prefer in most cases to use TortoiseSVN on Windows.

You should install the command line client yes. For help on that see svnbook
