svn co http://localhost/testsvn
localhost - is the server name or ip in which the svn repository is running.
testsvn - is the project name.

The following files will be downloaded from 'test1.txt' using checkout cmd,
- folder named 'testsvn'.
- a file inside the testsvn folder named 'test1.txt'.
- svn folder inside testsvn containing all the repository and revision details of the files.

From the above cmd, the files inside 'testsvn' were checked out.

2) add SVN Command

add command is used to append a new file in to the server.
Usage:
svn add <filename>
