Creating SVN for Existing or New Project

Step 1: Create a directory where the repository will be maintained
mkdir /opt/svnrepos
cd /opt/svnrepos
svnadmin create projectName

Step 2: Add project to SVN
#Create project directory if it does not exist
mkdir /home/user/projectName
svn import /home/user/projectName file:///opt/svnrepos/projectName -m "Initial commit of project"

Step 3: Checkout project and start using SVN
cd /home/user/workspace
svn co file:///opt/svnrepos/projectName
cd projectName
svn status
svn log
