Using Subversion: A Quick Tour

This section provides a very quick tour of using Subversion for version control. We start with the initial version of a project for importing into Subversion:

    $ find /tmp/hello -print                  
               Show directory layout
    /tmp/hello
    /tmp/hello/branches                       Directory for branch development
    /tmp/hello/tags                           Directory for tagged releases
    /tmp/hello/trunk
    /tmp/hello/trunk/hello.c                  Mainline development is done on the trunk
    /tmp/hello/trunk/Makefile
    /tmp/hello/trunk/README

The next steps are to create the repository and then to import the project into it:

    $ svnadmin create /path/to/svnrepos
    $ svn import /tmp/hello file:///path/to/svnrepos -m "initial import"
    Adding         /tmp/hello/trunk
    Adding         /tmp/hello/trunk/hello.c
    Adding         /tmp/hello/trunk/Makefile
    Adding         /tmp/hello/trunk/README
    Adding         /tmp/hello/branches
    Adding         /tmp/hello/tags

    Committed revision 1.

Now that the project exists in Subversion, we check out a working copy into a sandbox underneath our home directory and start making changes:

    $ cd                                           
               Move to home directory
    $ svn checkout file:///path/to/svnrepos hello  
               Check out working copy
    A  hello/trunk
    A  hello/trunk/hello.c
    A  hello/trunk/README
    A  hello/trunk/Makefile
    A  hello/branches
    A  hello/tags
    Checked out revision 1.

    $ cd hello/trunk                               
               Change to sandbox
    $ vi message.c hello.c Makefile                
               Make changes
    3 files to edit

    $ cat message.c                                
               Show newly created file
    const char message[  ] = "hello, world!";
    $ make                                         
               Compile program and test it cc -c -o hello.o hello.c cc -c -o message.o message.c cc -O ...
