SVN commit command

To add a file/folder to the project, a good way is:

First of all add your files to /path/to/your/project/my/added/files, and then run following commands:

svn cleanup /path/to/your/project

svn add --force /path/to/your/project/*

svn cleanup /path/to/your/project

svn commit /path/to/your/project -m 'Adding a file'

I used cleanup to prevent any segmentation fault (core dumped), and now the SVN project is updated.

Command-line SVN

You need to add your files to your working copy, before you commit your changes to the repository:

svn add <file|folder>

Afterwards:

svn commit

See here for detailed information about svn add.

TortoiseSVN

It works with TortoiseSVN, because it adds the file to your working copy automatically (commit dialog):

If you want to include an unversioned file, just check that file to add it to the commit.
