1.3. Concurrent Versions System (CVS)

In Red Hat Enterprise Linux 6, CVS is provided by the cvs package. To install the cvs package and all its dependencies on your system, type the following at a shell prompt as root:

yum install cvs

yum install cvs

This installs a command line CVS client, a CVS server, and other related tools to the system.

When using CVS on the command line, certain commands such as cvs import or cvs commit require the user to write a short log message. To determine which text editor to start, the cvs client application first reads the contents of the environment variable $CVSEDITOR, then reads the more general environment variable $EDITOR, and if none of these is set, it starts vi.

To persistently change the value of the $CVSEDITOR environment variable, run the following command:

echo "export CVSEDITOR=command" >> ~/.bashrc

echo "export CVSEDITOR=commandCVSEDITOR=command" >> ~/.bashrc

This adds the export CVSEDITOR=command line to your ~/.bashrc file. Replace command with a command that runs the editor of your choice (for example, emacs). Note that for this change to take effect in the current shell session, you must execute the commands in ~/.bashrc by typing the following at a shell prompt:

. ~/.bashrc

. ~/.bashrc

echo "export CVSEDITOR=emacs" >> ~/.bashrc
. ~/.bashrc

~]$ echo "export CVSEDITOR=emacs" >> ~/.bashrc
~]$ . ~/.bashrc
