This is a complete list of all environment variables that affect CVS.
updatewill try hard to make the files in your working directory read-only. When this is not set, the default behavior is to permit modification of your working files.
$CVSROOTis not set, or if you wish to override it for one invocation, you can supply it on the command line: `cvs -d cvsroot cvs_command...' Once you have checked out a working directory, CVS stores the appropriate root (in the file `CVS/Root'), so normally you only need to worry about this when initially checking out a working directory.
$CVSEDITORdoes not exist in CVS 1.3, but the next release will probably include it.
$RCSBINis not set, and no path is compiled into CVS, it will use
$PATHto try to find all programs it uses.
$HOMEPATHis used for Windows-NT). see section Default options and the ~/.cvsrc file
:ext:access method is specified. see section Connecting with rsh.
cvs. see section Connecting with rsh
cvs login server. Default value is `$HOME/.cvspass'. see section Using the client with password authentication
cvs login server. see section Using the client with password authentication
$CVS_CLIENT_LOG.in' and everything send from the server is logged into `
TMPDIR. See section Global options, for a description of how to specify this. Some parts of CVS will always use `/tmp' (via the
tmpnamfunction provided by the system). On Windows NT,
TMPis used (via the
_tempnamfunction provided by the system). The
patchprogram which is used by the CVS client uses
TMPDIR, and if it is not set, uses `/tmp' (at least with GNU patch 2.1).
CVS invokes RCS to perform certain operations. The following environment variables affect RCS. Note that if you are using the client/server CVS, these variables need to be set on the server side (which may or not may be possible depending on how you are connecting). There is probably not any need to set any of them, however.
$RCSINIToptions are prepended to the argument lists of most RCS commands.
