commit
Create or update a working directory containing copies of the
source files specified by modules. You must execute
checkout before using most of the other CVS
commands, since most of them operate on your working
directory.
The modules are either
symbolic names for some
collection of source directories and files, or paths to
directories or files in the repository. The symbolic
names are defined in the `modules' file.
See modules.
Depending on the modules you specify, checkout may
recursively create directories and populate them with
the appropriate source files. You can then edit these
source files at any time (regardless of whether other
software developers are editing their own copies of the
sources); update them to include new changes applied by
others to the source repository; or commit your work as
a permanent change to the source repository.
Note that checkout is used to create
directories. The top-level directory created is always
added to the directory where checkout is
invoked, and usually has the same name as the specified
module. In the case of a module alias, the created
sub-directory may have a different name, but you can be
sure that it will be a sub-directory, and that
checkout will show the relative path leading to
each file as it is extracted into your private work
area (unless you specify the `-Q' global option).
The files created by checkout are created
read-write, unless the `-r' option to CVS
(see Global options) is specified, the
CVSREAD environment variable is specified
(see Environment variables), or a watch is in
effect for that file (see Watches).
Note that running checkout on a directory that was already
built by a prior checkout is also permitted.
This is similar to specifying the `-d' option
to the update command in the sense that new
directories that have been created in the repository
will appear in your work area.
However, checkout takes a module name whereas
update takes a directory name. Also
to use checkout this way it must be run from the
top level directory (where you originally ran
checkout from), so before you run
checkout to update an existing directory, don't
forget to change your directory to the top level
directory.
For the output produced by the checkout command
see update output.
