A.5 Common command options

This section describes the `command_options' that are available across several CVS commands. These options are always given to the right of `cvs_command'. Not all commands support all of these options; each option is only supported for commands where it makes sense. However, when a command has one of these options you can almost always count on the same behavior of the option as in other commands. (Other command options, which are listed with the individual commands, may have different behavior from one CVS command to the other).

The `history' command is an exception; it supports many options that conflict even with these standard options.

-D date_spec

Use the most recent revision no later than date_spec. date_spec is a single argument, a date description specifying a date in the past.

The specification is sticky when you use it to make a private copy of a source file; that is, when you get a working file using `-D', CVS records the date you specified, so that further updates in the same directory will use the same date (for more information on sticky tags/dates, see section Sticky tags).

`-D' is available with the annotate, checkout, diff, export, history, ls, rdiff, rls, rtag, tag, and update commands. (The history command uses this option in a slightly different way; see section history options).

For a complete description of the date formats accepted by CVS, Date input formats.

Remember to quote the argument to the `-D' flag so that your shell doesn't interpret spaces as argument separators. A command using the `-D' flag can look like this:

 
$ cvs diff -D "1 hour ago" cvs.texinfo
-f

When you specify a particular date or tag to CVS commands, they normally ignore files that do not contain the tag (or did not exist prior to the date) that you specified. Use the `-f' option if you want files retrieved even when there is no match for the tag or date. (The most recent revision of the file will be used).

Note that even with `-f', a tag that you specify must exist (that is, in some file, not necessary in every file). This is so that CVS will continue to give an error if you mistype a tag name.

`-f' is available with these commands: annotate, checkout, export, rdiff, rtag, and update.

WARNING: The commit and remove commands also have a `-f' option, but it has a different behavior for those commands. See commit options, and Removing files.

-k kflag

Override the default processing of RCS keywords other than `-kb'. See section Keyword substitution, for the meaning of kflag. Used with the checkout and update commands, your kflag specification is sticky; that is, when you use this option with a checkout or update command, CVS associates your selected kflag with any files it operates on, and continues to use that kflag with future commands on the same files until you specify otherwise.

The `-k' option is available with the add, checkout, diff, export, import, rdiff, and update commands.

WARNING: Prior to CVS version 1.12.2, the `-k' flag overrode the `-kb' indication for a binary file. This could sometimes corrupt binary files. See section Merging and keywords, for more.

-l

Local; run only in current working directory, rather than recursing through subdirectories.

Available with the following commands: annotate, checkout, commit, diff, edit, editors, export, log, rdiff, remove, rtag, status, tag, unedit, update, watch, and watchers.

-m message

Use message as log information, instead of invoking an editor.

Available with the following commands: add, commit and import.

-n

Do not run any tag program. (A program can be specified to run in the modules database (see section The modules file); this option bypasses it).

This is not the same as the `cvs -n' program option, which you can specify to the left of a cvs command!

Available with the checkout, export, and rtag commands.

-P

Prune empty directories. See Removing directories.

-p

Pipe the files retrieved from the repository to standard output, rather than writing them in the current directory. Available with the checkout and update commands.

-R

Process directories recursively. This is the default for all CVS commands, with the exception of ls & rls.

Available with the following commands: annotate, checkout, commit, diff, edit, editors, export, ls, rdiff, remove, rls, rtag, status, tag, unedit, update, watch, and watchers.

-r tag
-r tag[:date]

Use the revision specified by the tag argument (and the date argument for the commands which accept it) instead of the default head revision. As well as arbitrary tags defined with the tag or rtag command, two special tags are always available: `HEAD' refers to the most recent version available in the repository, and `BASE' refers to the revision you last checked out into the current working directory.

The tag specification is sticky when you use this with checkout or update to make your own copy of a file: CVS remembers the tag and continues to use it on future update commands, until you specify otherwise (for more information on sticky tags/dates, see section Sticky tags).

The tag can be either a symbolic or numeric tag, as described in Tags-Symbolic revisions, or the name of a branch, as described in Branching and merging. When tag is the name of a branch, some commands accept the optional date argument to specify the revision as of the given date on the branch. When a command expects a specific revision, the name of a branch is interpreted as the most recent revision on that branch.

Specifying the `-q' global option along with the `-r' command option is often useful, to suppress the warning messages when the RCS file does not contain the specified tag.

This is not the same as the overall `cvs -r' option, which you can specify to the left of a CVS command!

`-r tag' is available with the commit and history commands.

`-r tag[:date]' is available with the annotate, checkout, diff, export, rdiff, rtag, and update commands.

-W

Specify file names that should be filtered. You can use this option repeatedly. The spec can be a file name pattern of the same type that you can specify in the `.cvswrappers' file. Available with the following commands: import, and update.
