This documentation was written to describe the 1.7.x series of Apache™ Subversion®. If you are running a different version of Subversion, you are strongly encouraged to visit http://www.svnbook.com/ and instead consult the version of this documentation appropriate for your version of Subversion.
Subversion attempts to erase a lot of the confusion between the cvs status and cvs update commands.
The cvs status command has two purposes:
first, to show the user any local modifications in the working
copy, and second, to show the user which files are out of date.
Unfortunately, because of CVS's hard-to-read status output, many
CVS users don't take advantage of this command at all. Instead,
they've developed a habit of running cvs
update or cvs -n update to quickly
see their changes. If users forget to use
the -n option, this has the side effect of
merging repository changes they may not be ready to deal
with.
Subversion removes this muddle by making the output of svn status easy to read for both humans and parsers. Also, svn update prints only information about files that are updated, not local modifications.
svn status prints all files that have local modifications. By default, the repository is not contacted. While this subcommand accepts a fair number of options, the following are the most commonly used ones:
-u
Contact the repository to determine, and then display, out-of-dateness information.
-v
Show all entries under version control.
-N
Run nonrecursively (do not descend into subdirectories).
The svn status command has two output formats. In the default “short” format, local modifications look like this:
$ svn status M foo.c M bar/baz.c
If you specify the --show-updates
(-u) option, a longer output format is
used:
$ svn status -u
M 1047 foo.c
* 1045 faces.html
* bloo.png
M 1050 bar/baz.c
Status against revision: 1066
In this case, two new columns appear. The second column
contains an asterisk if the file or directory is out of date.
The third column shows the working copy's revision number of the
item. In the previous example, the asterisk indicates that
faces.html would be patched if we updated,
and that bloo.png is a newly added file in
the repository. (The absence of any revision number next to
bloo.png means that it doesn't yet exist in
the working copy.)
For a more detailed discussion of svn status, including an explanation of the status codes shown in the previous example, see the section called “See an overview of your changes”.
svn update updates your working copy, and prints only information about files that it updates.
Subversion has combined CVS's P and
U codes into just U. When
a merge or conflict occurs, Subversion simply prints
G or C, rather than a
whole sentence about it.
