概要

svn update [PATH...]

描述

svn update brings changes from the repository into your working copy. If no revision is given, it brings your working copy up-to-date with the HEAD revision. Otherwise, it synchronizes the working copy to the revision given by the --revision option. As part of the synchronization, svn update also removes any stale locks (see “有时你只需要清理”一节) found in the working copy.

For each updated item, it prints a line that starts with a character reporting the action taken. These characters have the following meaning:

第一列的字符反映文件本身的更新，而第二列会反映文件属性的更新。

获取你上次更新之后版本库的修改：

$ svn update
A  newdir/toggle.c
A  newdir/disclose.c
A  newdir/launch.c
D  newdir/README
Updated to revision 32.

You can also “update” your working copy to an older revision (Subversion doesn't have the concept of “sticky” files like CVS does; see 附录 B, CVS 用户的 Subversion 指南):

$ svn update -r30
A  newdir/README
D  newdir/toggle.c
D  newdir/disclose.c
D  newdir/launch.c
U  foo.c
Updated to revision 30.
