svnlook is a command-line utility for examining different aspects of a Subversion repository. It does not make any changes to the repository—it's just used for “peeking.” svnlook is typically used by the repository hooks, but a repository administrator might find it useful for diagnostic purposes.
Since svnlook works via direct repository access (and thus can be used only on the machine that holds the repository), it refers to the repository with a path, not a URL.
如果没有指定修订版本或事物，svnlook缺省的是版本库最年轻的(最新的)修订版本。
Options in svnlook are global, just as they are in svn and svnadmin; however, most options apply to only one subcommand since the functionality of svnlook is (intentionally) limited in scope:
--copy-info
导致 svnlook changed 复制源显示详细信息。
--no-diff-deleted
Prevents svnlook diff from printing differences for deleted files. The default behavior when a file is deleted in a transaction/revision is to print the same differences that you would see if you had left the file but removed all the content.
--no-diff-added
Prevents svnlook diff from printing differences for added files. The default behavior when you add a file is to print the same differences that you would see if you had added the entire contents of an existing (empty) file.
--revision (-r)
指定你希望检查的版本号。
--revprop
Operates on a revision property instead of a property specific to a file or
directory. This option requires that you also pass a revision with the
--revision (-r) option.
--transaction (-t)
指定你希望检查的事务 ID。
--show-ids
Shows the filesystem node revision IDs for each path in the filesystem tree.
