Svnlook Switches
Switches in svnlook are global, just like in svn and svnadmin; however, most switches only apply to one subcommand since the functionality of svnlook is (intentionally) limited in scope.
--no-diff-deletedPrevents svnlook 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.
--revision (-r)Specify a particular revision number that you wish to examine.
--revpropOperates on a revision property instead of a Subversion property specific to a file or directory. This switch requires that you also pass a revision with the --revision (-r) switch. See «Unversioned Properties» for more details on unversioned properties.
--transaction (-t)Specify a particular transaction ID that you wish to examine.
--show-idsShow the filesystem node revision IDs for each path in the filesystem tree.
