* * * Using SVN commands, you can retrieve past versions based on time or revision number, or view the specific changes made in a particular version. The following four commands can be used to view SVN history: * **svn log:** Used to display information such as the author, date, and paths of SVN versions. * **svn diff:** Used to show line-level details of specific modifications. * **svn cat:** Retrieves and displays the content of a file from a specific version on the current screen. * **svn list:** Displays the files in a directory or those present in a specific version. * * * ## 1、svn log It can display all information. If you only want to view information between two specific versions, you can use: root@tutorial:~/svn/tutorial01/trunk# svn log -r 6:8------------------------------------------------------------------------ r6 | user02 | 2016-11-07 02:01:26 +0800 (Mon, 07 Nov 2016) | 1 line change HelloWorld.html first.------------------------------------------------------------------------ r7 | user01 | 2016-11-07 02:23:26 +0800 (Mon, 07 Nov 2016) | 1 line change HelloWorld.html second ------------------------------------------------------------------------ r8 | user01 | 2016-11-07 02:53:13 +0800 (Mon, 07 Nov 2016) | 1 line SVN readme.------------------------------------------------------------------------ If you only want to view the version modification information for a specific file, you can use **svn log** followed by the file path. root@tutorial:~/svn/tutorial01# svn log trunk/HelloWorld.html ------------------------------------------------------------------------ r7 | user01 | 2016-11-07 02:23:26 +0800 (Mon, 07 Nov 2016) | 1 line change HelloWorld.html second ------------------------------------------------------------------------ r6 | user02 | 2016-11-07 02:01:26 +0800 (Mon, 07 Nov 2016) | 1 line change HelloWorld.html first.------------------------------------------------------------------------ r5 | user01 | 2016-11-07 01:50:03 +0800 (Mon, 07 Nov 2016) | 1 line ------------------------------------------------------------------------ r4 | user01 | 2016-11-07 01:45:43 +0800 (Mon, 07 Nov 2016) | 1 line Add function to accept input and to display array contents ------------------------------------------------------------------------ r3 | user01 | 2016-11-07 01:42:35 +0800 (Mon, 07 Nov 2016) | 1 line ------------------------------------------------------------------------ r2 | user01 | 2016-08-23 17:29:02 +0800 (Tue, 23 Aug 2016) | 1 line first file ------------------------------------------------------------------------ If you want to get directory information, you need to add **-v**. If you want to display directory information limited to N records, use **svn log -l N -v**. root@tutorial:~/svn/tutorial01/trunk# svn log -l 5 -v ------------------------------------------------------------------------ r6 | user02 | 2016-11-07 02:01:26 +0800 (Mon, 07 Nov 2016) | 1 line Changed paths: M /trunk/HelloWorld.html change HelloWorld.html first.------------------------------------------------------------------------ r5 | user01 | 2016-11-07 01:50:03 +0800 (Mon, 07 Nov 2016) | 1 line Changed paths: M /trunk/HelloWorld.html ------------------------------------------------------------------------ r4 | user01 | 2016-11-07 01:45:43 +0800 (Mon, 07 Nov 2016) | 1 line Changed paths: M /trunk/HelloWorld.html Add function to accept input and to display array contents ------------------------------------------------------------------------ r3 | user01 | 2016-11-07 01:42:35 +0800 (Mon, 07 Nov 2016) | 1 line Changed paths: A /trunk/HelloWorld.html (from /trunk/helloworld.html:2) D /trunk/helloworld.html ------------------------------------------------------------------------ r2 | user01 | 2016-08-23 17:29:02 +0800 (Tue, 23 Aug 2016) | 1 line Changed paths: A /trunk/helloworld.html first file ------------------------------------------------------------------------ * * * ## 2、svn diff Used to check the details of historical modifications. * Check local modifications * Compare working copy with repository * Compare repository with repository **（1）、If you use svn diff without any parameters, it will compare your working file with the "original" copy cached in .svn.** root@tutorial:~/svn/tutorial01/trunk# svn diffIndex: rules.txt ===================================================================--- rules.txt (revision 3)+++ rules.txt (working copy)@@ -1,4 +1,5 @@Be kind to others Freedom = ResponsibilityEverything in moderation -Chew with your mouth open **（2）、Compare working copy with repository** Compare your working copy with version 3 of the file rule.txt in the repository. svn diff -r 3 rule.txt **（3）、Compare repository with repository** Pass two version numbers separated by a colon via -r(revision), and these two versions will be compared. Compare the changes in this file between revision 2 and 3 in the SVN working version. svn diff -r 2:3 rule.txt * * * ## 3、svn cat If you only want to check a past version without viewing their differences, you can use svn cat svn cat -r Version number rule.txt This command will display the content of that file under that version number. * * * ## 4、svn list **svn list** allows you to view files in a directory without downloading them to the local directory: $ svn list README branches/ clients/ tags/
