Subversion (or svn) is a source code manager. It helps managing multiple versions of a software that is evolving.

Sommaire

General Principles

Subversion, like CVS, uses a unique, centralized repository, where are stored all versions of the files of a project. Subversion is different from CVS through its versionning numbers that are global, rather than per file. Subversion also permits to rename or move a file without loosing its history.

The subversion repository can be located within a local directory or on a remote server.

Similar Commands Between CVS and SVN

  • cvs checkout => svn checkout (co)
 Usage : svn checkout URL[@REV] ... [LOCAL_PATH]
 Useful option(s) :
      --revision (-r)
      --non-recursive (-N)
  • cvs add => svn add
 Usage : svn add PATH ...
 Useful option(s) :
      --non-recursive (-N)
  • cvs commit => svn commit (ci)
 Usage : svn commit [LOCAL_PATH ...]
 Useful option(s) :
      --message (-m) TEXT
      --non-recursive (-N)
  • cvs update => svn update (up)
 Usage : svn update [LOCAL_PATH ...]
 Useful option(s) :
      --non-recursive (-N)
  • cvs remove => svn delete (del, remove, rm)
 Usage : svn delete LOCAL_PATH... or URL ...
 Useful option(s) :
      --force
      --force-log
      --message (-m) TEXT

Note : in the case of a LOCAL_PATH, you will have to run svn commit in order to propagate the delete operation to the repository. In the case of a URL, the operation is directly applied to the repository.

Exclusive Commands to Subversion

  • svn blame (praise, annotate, ann)
 Description : For a given target, show the revision number, the author and the message of all modifications.
 Usage : svn blame TARGET[@REV] ...
 Useful option(s) :
       --revision (-r) REV
  • svn cat
 Description : Shows the content of files or URLs
 Format : 	svn cat CIBLE[@REV] ...
 Useful options :
       --revision (-r) REV
  • svn copy (cp)
 Description : Copy or branch from a file or directory. The new copy inherits the historic of the source.
 Usage : svn copy SRC DST
 SRC and DST are either a path to a local directory or file (LC) or a URL :
   LC  -> LC  : copy with historic (waiting for commit)
   LC  -> URL : immediate copy or branch creation to the repository
   URL -> LC  : local branch from the repository (waiting for commit)
   URL -> URL : immediate branch or tag creation on the server side
 Options utiles :
       --message (-m) TEXT
  • svn import
 Description : Imports a non-versioned file or directory into the repository.
 Usage : svn import [LOCAL_PATH] URL
 Useful option(s) :
      --message -(-m) TEXT

Note : if you want to import a complete directory, make sure the URL contains the name of the local directory. Subversion will NOT automatically append the local directory's name to the URL. For example:

 svn import ./project1 https://server/path/to/repos/project1
  • svn info
 Description : Show some information about local or remote targets
 Usage : svn info [TARGET[@REV] ...]
 Useful option(s) :
       --recursive (-R)
  • svn list
 Description : List the versioned content of a directory
 Usage : svn list [TARGET[@REV] ...]
 Useful option(s) :
       --revision (-r) REV
       --verbose (-v)
       --recursive (-R)
  • svn log
 Description : Show the log entries for a set of revisions or files.

 Useful option(s) :
       --revision (-r) REV

   commit the addition. In the repository, the addition is commited at the same time.
 Usage : svn mkdir PATH or URL
 Useful option(s) :
       --message (-m) TEXT
  • svn move (mv, rename, ren)
 Description : Moves or renames a target. In the working directory, you still have to commit the
   modification. In the repository, the commit is done immediately.
 Usage : svn move SRC DEST
 Useful option(s) :
       --message (-m) TEXT
  • svn status (stat, st)
 Description : Show the state of files and directories in a working copy of a versioned directory.
 Usage : svn status [LOCAL_PATH ...]
