An exhaustive SVN cheat sheet found here<\/a> :<\/p>\n

* Create a repository
\n– use the database backend
\nsvnadmin create ~\/svn_repos\/Eccos
\n– use the filesystem backend
\nsvnadmin create –fs-type=fsfs PATH<\/p>\n

* Import a revision
\nsvn import -m “Initial import” Eccos file:\/\/\/home\/reichr\/svn_repos\/Eccos\/trunk<\/p>\n

* Check out a revision
\nsvn co file:\/\/\/home\/reichr\/svn_repos\/Eccos\/trunk Eccos<\/p>\n

* Dump a repository
\nsvnadmin dump \/home\/reichr\/svn_repos\/Eccos | gzip -9 > dump.gz
\nsvnadmin dump \/home\/reichr\/svn_repos\/Eccos | gzip -9 > `date “+Eccosdump%Y-%m-%d_%H:%M:%S.gz”`<\/p>\n

* Load contents of a dump into a repository
\ngunzip -c dump.gz | svnadmin load \/home\/reichr\/svn_repos\/e<\/p>\n

* Import from an existing directory, no need to check it out again
\nIt should work, but you could also check it out right into \/etc. Something
\nlike this:<\/p>\n

$ svnadmin create \/var\/svnrepos\/admin
\n$ svn mkdir -m “initial setup” file:\/\/\/var\/svnrepos\/admin\/trunk
\nc:> svn mkdir -m “initial setup” file:\/\/\/c:\/fhs\/svn_repos\/trunk
\n$ cd \/etc
\n$ svn co file:\/\/\/var\/svnrepos\/admin\/trunk .
\n$ svn add passwd group
\n$ svn commit -m “start loading it in”<\/p>\n

I tested the ‘svn co’ into ‘.’ just now. Works great.<\/p>\n

* svn propset
\nsvn propset svn:keywords “LastChangedDate LastChangedRevision Id Author” weather.txt
\nsvn propset svn:keywords “LastChangedDate LastChangedRevision Id” slides.tex<\/p>\n

* Before an update you could use the following to get the log messages of the changes:
\nsvn log -rBASE:HEAD<\/p>\n

* Upgrade to a new subversion version
\n$ mv repos repos.tmp
\n$ svnadmin create repos
\n$ svnadmin-old dump repos.tmp | svnadmin load repos
\n$ # copy over any hook scripts and stuff from repos.tmp to repos<\/p>\n

* Upgrade my repositories at work
\n$ mv Eccos Eccos-old
\n$ svnadmin create Eccos
\n$ gunzip -c dumps\/Eccosdump2003-11-11_10:08:54.gz | svnadmin load Eccos<\/p>\n

* Checkout from a repository over ssh
\nsvn co svn+ssh:\/\/felix\/home\/reichr\/svn_repos\/XSteveData\/trunk data<\/p>\n

* Change the path of the repository for a working copy
\nsvn switch –relocate file:\/\/\/original\/path\/to\/repos file:\/\/\/new\/path<\/p>\n

* Put system configuration in a subversion repository
\n– create the repository \/home\/reichr\/svn_repos\/WaldiConfig
\nsvnadmin create WaldiConfig
\n– Import an empty directory
\ncd to an empty directory
\nsvn import -m “Initial import” . file:\/\/\/home\/reichr\/svn_repos\/WaldiConfig\/trunk
\n– Check it out from Waldi (user reichr)
\nsvn co svn+ssh:\/\/felix\/home\/reichr\/svn_repos\/WaldiConfig\/trunk WaldiConfig
\n– Put files in the repository (as root)
\nmv \/etc\/fstab \/home\/reichr\/WaldiConfig\/etc
\nln -s \/home\/reichr\/WaldiConfig\/etc\/fstab \/etc\/fstab<\/p>\n

* Network a repository via svn+ssh:
\n– create the repository on the repository host:
\nsvnadmin create rp1 — this is located at \/home\/svtest\/rp1
\n– Import data to the repository:
\nsvn import -m”Initial import” svn+ssh:\/\/svtest@host\/rp1\/trunk
\n– Checkout the project:
\nsvn co svn+ssh:\/\/svtest@host\/home\/svtest\/rp1\/trunk p1<\/p>\n

* Warning:
\nPutting the repository on a network filesystem my be a bad idea,
\nbecause the repository may get corrupted!
\nIt is better to put it on a local filesystem.<\/p>\n

* Merge from a branch back to the trunk
\nSvnMerging<\/p>\n

* Generate a patch to undo some local changes and redo them later
\n> What usually happens to me is that I’ve changed N files in M different
\n> directories distributed all over the filesystem, and I want to check in
\n> N-1 of them.<\/p>\n

Yeah, I have to do this all the time. But I can eye a potentially
\ncomplex command-line pretty well, so if I need to commit all but one
\nfile, I do this:<\/p>\n

% svn diff path\/to\/file_not_committing > \/tmp\/patch.txt
\n% svn revert path\/to\/file_not_committing
\n% svn ci -m “committing all the stuff i wanted to”
\n% patch -p0 < \/tmp\/patch.txt\n\nRevert is your friend. Learn it, use it, looooooooooove it.\n\n* Revert to a previous version\nsvn co project\n
\nsvn ci foo.c (commits to r348)
\n
\nsvn merge -r348:347 foo.c
\nsvn ci foo.c (commits 349)<\/p>\n

note the ordering of the revision numbers in the merge command. what this
\nreally says is “make a diff between revision 348 and 347, and apply it
\nimmediately to foo.c”<\/p>\n

if you are trying to revert a directory tree with moves or deletes in it, and
\nare getting arcane errors, try the –ignore-ancestry flag.<\/p>\n

* Edit the commit\/log messages after the commit
\nRead chapter 7, regarding unversioned properties attached to revisions.
\nYou want to change the svn:log property:
\n$ svn propedit -r N –revprop svn:log URL<\/p>\n

* Svn repository via apache2
\n– manage the htpasswd file:
\nhttp:\/\/search.cpan.org\/dist\/Apache-Htpasswd\/Htpasswd.pm
\n– a sample cgi script to alter users passwords via Apache::Htpasswd:
\nhttp:\/\/perlmonks.thepen.com\/178482.html
\n– A full featured utility to add\/change users via commandline or cgi:
\nhttp:\/\/stein.cshl.org\/~lstein\/user_manage\/<\/p>\n

* Use svn:mime-type for nicer www browsing of a repository
\n> When browsing your repository, if you click on a filename, you see the
\n> contents of the file (assuming it’s a text file) formatted as if with a
\n> 

 tag.  So, if the file happens to be an HTML file, you essentially see
\n> the source HTML code.  Which, in most cases, is perfectly correct.
\n>
\n> However, there are times when it would be nice to see the _formatted_ HTML
\n> instead.  Is there a way to do this, other than the cumbersome Save Page As
\n> \/ Open File process within the browser?<\/p>\n
If you set the svn:mime-type property on that file to ‘text\/html’ and
\ncommit, your browser should see subsequent revisions of that file as
\nformatted HTML.<\/p>\n
* Versionize symlinks, unix permissions and ownership
\nsvnpropset.pl, svnpropget.pl from Steve Wray 
\n(search on the svn mailing list or in my mail-boxes)<\/p>\n
* track svn trunks\/branches with all history in arch
\n– svn-arch-mirror
