Subversion Propset Script

I use a script to set the svn:keywords properties recursively for all files of a given pattern:

Modify the PATTERNS and KEYWORDS variables as you like, and execute it with

to set properties for all the files found by the script. You can do a

to list all files that are modified with this action, and commit via

Secure SSH, CVS, SCP without Password Prompt

For the old version of this homepage I have used CVS to update the websites. I have done this via SSH, which is pretty secure but has the annoying disadvantage of asking for a password for each operation. If you can trust the security of your client computer, there is a way to get rid of the password altogehter, without loosing security:

  1. Suppose the domain name of your server is server, and your login name loginname.
  2. On the client, generate a public and private key.

    When asked for a password, simply press return. The private key is stored in ~/.ssh/id_dsa, and the public key in ~/.ssh/ Never give the private key away!

  3. Copy the public file to the server with
  4. Login on the server with

    append the copied file to ~/.ssh/authorized_keys with

  5. If you want to enable this features on other servers, just repeat step 3 on each of the servers.

That’s it! If you have done everything correctly, the next time you login via SSH or use CVS over SSH, you will not need to enter a password yet you have a secure connenction.


Subversion has the ability to output a log file in XML format. I think it would be pretty straightforward to implement an application in Ruby (mabe with use of Amrita), that creates some nice looking statistic about the repository.

On a side note, I have a personal subversion repository that contains everything I have accomplished during my study of Software Engineering in Hagenberg. This dates back to somewhere in 2000, and so far I am at revision 3628, and the repository uses about 500MB. It is a bit strange that 5 years worth of work can fit on a single CD 8-)
