Remove .svn files recursively

to svn recursive remove by GeckoPie on Jun 30, 2008

find . -type d -name '.svn' -exec rm -rf {} \;

recursevly remove .svn files from an existing repo

to svn recursive remove git by shan on Jun 29, 2008

If you need to take a project out of scm, you can run this bash script from the top folder - and it will remove all .svn folders recursevly (sp)

Works well for
- changing an svn checkout into and svn export
- switching from svn to git

find . -type d -name '.svn' -exec rm -rf {} \;

Remove Existing MySQL Installations

to mysql osx installer remove symlink uninstall by minofare on Jan 03, 2008

If you already have MySQL installed and used the package installer from MySQL to install it, you need to remove a single file (actually a symlink) to disable it:

sudo rm /usr/local/mysql

If you also installed the StartupItem package, you’ll want to remove it as well. Keep in mind that if you ever want to auto-start the old version of MySQL later on, you’ll need to re-download the package installer and reinstall the StartupItem.

sudo rm -rf /Library/StartupItems/MySQLCOM/
