Ive created a bunch of nifty small bash scripts to do quick and dirty tasks for me when im in shell world. You can grap a copy of it right here and put them on your server or whatever.
importdb/exportdb = imports or exports a sql file to a database
deletesvn = removes all .svn folders from your current directory recursive
createrepo/deleterepo = creates and deletes a repository and setup a project structure with trunk, branch, and tags
I was looking for a way to switch between my line out options on my Mac Pro. I wanted to be able to switch between my headphones and my table speakers. So i stumbled across this little app that adds an icon to my menu bar with a bunch of switching options. You can pick it up at http://www.rogueamoeba.com/freebies/ The company makes awesome apps like Airfoil and Nicecast. Also the pong screensaver is great!
