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
