easily find megabyte eating files or directories

sorts the files by integer megabytes, which should be enough to (interactively) find the space wasters. Now you can dush for the above output, dush -n 3 for only the 3 biggest files and so on. It's always a good idea to have this line in your .profile or .bashrc Show Sample Output
