Pretty print SQL query with python in one line

You need to apt-get install python-sqlparse. This command simply formats a sql query and prints it out. It is very useful when you want to move a sql query from commandline to a shell script. Everything is done locally, so you don't need to worry about copying sql query to external websites. Show Sample Output

easily find megabyte eating files or directories

This is easy to type if you are looking for a few (hundred) "missing" megabytes (and don't mind the occasional K slipping in)... A variation without false positives and also finding gigabytes (but - depending on your keyboard setup - more painful to type): $du -hs *|grep -P '^(\d|,)+(M|G)'|sort -n (NOTE: you might want to replace the ',' according to your locale!) Don't forget that you can modify the globbing as needed! (e.g. '.[^\.]* *' to include hidden files and directories (w/ bash)) in its core similar to: http://www.commandlinefu.com/commands/view/706/show-sorted-list-of-files-with-sizes-more-than-1mb-in-the-current-dir
