This is why I love programming with Unix tools available. Let’s say you need to grep your code (text files, remember), and it’s taking longer than, say, 1 second. Perhaps you have a bunch of generated files or something that are hogging all of your disk space. How do you find out? A simple one-liner:
du --exclude=.git | sort -n
I love *nix.
du is the tool that reports on file size, and since I use git, I pass it –exclude git so that it doesn’t consider that directory (I already have grep aliased to ignore .git). Then I pipe that into sort, using -n so that it sorts the sizes numerically, instead of alphanumerically. The result is that it shows me the big, pointless files it’s grepping through.
And now my search is back to a happy 1 second.
