OS X: pbcopy Rocks!
I'm still getting to know my new MacBook Pro. In a lot of ways, I'm stuck with rough approximations of the power I used to have on my Ubuntu Thinkpad; mostly this boils down to ignorance on my part and a persistent feeling of having to look a little too hard for answers. It's a lot like having someone come in and rearrange your kitchen while you're out. You come back, and it's a little harder to find the paring knife (I also run into this when either mine or Emily's parents visit, and wind up helping us unload the dishwasher...but that's a story for another day).
But I didn't start this entry to rant and rave about how left-handed my new macbook feels; I actually found something really cool tonight among the flotsam and jetsam of this wanna-be linux OS: pbcopy. This nifty utility lets you pipe the output from some random shell command to your clipboard, making is a piece of cake to then paste it into your current editor. This works especially well when you're working with Eclipse IDE, and use the "Java Stacktrace" console to help locate the sources of your errors. What I'm actually using it for tonight is to generate patch files. I modify the codebase using Eclipse or a variety of other methods, then call:
svn diff | pbcopy
Now, I'm ready to Cmd-Tab to my favorite editor, Cmd-N to get a new buffer, and Cmd-V to create my new patch file.
