Let me know

lmk is a simple command line tool written in Go that draws your attention to a terminal when another command finishes running.


Yeah, it may sound silly but how often do you run a command that you know that takes a lot of time to complete, you go do something else and forget that the command was running? Even worse, what about when you get side tracked for a bit longer than you should and when you Alt+Tab to check if the command has finished it actually errored along the way?

Those situations happen to me more than you might think. Throughout the day I might run many bundle installs, vagrant ups, rake specs, etc.. that takes more than a few seconds to complete. Because looking at a black screen with a blinking cursor and a whole lot of output is pretty boring, during that period I usually Alt+Tab to check my emails or twitter and many times I get side tracked before realizing that I should have been doing something else.

How does it work?

Let's say you want to run the specs for that legacy project you have just been assigned and the full run takes 5 minutes to complete. With lmk you can run lmk rake spec and as soon as rake spec finishes running you'll see a notify-send notification poping up on your desktop.

But that's not enough, what if you miss the notification while you are away from the keyboard? Well, in that case lmk will keep letting you know that the command finished every 30 seconds until you go back to the terminal session that you left the command running and hit Enter.
