watch

i wrote a small script on python that calls a command line from the console in order to hibernate a linux machine (or shut itself down in case one word is changed) and then wake up after some time. The command is called again again and again through the watch command. import os import time os.system("watch -n 20 sudo rtcwake -u -s 10 -m mem") So the rtcwake command is called again 20 seconds after the pc has wokn up again. I would like another script to be run every time the computer wakes up. I already have this other script, it is a countdown. I want to do this in order to show the user how

Is there a way for Node.js to listen to a change in a particular data in a collection of MongoDB, and fire an event if a change happens? I believe you are looking for a database trigger . Unfortunately, MongoDB has no support for them yet, so I don't think you can listen for changes directly from the database. You'll need to setup some sort of notification system (e.g. pub/sub) that alerts interested parties when a collection has changed. Well, this is an old question, but I was struggling with the same thing. I found a number of tidbits that helped me put together a solution, and I've

Grunt takes a quite long to compile the css file, I am not sure if this is normal but regular compass watch takes around 5 seconds. So the question is if there is any way to speed up the compilation time with Grunt or is it better to just stick with compass watch?

It seems the local server started with "heroku local web" does not watch for file changes and restart itself. How can I make it do this? The easiest way to do this is to run nodemon with heroku local as the executable - i.e. nodemon --exec "heroku local" . However, heroku local exits with a non-zero exit code for the default nodemon shutdown signal (SIGUSR2), so you need to add an additional flag to nodemon to set the interrupt signal to SIGTERM. nodemon --exec "heroku local" --signal SIGTERM (tested with heroku-cli@6.14.31-33a2d0a, nodemon@1.12.1, node@8.5.0) heroku local just uses node

I'm new to grunt, still learning, so I came up to a very strange problem. When I run "watch" task, my command line becomes blocked, so basically I cant do anything on it. Bare in mind that the task is completed with success. This is my command line output: C:\server\css-test>grunt w Running "watch" task Waiting...OK >> File "compass-examples-master\02\sass\screen.scss" changed.
