hanchang / print-all-crontabs
Created August 24, 2011 04:49
Script to print out all crontabs on a machine. Must be run as root.
#!/bin/bash
# Courtesy of:
# http://stackoverflow.com/questions/134906/how-do-i-list-all-cron-jobs-for-all-users
# System-wide crontab file and cron job directory. Change these for your system.
CRONTAB='/etc/crontab'
CRONDIR='/etc/cron.d'
# Single tab character. Annoyingly necessary.

Passwordless SSH/SFTP access to a server

Passwordless SSH/SFTP for dummies

To get SSH or SFTP access to a server without using a password you need to have a SSH key pair for each computer you want to be able to access the server from. In this document I’ll describe the steps you need to take to generate a key pair if you don’t have one already. If you do, you can use your public key(s) to get access to the server.

I'll also explain how to connect to your server using Cyberduck. Click here to skip to that part.

Disclaimer and stuff

This guide is written with newbies in mind, so I'm very thorough in describing the steps that you must take. This guide will not cover setting up the server side of this system. It assumes that there's a server running with SSH enabled.

Designing a GraphQL API

Tutorial: Designing a GraphQL API

This tutorial was created by Shopify for internal purposes. We've created a public version of it since we think it's useful to anyone creating a GraphQL API.

It's based on lessons learned from creating and evolving production schemas at Shopify over almost 3 years. The tutorial has evolved and will continue to change in the future so nothing is set in stone.
