Bash keyboard shortcuts

  • ctrl + a - go to beginning of line
  • ctrl + e - go to end of line
  • ctrl + l - similar to running clear command
  • ctrl + k - clear entire line upto the cursor
  • ctrl + w - delete the last word

Node

You can get data from a Node.js script using the p flag. Furthermore, you don't need to require a core node module.

e.g. node -p 'querystring.parse(process.argv[1])' time=1900 returns [Object: null prototype] { time: '1900' }
