Notes on bash

This is just a random collection of commands which I have found useful in Bash. This Gist is expected to grow over time (until I have mastered the whole of Bash). Another useful resource is this list of Unix commands on Wikipedia. Hyperlinked bash commands in general lead to relevant Man (manual) pages.

Contents

• Notes on bash
  • Contents
  • Get the current date and time and generate timestamped filenames with date
• Display date and time in bash history using HISTTIMEFORMAT
