Everything you wanted to know about the shell but were afraid to ask

A new way to interact

This event will be presented in a new format that brings the audience into the action. The first 50 people to join get optional camera and mic access for the opportunity to ask questions and interact directly with your trainer and peers. You can turn your camera off at any time, and you can always interact through chat. Before joining the course, please take a moment to read the O'Reilly learning platform code of conduct.

Course outcomes:

  • Understand how to use internal field separators
  • Learn how globs and regular expressions differ
  • Understand how to use terminal codes in different contexts
  • Learn how to interpret background task management output
  • Understand how command auto-completion works

Course description:

Join expert Ian Miell to deepen your understanding of a core command-line technology through discussion of specific issues that confuse many engineers, such as why terminals only sometimes show the output of commands even when redirected, why the shell uses globs and regular expressions and why they differ, and how command completion works. Find answers directly related to challenges you face when writing shell scripts or operating on the command line and leave with increased confidence in your ability to write and review shell scripts.
