Linux Tutorial Series – 88 – Review

Here is the video version, if you prefer it:

We looked at history and variables. In particular, we looked at:

  • history is used to look at history; use CTRL + R for reverse search in history and CTRL + J to copy the command to your clipboard
  • Dot files (files whose filenames begin with a dot) are hidden by default
  • Variables are named parts of computer memory where values are stored
  • Environment variables are variables passed to the shell by the operating system
  • Shell variables are local to the shell
  • Command path stores all of the places to look for executables
  • Interactive shells require user input, non-interactive don’t
  • Login shells exist to do some things only once
  • Your Terminal application is an interactive, non-login shell
  • Place almost all changes you want permanently in .bashrc file in your home directory

Let’s carry on with our Linux journey!
