Why Bash?


  • It is literally everywhere! Available on virtually every Linux/macOS system and easily added to Windows
  • Powerful: Pipes, redirection, and process substitution
  • Simple: Easy to start, deep to master
  • If you are gonna use Linux, you WILL use bash at some point and more and more

.bashrc


My simple explaination of what a .bashrc is:


> Your pre-flight checklist procedures your terminal completes every time it starts


My Bash Workflow


I use bash for:


  • Development scripts: Build, test, deploy automation
  • System administration: User management, backups, monitoring
  • Data processing: Log analysis, file transformations
  • Dotfiles management: Symlinking, bootstrapping new machines

Tips and Tricks


  • Pipe | everything you can to another program
  • Use grep andawk`` every single time you are viewing more than 1 line of text
  • Use type command to determine if something is installed on your system (instead of which)
  • Use [[]] instead of [ ] for conditionals
  • Quote your variables: "$var"
