fish

Fish Shell

• Finally, a command line shell for the 91
• Design Philosophy
• The variables setting works quite differently from bash, see set - display and change shell variables

Commands/Caveats

The philosophy of Fish is eliminating bespoke syntax and use explicit commands, so…

• Use math for math expansion
• Use seq <n> for brace expansion with range.
• Keybindings
  • Many emacs keybindings
  • Alt - l to list files in current dir.

Plugins

• Oh My Fish
  • An all-in-one framework that comes with plugin manager, themes, and prompts, similar to Oh My Zsh.
  • Not so actively maintained.
  • Has its own config directory ~/.config/omf.
• Fisher

  • Ctrl+Alt+F - files and dirs (can Enter to cd into)

  • Ctrl+Alt-P - processes
