Tip of the Week

Using shell history to be quick and efficient:

• The ‘arrow-up’ key inserts your previous command
• Use ctrl-r keyboard shortcut to search through your history
• Zsh has a builtin r (alias for fc -e -) command:

    % kubectl --context dev-gke get pods -n namespace
    % r dev=prod
    kubectl --context prod-gke get pods -n namespace
  

• The history command, which is really just fc, has numerous flags:
  • fc alone open your editor of choice to edit the last command
  • fc -l prints your recent history
  • fc <num> opens your editor with the command with that history ID
  • fc <num> <num> edits commands in that range
  • fc -s <num> runs the command without editing
• The ever-popular !! for executing the previous command without editing
  • !!:s/foo/bar executes the last command, replacing the first ‘foo’ with ‘bar’ (like r)
  • !!:gs/foo/bar is the same as above, except replacing all instances of ‘foo’
  • !!:$ inserts the last argument from the previous command into your new command (aliased to !$)

      % mkdir /tmp/baz
      % cd !$
      cd /tmp/baz
