Tech Esoterica – CLI

These are general command-line interface shortcuts, useful for most things. ⊞ for Windows, □ for Linux/Mac (⌘ if Mac is different).

Parameters/Commands

Most of the commands have special elements that modify the command’s scope:

  • e.g., “ls -S -s” will list all the files in a directory, but also sort them by size and print their size as well.
    • ⊞: [COMMAND] /w /s /p
    • □: [COMMAND] -w -s -p
  • e.g., “dir /p” will print all the files in a directory, one page at a time.

To find all the parameters/options, consult the documentation:

  • help [command]
  • -h
  • –help
  • man
