Account maintainance commands

Within commands below, Don't take square brackets, angle brackets and triple-dots literally:

  • < This > should be replaced with your own info - including the angle brackets
  • [This] is optional parts of the command - including the square brackets
  • ... means "repeat ad libitum" - leave it out or add more stuff similar to that right before the dots

Normal users

Create new account

  1. Pick a username:
  • Start with the initials of the user
  • Include also second letter of either first name or surname
  • If necessary, add third letter of first name or surname (or a trailing number)
  • The result should be practical (short and related to the name of the user) but must not be a nickname or initals: A username is comparable to the shape of a key - the user may get confused in every day use if it looks like a toy or jewelery!

    localadduser <username> <fullname> <cellphone> [<otherphone>] <addresshint> [<addresshint>...]
  • Full name: Full name (Capital and small letters allowed, as is space and special characters, but no comma!)
  • Cellphone: Cellphone number including country code but without other spaces. Like this: +45 40843136

Extend password lifespan
