"who am i" command returns empty prompt

I am following a book on Linux. One of the first commands is to execute who am i. It should return my username. However, it returns an empty prompt.

What am I missing?

I am using Fedora 25.

Solution

  • When you write:

    who am i

    You're actually passing two parameters ("am" and "i") to the who command:

    :~$ who --help
Usage: who [OPTION]... [ FILE | ARG1 ARG2 ]

    You want to do (without the spaces; it's a different function):

    whoami

    to get what you want.
