Linux is a multi-user operating system. We have the ability to switch between users easily and it be useful to know who you are and what processes you're running and when you last logged in.
- [Instructor] It's nice to have an idea who you are,…and on the command line we have tools for this.…When we first login,…our prompt changes to affect our username.…To see this, let's open a Terminal…by going into Applications, Favorites, Terminal.…I'm going to make my terminal full screen…and bump my font size.…Looking at my prompt,…it has my username, at, the host name of this computer,…space, tilde,…and then the last character is a dollar sign.…The tilde signifies the directory I'm currently in.…My current directory isn't named tilde,…but rather the tilde is a shortcut to my home directory,…which we'll cover later in this course.…
The last character is a dollar sign,…showing that I'm a normal user.…If the last character were a hash symbol…it would mean that I'm a super user.…Another way of telling who we are…is to use a who am I command.…Type in whoami and hit enter.…Whoami very simply prints out which user I'm logged in as.…We have another command called log name…which at first glance looks identical.…Type in logname and hit enter.…
