6.1.3. w¶

w: Like who, except also lists what command they are currently running. It’s the creepy version of who.

6.1.4. hostname¶

hostname: Print the name of the computer being used. It may be useful in a shell script in case certain resources are only available on some machines.

6.1.5. finger¶
