In command line platforms online, like for instance the one on Codecademy, when I run
for cmd in w who whoami id do echo $cmd $cmd echo ========================= echo " " done
w 00:52:54 up 8 days, 14:10, 0 users, load average: 3.78, 2.98, 2.69 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT ========================= who ========================= whoami ccuser ========================= id uid=1000(ccuser) gid=1000(ccuser) groups=1000(ccuser) =========================
Note that only
id output something. When I run the same thing on my computer, I see similar results for all commands.
Why doesn't Codecademy display the user for
who? What's different about these commands?
