When working on Linux, you might not always be able to see which user you are logged in as by default, or perhaps you want confirmation before making a change.
Thankfully, find out is very simple and is done using a one word command which will instantly output the username as a result.
LINUX-HOST# whoami admin
Thankfully, this also works in Windows too, so its helpful to know regardless of which OS you are working on.
A short post, but it helps me remember and hopefully it can benefit someone – I hope its helpful!
