You can run `tty` to see your current TTY
This is not a super useful fact but I thought it was cool and didn’t know it
before: you can run tty to get the TTY device for your current terminal
session.
For example, if I run tty and get /dev/pts/0, I can then go to a
different terminal tab, run echo blah > /dev/pts/0, and than blah will show
up in the original terminal tab.
