Control-T to Show “cp” Status

Dave Dribin:

Mind blown: Hit Ctrl-T while performing a long running cp command. Shows current input and output file and the percentage complete.

The Control-T sends a SIGINFO signal. It also works with dd and ping.

The same works for a long running "dd" command.

I've learned that when installing an image for Raspberry Pi on a flashdisk via "dd" -- Ctrl+T would summon a current status on the console. Now I know same is valid for "cp" too.
