Always astonishing what a good bashism can do.

Up to now we only know about the astonishment of fxkl47BF@protonmail.com
that grep -c does not count characters.

For a more complicated use case i would write a little C program where
i'd be in control of every single bit of throughput.
(Ok, C causes scars on the programmer's self esteem. But what does not
kill me makes me just stronger. I'm a vim user.)


Have a nice day :)
