Always astonishing what a good bashism can do. > But at this point, we have to wonder what the *actual* goal is. Up to now we only know about the astonishment of fxkl4...@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 :) Thomas
