From shuf(1):

DESCRIPTION
       Write a random permutation of the input lines to standard output.

       With no FILE, or when FILE is -, read standard input.

       Mandatory arguments to long options are mandatory for short options
       too.

       -e, --echo
              treat each ARG as an input line

       -i, --input-range=LO-HI
              treat each number LO through HI as an input line

       -n, --head-count=COUNT
              output at most COUNT lines

       -o, --output=FILE
              write result to FILE instead of standard output

       --random-source=FILE
              get random bytes from FILE

       -r, --repeat
              output lines can be repeated

       -z, --zero-terminated
              line delimiter is NUL, not newline

       --help display this help and exit

       --version
              output version information and exit

I think this should work like rpn(1) and take standard input if there are no arguments, so no need for -e. No need of course for --version and --help. I don’t think -r or -n belong here. I’m not sure about having analogues --random-source and -i.

And -o is redundant with redirection.

And `-o` is redundant with redirection.

Maybe shuffle?

Then you could do stuff like for f in /media/audio/*; do scrut -f "$f" && out "$f"; done | shuffle | xargs mpv.

I agree with -e being unnecessary and file arguments not being taken (just mm -i f -i f2 | shuffle), no -i (use sed) or -n (use sed) or -o (| mm -o). -z seems useful to me but with -0, though its use here makes me think ASV would be a better fit. I'm gonna talk about --random-source in #8.

-r seems useful to me but necessitates -n to make sure it doesn't repeat forever. Maybe we should have a repeat(1) command to take standard input and spit it out repeated n times.

I'm gonna talk about `--random-source` in #8. `-r` seems useful to me but necessitates `-n` to make sure it doesn't repeat forever. Maybe we should have a repeat(1) command to take standard input and spit it out repeated *n* times.
