DR_PERMUTATE

NAME

dr_permutate - print randomly permutated arguments or stdin

EXAMPLE

Running

$ dr_permutate foo bar baz

could return

bar foo baz

. Running

$ cat <<EOF | dr_permutate
foo
bar
baz

could return

bar
foo
baz

.

HISTORY

This script was initially written on 2001-05-06.

BUGS

When called without any arguments, stdin is read in core entirely.

The GNU coreutils utility shuf(1) implements the same functionality in a better way, you’re probably better off using that.
