DR_PERMUTATE(1)

NAME
dr_permutate - print randomly permutated arguments or stdin

SYNOPSIS
dr_permutate arguments dr_permutate

DESCRIPTION
When called with arguments, dr_permutate returns its arguments in randomly permutated order, space separated. When called without any arguments, dr_permuate expects a line-oriented file on stdin. It returns the contents of this file, with lines randomly permutated.

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.
