DR_PERMUTATE(1) Draai 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
.

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.
