unsort

UNSORT(1)						    BSD General Commands Manual 						 UNSORT(1)

NAME

     unsort -- reorder lines in a file in semirandom ways

SYNOPSIS

     unsort [-hvrpncmMsz0l] [--help] [--version] [--random] [--heuristic] [--identity] [--concatenate] [--merge] [--merge-random] [--seed integer]
	    [--zero-terminated] [--null] [--linefeed] [file ...]

DESCRIPTION

     unsort prints the lines in the input files (or standard input) in semi-random order.  Available algorithms are a Mersenne Twister based PRNG
     and a heuristic algorithm that aims to create a subjective even distribution.

   Command line options
     -h, --help
	     Display a concise summary of the available options and argument syntax.

     -v, --version
	     Display version and copyright information.

     -r, --random
	     Use the Mersenne Twister based randomization algorithm.

     -p, --heuristic
	     Use the heuristic "shuffling" algorithm which permutes the lines in such a way that they're spread more or less evenly in the output.
	     This is the default.

     -n, --identity
	     Do not reorder lines in the input. Useful if you just want to merge the files.

     -r, --concatenate
	     Concatenate all input files then apply the shuffling algorithm to the result as a whole.

     -m, --merge
	     Shuffle all input files seperately then merge the result.	Equal-sized files will be merged in the order in which they appear on the
	     command line.

     -M, --merge-random
	     Shuffle all input files seperately then merge the result.	Equal-sized files will be merged in random order.  This is the default.

     -s, --seed integer
	     Use this integer as a seed, instead of random data from the environment.

     -z, --zero-terminated, -0, --null
	     Lines are terminated with a  character.

     -l, --linefeed
	     Lines are terminated with a 
 character.	This is the default.
