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 \0 character.

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