Current shuf:

shuf (V coreutils) 0.0.1
-----------------------------------------------
Usage: shuf [options] [ARGS]

Description: Shuffles its input by outputting a random permutation of its input lines

Options:
  -e, --echo                Treat each command-line operand as an input line
  -i, --input-range <string>
                            Act as if input came from a file containing the range of unsigned decimal integers lo…hi, one per line
  -n, --head-count <int>    Output at most count lines. By default, all input lines are output
  -o, --output <string>     Write output to output-file instead of standard output
  --random-source <string>  Use file as a source of random data used to determine which permutation to generate
  -r, --repeat              Repeat output values
  -z, --zero-terminated     Delimit items with a zero byte rather than a newline
  -h, --help                display this help and exit
  --version                 output version information and exit

GNU shuf:

Usage: shuf [OPTION]... [FILE]
  or:  shuf -e [OPTION]... [ARG]...
  or:  shuf -i LO-HI [OPTION]...
Write a random permutation of the input lines to standard output.

With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.
  -e, --echo                treat each ARG as an input line
  -i, --input-range=LO-HI   treat each number LO through HI as an input line
  -n, --head-count=COUNT    output at most COUNT lines
  -o, --output=FILE         write result to FILE instead of standard output
      --random-source=FILE  get random bytes from FILE
  -r, --repeat              output lines can be repeated
  -z, --zero-terminated     line delimiter is NUL, not newline
      --help        display this help and exit
      --version     output version information and exit
