shuf option descriptions are different from GNU, which could cause some confusion #193
Description
Help output differences...
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
