shuf − generate random permutations
shuf -e [OPTION]... [ARG]...
shuf -i LO-HI [OPTION]...
Write a random permutation of the input lines to standard output.
arguments to long options are mandatory for short options
treat each ARG as an input line
treat each number LO through HI as an input line
output at most COUNT lines
write result to FILE instead of standard output
get random bytes from FILE
end lines with 0 byte, not newline
display this help and exit
output version information and exit
With no FILE, or when FILE is −, read standard input.
