With no FILE, or when FILE is -, read standard input. SYNOPSIS shuf [-e|--echo] [-i|--input-range] [-n|--head-count] [-o|--output] [--random-source] [-r|--repeat] [-z|--zero-terminated] [-h|--help] [-V|--version] [file-or-args] DESCRIPTION Shuffle the input by outputting a random permutation of input lines. Each output permutation is equally likely. With no FILE, or when FILE is -, read standard input. OPTIONS -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 -h, --help Print help -V, --version Print version [file-or-args] VERSION v0.0.26 shuf 0.0.26 shuf(1)
