SHUF(1) General Commands Manual SHUF(1)
NAME
shuf โ randomly permute input lines
SYNOPSIS
shuf [-hv] [-n count] [-o outfile] [-rz] [file]
shuf [-hv] -e [-n count] [-o outfile] [-rz] [args ...]
shuf [-hv] -i lo-hi [-n count] [-o outfile] [-rz]
DESCRIPTION
shuf is a utility that outputs a random permutation of its input lines.
By default, shuf reads from stdin and outputs to stdout.
The options are as follows:
-e Use a space-separated list of command-line args as input.
Cannot be combined with -i.
-h Print usage information and exit.
-i lo-hi
Use the range of positive integers from lo to hi as input.
Cannot be combined with -e.
-n count
Print at most count lines.
-o outfile
Write output to outfile instead of stdout.
-r Do not permute. Instead, choose lines at random, with
replacement. When used without -n, shuf repeats indefinitely.
-v Print version information and exit.
-z Delineate lines with the NUL character instead of the newline
character.
EXIT STATUS
The shuf utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
Flip a coin ten times:
shuf -e -n 10 -r Heads Tails
Select five numbers from 10 to 20:
shuf -i 10-20 -n 5
Set a random desktop background image from the user's collection:
ls ~/wallpaper | shuf -n 1 | feh --bg-fill
