I need to have whole string up to 'new line' - (LF, 10#10, 16#A)

SHUFFLE(1) BSD General Commands Manual SHUFFLE(1)NAME
shuffle -- print a random permutation of the command line arguments
SYNOPSIS
shuffle [-0] [-f filename ...] [-n number] [-p number] [arg] [...]
DESCRIPTION
The shuffle program prints a random permutation (or ``shuffle'') of its command line arguments. This can be useful in shell scripts for
selecting a random order in which to do a set of tasks, view a set of files, etc.
If the -f option is given, the data is taken from that files' contents or if the filename is - ``stdin''.
If the -n option is given, its argument is treated as a number, and the program prints a random permutation of the numbers greater than or
equal to 0 and less than the argument.
If the -p option is given, its argument is treated as a number, and the program prints that number of randomly selected lines or arguments in
a random order.
The -0 option changes the field separator character from
to , so that the output is suitable to be sent to xargs(1) (to handle filenames
with whitespace in them).
EXAMPLES
$ shuffle a b c d
c
b
d
a
$ shuffle -p 1 a b c d
d
$ shuffle -n 4 -p 2
0
3
SEE ALSO jot(1), random(6)HISTORY
The shuffle program first appeared in NetBSD 1.4.
