What I have are two text files that I need to shuffle randomly, but I need the two files to be randomly shuffled the same way. I have heard of shuf but I do not know how to use it for two files. Maybe there is also an easy/simple awk command I do not know about that could handle this problem.
for example:
before shuffling
Code:
file 1:
one
two
three
four
five
file 2:
1
2
3
4
5
and after shuffling
Code:
file 1:
five
one
four
three
two
file 2:
5
1
4
3
2
As you can see the lines still match up across the two files (ofcourse this is just an example, I need the output to be random).

Hi,
From some time, we have noticed that our ascii files have started corrupting due to the presence of some random control characters (^@, ^M, ^H, ^D). The characters appear randomly on any file after the process that creates the file finishes. If we rerun the process, the files re creates... (0 Replies)
I have a directory of files that look like filename 001.ext, filename 002.ext, etc. I'd like to rename the files with unique random numbered names, so that the original filenames are stripped and the files are given a new, random number name. I'm not super new to UNIX, but I don't often use it for... (2 Replies)

Hi,
Is there any way I can shuffle the numbers randomly. I have been trying to google and I found lots of 'generator' but is it possible to find the background logic to create randomness?
Thanks, (3 Replies)

shuffle
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.
