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
and after shuffling
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.

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)

array_rand
ARRAY_RAND(3) 1 ARRAY_RAND(3)array_rand - Pick one or more random entries out of an arraySYNOPSIS
mixed array_rand (array $array, [int $num = 1])
DESCRIPTION
Picks one or more random entries out of an array, and returns the key (or keys) of the random entries.
PARAMETERS
o $array
- The input array.
o $num
- Specifies how many entries should be picked.
RETURN VALUES
When picking only one entry, array_rand(3) returns the key for a random entry. Otherwise, an array of keys for the random entries is
returned. This is done so that random keys can be picked from the array as well as random values. Trying to pick more elements than there
are in the array will result in an E_WARNING level error, and NULL will be returned.
