This was tested on macOS (instead of AIX), but it should work on AIX as well:
If you remove the # characters from the above script, it will show you the input it got from /dev/urandom and the possible passwords it tested from that input before reaching a password that meets your criteria.
Note that the dd in the pipeline is because standard implementations of awk are defined to work on text files while the output from the tr command is a single incomplete line of infinite length (while a text file is limited to lines containing no more than LINE_MAX bytes (where LINE_MAX is 2048 bytes on most UNIX systems)). Having dd produce lines of 61 characters per line (counting the terminating <newline> character) was a choice to make the debugging output easy to read in an 80 column window. If you don't care about the debugging output, you might want to increase the line size slightly. Note, however, that even with a line length of just 60 characters, I only saw this script read a second line of input once in 50 tests with debugging output enabled. Furthermore, if you are using an awk that can handle "unlimited" line lengths, the algorithm used in this script will not make any attempt to look for a password until a complete line has been read.
It works but occasionally i am also getting the below prompt..how do i get rid of this

Dear UNIX Friends,
I was wondering if there is a random RGB color generator or any function in any unix platforms.
Please share your ideas.

There was an upload recently on generating a pseudo-random file when /dev/random does NOT exist.
This does not need /dev/random, /dev/urandom or $RANDOM either...
(I assume $RANDOM relies on the /dev/random device in some way.)
This code uses hexdump just because I like hexdump for ease of... (2 Replies)
Here is my new password generation script. The attachment, swordfish.txt, is in dos format. Remember that you need to use dos2unix or flip or something to get it into unix format.
The script is self documenting. It has an extensive help system built-in. And you can run:

Hi,
I need a script that will generate a set of random strings in sequence, with the ability to predetermine the length, quantity, and alphabet of individual string, and to use the outputs of earlier strings in the sequence to define the parameters of later strings. For examples, I might want... (5 Replies)
I've got a file (numbers.txt) filled with numbers and I want to replace each one of those numbers with a new random number between 0 and 9. This is my script so far:

rand=$(($RANDOM % 9))
sed -i s//$rand/g numbers.txtThe problem that I have is that it replaces each number with just... (2 Replies)

I need a great Password Generator program. I looked at a few of them, but none of them seemed to be what I wanted. So I have decided to write my own. (That's the cool thing about being a programmer....I always get what I want in software :) )
Do you have any password generators that you... (13 Replies)
