Opps! Sorry ArcAngel, I had not noticed your report before. Better late than never I guess. Smilie

There is no X4, it only goes up to X3. The fix was to remove "!X4 && " from that line. Actually, it's odd that the script ran everywhere else.

I have recently been ordered to use 12 character randomly generated passwords that meet strong complexity requirements. That is why I have dusted off this old script. I need it badly right now. Ironically, I want to to run on Solaris just like ArcAngel. I also tested it on RedHat and it broke on the latest ksh. I had to change my character slicing technique to get it work. I used to do stuff like this:

Code:

first=${x%${x#?}}

to get the first character. That breaks depening on the contents of the field. That had always been the case but it breaks more easily with today's ksh. I switched to

Code:

        first=$x
        while ((${#first} > 1 )) ; do
               first=${first%?}
        done

which works all the time and it much faster than it looks. I upgraded the help system a little, corrected spelling errors, etc. I had to reverse engineer my own code so I upgraded the comments quite a bit as well. It saved me from needed to memorize a string of garbage from a lesser password generator. I hope others can use it as well.
