while [ "$n" -le 7]

Any ideas how I can generate a random password that doesn't require bash installed, and that takes into account all the special characters?

I did the following on all the previously listed versions and could not find bash:
lslpp -l | grep bash*

But I suppose another option would be to deploy bash on all those machines, and then the script would work fine Smilie

As for Perl, none of the admins here use it, and I for one don't know the first thing about it :/

That said I avoid special characters because they can play dirty tricks depending how you connect.. But it doesnt seem to affect you since it works under LINUX... (typically when using X software emulation from PCs... )
