in reply to Random string generator

Thanks to jmcnamara, we have this example:

perl -le 'print map{(a..z)[rand 26]} 0..rand 10'

which I have extended thusly:

perl -le 'print map{(a..z,A..Z,0..9)[rand 62]} 0..7'

and which you could extend as needed.

    For use in a function which is much easier to remember.
    print randStr(8)."\n"; sub randStr { return join('', map{('a'..'z','A'..'Z',0..9)[rand 62]} 0..shift); }
