in reply to Random string generator

Thanks to jmcnamara, we have this example:

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

[download]

which I have extended thusly:

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

[download]

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);
}
