I have this nice password generator which I use on my work, mostly linux based:
< /dev/urandom tr -dc "[:graph:]" | head -c 12; echo Of course this isn't portable so I rewrote it to: < /dev/arandom tr -dc "[:graph:]" | iconv -c -t ASCII | dd count=1 bs=12 2> /dev/null; echo Now you may look at it and wonder what's the 'iconv -c -t ASCII |' is doing in there. If you remove it you'll notice weird characters slipping through. Is that right? Why does that happen? If I look at the tr code it should only allow ascii chars without whitespace from my limited understanding of C. # Han
