a fast way to repeat output a byte

the speed is about 500MB/s on my machine.

i think it's fast enough to output not too many bytes.

while a C program may output 1GB per sencond on my machine.

if the size is not the power of 512,you may change the bs and count in dd.

Just a simple way without the need of additional tools. Of course, replace eth0 with your IF.

This generates a unique and secure password with SALT for every website that you login to

This is a safest variation for "sitepass function" that includes a SALT over a long loop for sha512sum hash

create random string from /dev/urandom (or another length)

The same command, but with a base64 filter, more forgiving for special characters than tr.
