how to get random printable characters

The linux comand is this:

cat /dev/urandom | base64  [ENTER]

See for example this web page:

To get a “photo” like in my previous post, I grab a screenshot of the window that is displaying the pseudo-random base64 characters.

It can be good source material to generate possible passwords.  For example, fill a 6×6 empty table with randomly selected characters read from the screenshot.  Then, select 8, 10, 12 or 16 out of 36 as the password.  Destroy the 6×6 table. Place the password somewhere safe, or alternatively memorize it.
