simple command line password generator
To use type
pwgen
and you will get a random 12 symbol password
if you type
pwgen {n}
you get a password of {n} characters length.
if you type
pwgen {n} {m}
you get {m} passwords of {n} characters length
pwgen does not use zero or 'o' or '1' and 'L' to avoid difficult visual representation in certain fonts. Also Y and Z are not used to allow the password to be typed the same way on a US keyboard as well as on a German keyboard (who has Y and Z swapped).
