Tiny Password Generator

Found on Korben’s Blog, a nice way to generate a random password on UNIX:

# < /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c8
tOULPeOk

Just create an alias for a more convenient day-to-day use:

# alias gen_pw='< /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c8'
# gen_pw
wbk0ewpn

Note: this works only with the GNU version of head. Solaris or BSD versions have no '-c' flag!
