Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

What about just using pwgen?

pwgen 8 1
Comment by DNSpyder 217 weeks and 3 days ago

And the bonus with pwgen is that the passwords are usually pronouncable, so they are easier to remember than pure noise. Also for the truly paranoid, pwgen displays many candidate passwords at once, so anyone looking over your shoulder can't tell which one you've chosen.

I've created a better script that doesn't require nonstandard programs such as uuencode. Throw this in your .bashrc or execute the function after defining and you're set.

randompassword(){

local c=$(tput setaf 6)

local r=$(tput sgr0)

#local chars='A-Z-a-z-0-9'

local chars="'A-Z-a-z-0-9~+,?:@$%^&*'"

if [[ "$1" == "" ]] ; then

echo -n "${c}"

< /dev/urandom tr -dc "$chars" | head -c16

echo -n "${r}"

else

echo -n "${c}"

< /dev/urandom tr -dc "$chars" | head -c$1

echo -n "${r}"

fi

echo -e " "

}

Sorry, that code is:

randompassword(){

local c=$(tput setaf 6)

local r=$(tput sgr0)

#local chars='A-Z-a-z-0-9'

local chars="'A-Z-a-z-0-9~+,?:@$%^&*'"

if [[ "$1" == "" ]] ; then

echo -n "${c}"

< /dev/urandom tr -dc "$chars" | head -c16

echo -n "${r}"

else

echo -n "${c}"

< /dev/urandom tr -dc "$chars" | head -c$1

echo -n "${r}"

fi

echo -e " "

}
