generate passwords

Hi,
I wanted to share you something I've founded usefull:
Even we have to create safetly passwords for differents types of accounts or sessions..., and linux terminal can do it for you !
I made a mini-script that you can call in the terminal like that:

~/bin/creapwd.sh 32

make for you a password with 32 characters. Of course you can change the value you want.
That's it
creapwd.sh:

#!/bin/bash

# script to create pwd
##cat /dev/urandom|tr -dc _A-Z-a-z-0-9 |head -c60
# ex.: pwd with 32 characters: ~/bin/creapwd.sh 32

numcara=$1

tr -d -c "a-zA-Z0-9" < /dev/urandom | head -c "$numcara"

exit

Re: generate passwords

Great, works for me, thanks!

There is only one minor issue with the passwords created: It only has letters and numbers, but no special characters like !"§$%&=)(/ etc. - so it'd be easier for someone to make a brute-force attack (although over 20 characters are basically ok even without signs).

       -y, --symbols
              Include at least one special character in the password.

Re: generate passwords

@porkpiehat Sorry, I was referring to the bash script in the OP, but it looked like I was talking about pwgen. Thank you for that link @earlybird, that looks like a very useful utility.
