One of the most annoying things you need to handle sometimes is password change. Of course, you need to pick a good one, not just “blue123”.
Sure, there are many websites that can generate a random number or string for you such as random.org, but did you know you can do it very simply from command line?
You just need to use the tr command to reach from /dev/urandom .. so it is pretty random:
tr -dc _A-Z-a-z-0-9 < /dev/urandom | head -c10
If you need to change the password length, you just need to change the -c parameter. Also, you can change the characters to be included pretty easily with the -d parameter.
