Quickzi: Generate Random Passwords on the Linux Command Line

Are you new here? Subscribe to my RSS feed. Thanks for visiting!

Here is a quick one line command to generate a random password from the Linux command line.

# < /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c6

If you want a password length longer than 6, changing the -c6 to read -c8 will give you 8 random characters instead of 6.

Needs something to add a newline to the end.

Newline at the end:

$ echo `< /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c6`
