![]() In order to prevent any issues you would need to do some more advance checks on the user input in order to make sure the script will continue to work fine even if the provided input does not match our needs. While the script is working fine, it expects that the user will provide the requested input. Also whenever is possible use 2 factor authentication as this will provide additional layer of security for your account. :warning: As already mentioned, please make sure to use strong passwords in order to make sure your account is protected. This is pretty much how you can use simple bash script to generate random passwords. # This is where the magic happens! # Generate a list of 10 strings and cut it to the desired value provided from the user for i in \n" Conclusion Generate the passwords and then print it so the user can use it. Printf "\n" read -p "How many characters you would like the password to have? " pass_length In this case we would like to know how many characters the password needs to be: # Ask user for password length We can then continue and ask the user for some input. We use it to tell the operating system which interpreter to use to parse the rest of the file. The scriptįirst we begin the script with the shebang. With this command we take the output from /dev/urandom and translate it with tr while using all letters and digits and print the desired number of characters. Tr -cd '' < /dev/urandom | fold -w10 | head -n 1 ![]() We would also need to manipulate the output using tr in order to translate it. Since it is intended for most cryptographic purposes. The most preferred way is to use the pseudorandom number generator - /dev/urandom.Keep in mind that openssl might not be installed on your system so it's likely that you will need to install it first in order to use it. We can also use openssl in order to generate pseudo-random bytes and run the output through base64.We can hash the date using md5, sha or just run it through base64. However we also further manipulate the output in order to use it as randomly generated password. The date command will output the current date and time. I will cover few of them and will provide some examples. You can use several commands in order to generate a random string of characters.

When it comes to generating a random string of characters it's not different as well. One of the great benefits of Linux is that you can do a lot of things using different methods. I'm running the script locally on my Linux laptop but if you're using Windows PC you can ssh to any server of your choice and execute the script there. You can use any text editor like vi, vim, nano or Visual Studio Code. You would need a bash terminal and a text editor. The script will then generate 5 random passwords with the length that was specified in step 1. ![]()
