Generate a random string of characters: To create a secure password, we need to generate a random string of characters. Bash provides the /dev/urandom device file, which generates random data. We can use the tr command to filter out unwanted characters and limit the length of the generated string.
Customize the password length and character set: You can customize the length of the generated password by modifying the length variable in the script. Additionally, you can change the character set by modifying the tr command. For example, to include special characters, you can modify it to tr -dc ‘[:graph:]’.
Make the script executable: Save the script in a file, for example, password_generator.sh. Make the script executable using the chmod command:
Step 4: Run the password generator: Execute the script by running ./password_generator.sh in the terminal. The script will generate and display a secure password.
In this article, we learned how to create a password generator using Bash scripting. By generating random strings of characters, we can create secure passwords for various purposes.
