htpasswd:tldr:31839

The command "htpasswd -b ${filename} ${username} ${password}" is used to create or update an Apache HTTP server password file with a specified username and password combination.

Here's a breakdown of the command:

• "htpasswd": It is the command used for managing the password file.
• "-b": It is an option that specifies that the password should be specified in a command-line argument rather than prompted interactively.
• "${filename}": This placeholder represents the name and path of the password file that you want to create or update. You need to replace it with the actual filename and path.
• "${username}": This placeholder represents the username that you want to add or update. Replace it with the desired username.
• "${password}": This placeholder represents the password for the specified username. Replace it with the desired password.

So, when running this command, you would replace "${filename}" with the actual name and path of the password file, "${username}" with the desired username, and "${password}" with the desired password. The command will then create or update the specified password file with the provided username and password.
