The command "pwgen -c ${length}" generates a random password using the "pwgen" command-line utility.
Here's the breakdown of the command:
-
"pwgen": It is a command-line utility used to generate random passwords. It is commonly used in Unix-like operating systems.
-
"-c": It is an option or flag provided to the "pwgen" command. In this case, it specifies that the generated password should include at least one capital letter. By including this flag, the generated password will have a mix of lowercase and uppercase letters.
-
"${length}": It is a variable used to represent the desired length of the generated password. The value of the variable will determine how many characters the password should have. "${length}" is a placeholder, and you need to replace it with an actual number when using the command.
For example, if you want to generate a random password with a length of 10 characters and containing at least one capital letter, you would execute the command "pwgen -c 10".
