apg: Create a password with maximum length of 16.
$ apg -x ${16}
try on your machine
The command "apg -x ${16}" is using the "apg" program with the flag "-x" followed by a variable "${16}".
The "apg" program is a password generator utility that generates random, strong passwords. The "-x" flag tells the program to include at least one character from each of four character classes - uppercase letters, lowercase letters, digits, and non-alphanumeric characters.
The variable "${16}" is a placeholder that represents the 16th argument passed to the command. In shell scripting, the variables starting with "$" and enclosed in curly braces "{}" are used to reference command-line arguments. So, in this case, the value specified as the 16th argument will be used as a parameter for the password generation.
