Question 88

Which commands can you use to change a user's account aging information? (Choose THREE correct answers.)

A.usermod
B.passwd
C.chattr
D.chage
E.chsh

Correct Answer: A,B,D

The commands that can be used to change a user's account aging information are:
* usermod: this command can modify various user account properties, including the password expiration date, the account expiration date, the minimum and maximum password age, the password warning period, and the password inactivity period. To use this command, you need to specify the option and the value for the property you want to change, followed by the username. For example, to set the password expiration date for the user test to February 11, 2022, you can run:
usermod -e 2022-02-11 test
To view the current account aging information for a user, you can use the -l option with the usermod command. For example, to view the information for the user test, you can run:
usermod -l test
* passwd: this command can change the password of a user account, as well as some password aging options. To use this command, you need to specify the username and the option for the property you want to change. For example, to change the password of the user test, you can run:
passwd test
To set the maximum password age for the user test to 90 days, you can run:
passwd -x 90 test
To view the current password aging information for a user, you can use the -S option with the passwd command. For example, to view the information for the user test, you can run:
passwd -S test
* chage: this command can change the user password expiry and aging information, such as the password expiration date, the account expiration date, the minimum and maximum password age, the password warning period, and the password inactivity period. To use this command, you need to specify the option and the value for the property you want to change, followed by the username. For example, to set the account expiration date for the user test to February 11, 2022, you can run:
chage -E 2022-02-11 test
To view the current account aging information for a user, you can use the -l option with the chage command.
For example, to view the information for the user test, you can run:
chage -l test
The other options are incorrect because:
* chattr: this command can change the file attributes on a Linux file system, such as making a file immutable, append-only, or undeletable. It has nothing to do with user account aging information.
* chsh: this command can change the login shell of a user account, such as bash, zsh, or ksh. It has nothing to do with user account aging information.
