This command is used to change the expiry date of a user account in Linux. Let's break down the components:
-
sudo
: It is a command that allows you to execute a command with administrative privileges. It stands for "Super User Do." -
chage
: It is a utility in Linux used to modify the password expiry information for a user. It primarily handles password aging, but with the--expiredate
option, it also changes the account's expiry date. -
--expiredate ${YYYY-MM-DD}
: This option allows you to set a specific date (in the format of year-month-day) as the new expiry date for the user account. -
${username}
: It is the placeholder for the username you want to modify. Replace it with the actual username without the braces.
By combining these parts, the command will change the expiry date of the user account specified by ${username}
to the date given in the ${YYYY-MM-DD}
format.
