Security-conscious users may remove the temporary administrator privileges upon completing the tasks requiring them by using the sudo -k command when from each tty or pts in which sudo was used (in the case of pts's, closing the terminal emulator is not sufficient). The equivalent command for kdesu is kdesu -s.
After authentication, and if the configuration file permits the user access, the system invokes the requested command. sudo retains the user's invocation rights through a grace period (typically 5 minutes) per pseudo terminal, allowing the user to execute several successive commands as the requested user without having to provide a password again.
An instance with elevated privileges must be launched in order to get "sudo" to give administrator privileges, and allow such access. [ 8 ] WSL 1 is not capable of running all Linux software, such as 32-bit binaries, [ 42 ] [ 43 ] or those that require specific Linux kernel services not implemented in WSL.

The Unix and Linux access rights flags setuid and setgid (short for set user identity and set group identity) [1] allow users to run an executable with the file system permissions of the executable's owner or group respectively and to change behaviour in directories. They are often used to allow users on a computer system to run programs with ...
A privilege is applied for by either an executed program issuing a request for advanced privileges, or by running some program to apply for the additional privileges. An example of a user applying for additional privileges is provided by the sudo command to run a command as superuser user, or by the Kerberos authentication system.
Prints a command to the terminal as Bash reads it. Bash reads constructs all at once, such as compound commands which include if-fi and case-esac blocks. If a set -v is included within a compound command, then "verbose" will be enabled the next time Bash reads code as input, ie, after the end of the currently executing construct. [108]
