You need to run a single command on a Linux workstation, but your account lacks the required permissions. Which command lets you execute just that one command with the privileges of another user (typically root) without launching a new shell session?
su
chmod
yum
sudo
Using sudo lets an authorized user run one command with the security privileges of another account. Unlike su, which starts a new shell, sudo elevates only the specified command. yum installs or updates software packages, and chmod merely changes file permissions-it does not run a command with different user privileges.
