Some administrative commands are contained in regular user directories (such as /bin and
/usr/bin). This is especially true of commands that have some options available to everyone. An

To find commands intended primarily for the system administrator, check out the section 8 manual
pages (usually in /usr/share/man/man8). They contain descriptions and options for most
Linux administrative commands.
Some third-party applications add administrative commands to directories that are not in your
PATH. For example, an application may put commands in /usr/local/bin, /opt/bin, or
/usr/local/sbin. Some Linux distributions automatically add those directories to your PATH,
usually before your standard bin and sbin directories. In that way, commands installed to those
directories are not only accessible, but can also override commands of the same name in other
directories.
