What is the usual location for system binaries in Linux?

The usual location for system binaries in Linux is typically found in the directory designated specifically for essential system utilities and administrative commands. The directory that holds these type of binaries is often referred to as "/sbin". This directory contains executables that are primarily intended to be used by the system administrator for system maintenance and recovery tasks, such as fsck and reboot. These commands are not usually intended for general user operations, which is why they’re placed in a separate location.

In contrast, the directory "/usr/bin" contains user commands that are more commonly accessible to all users, while "/etc" is primarily for configuration files specific to the system. The "/lib" directory contains shared libraries that are required by binaries to function rather than the binaries themselves. Each of these directories serves distinct purposes, with "/sbin" specifically geared towards system management tasks.
