Difference between /bin vs /sbin vs /usr/bin vs /usr/sbin vs /usr/local/bin vs /usr/local/sbin

/bin This directory contains executable programs which are needed in
single user mode and to bring the system up or repair it.

/sbin Like /bin, this directory holds commands needed to boot the sys-
tem, but which are usually not executed by normal users.

This is the primary directory for executable programs. Most
programs executed by normal users which are not needed for boot-
ing or for repairing the system and which are not installed
locally should be placed in this directory.

This directory contains program binaries for system administra-
tion which are not essential for the boot process, for mounting
/usr, or for system repair.

Binaries for programs local to the site (not part of the standard OS build)

Locally installed programs for system administration (not part of the standard OS build)
