18.4. Path For System Administration Utilities

Certain utilities used for system administration (and other privileged commands) may be stored in /sbin, /usr/sbin, and /usr/local/sbin. Applications requiring to use commands identified as system administration utilities should add these directories to their PATH. By default, as described in POSIX 1003.1-2008 (ISO/IEC 9945-2009), standard utilities shall be found on the PATH returned by getconf PATH (or command -p getconf PATH to be guaranteed to invoke the correct version of getconf).
