HP Certified: HP-UX System Administration

8.11 The /usr Directory

This is an important directory, as most of the HP-UX system files are placed here. This directory contains a number of subdirectories that arrange different types of files. Figure 8-6 shows a partial structure of this directory. The most important file types are user - related commands, libraries, documentation and manual pages, contributed software, and X-Window system files.

/usr/bin

This directory contains user commands, applications, and utilities.

/usr/ contrib

Contains contributed software from other sources.

/usr/include

Header and include files used for programming.

/usr/lib

Libraries for programming and machine-dependent database files. A user may need to look into this directory to check the existence of certain libraries in case there are compilation or run-time errors.

/usr/sbin

Many system administration commands are placed here.

/usr/share/man

Manual pages for HP-UX commands.
