NAME

hier − file system hierarchy

DESCRIPTION

The following outline gives a quick tour through a representative HP-UX directory hierarchy.  Some of the directories listed only appear with HP-UX versions that support certain optional commands or packages that use those directories.  Some HP-UX versions add special directories not shown here. 

/ Root directory. 

/bin Frequently-used commands and those required to boot, restore, recover, and/or repair the system. 

/dev Special files (device files); see mknod(1).

/etc

/etc/newconfig New (updated) versions of customizable (localizable) configuration files and shell scripts.  Shipped here so as not to overwrite current versions.  Copied to regular locations for newly installed systems.  System administrators may wish to keep them for later reference. 

/lib Frequently-used object code libraries and related utilities. 

/lost+found For connecting detached files; for use by fsck(1).

/rbin An analog to /bin for users in the restricted environment of rsh(1).

/tmp Place to put temporary files (those normally with short lifetimes and which may be removed without notice). 

/users User home directories; sometimes immediate, sometimes at lower levels. 

/users/guest Default home directory for user "guest"; see passwd(4). Directory exists for novice users; you may wish to remove it.

/usr Less-frequently-used commands and other miscellaneous things; historically, often a separate, mounted volume.
