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 which support certain optional commands or packages which use those directories.  Some HP-UX versions add special directories not shown here. 

/Root directory. 

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

/devSpecial files (device files); see mknod(8).

/etcSystem administrative commands and configuration files. 

/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. Administrators may wish to keep them around for later reference.

/libFrequently-used object code libraries and related utilities. 

/lost+found
For connecting detached files; for use by fsck(8).

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

/usersUser home directories; sometimes immediate, sometimes at lower levels. 

/users/guest
Default home directory for user "guest"; see passwd(5). Directory exists for novice users; you may wish to remove it.

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