A number of files are in different places in Mac OS X than in other operating systems. For more information about the Mac OS X layout, read File System Overview. For more information about other operating systems, read the following:

• hier—The Mac OS X manual page hier(7) describes the Mac OS X file-system hierarchy.

• http://www.FreeBSD.org/cgi/man.cgi?query=hier&sektion=7—The FreeBSD manual page hier(7) describes the FreeBSD file-system hierarchy. It is similar to the hierarchy used by most BSD-based operating systems. (No, the spelling of section is not a typo.)

• http://www.pathname.com/fhs/—The Filesystem Hierarchy Standard describes the file system hierarchy used by Linux-based operating systems, and is derived from the hierarchy used by AT&T UNIX-based operating systems.

• http://docs.hp.com/en/B2355-60130/hier.5.html—This appendix from the HP-UX documentation describes the hierarchy of AT&T UNIX-based operating systems.

• http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp?topic=/com.ibm.aix.baseadmn/‍doc/baseadmndita/fs_tree_org.htm—This page in the IBM pSeries and AIX Information Center describes the hierarchy of AIX.
