Application Directories

Directories on the UNIX operating system are arranged in a tree structure format. In a tree structure, all directories (except for the highest-level directory) are subdirectories of another directory, which is called the parent directory. The highest-level directory in UNIX is the root directory; it is designated by a forward slash (/). In the root directory are subdirectories, such as /lawenv/law/lawapp9 (for applications), /usr (for various user functions such as login accounts), /etc (for miscellaneous files), and so on. In each of these directories are files, more subdirectories, or both.

Directory names are separated by a forward slash (/). For example, the full path and directory name for the product line where $LAWDIR equals /lawenv/law and the product line is lawapp9 is /lawenv/law/lawapp9.
