Welcome to  /usr/.
|
| Directory | Description |
|---|---|
| /usr/bin/ | Common utilities, programming tools, and applications. |
| /usr/home/user/ | Home directory of an user |
| /usr/include/ | Standard C include files. But on GhostBSD without content |
| /usr/jails/ | Jails build upon the chroot(2) concept, which is used to change the root directory of a set of processes. This creates a safe environment, separate from the rest of the system. Processes created in the chrooted environment can not access files or resources outside of it. For that reason, compromising a service running in a chrooted environment should not allow the attacker to compromise the entire system. However, a chroot has several limitations. It is suited to easy tasks which do not require much flexibility or complex, advanced features. Over time, many ways have been found to escape from a chrooted environment, making it a less than ideal solution for securing services. |
| /usr/lib/ | Archive libraries |
| /usr/lib32/ | lib32 contains 32-bit libraries, which are required to run any i386-targeted binary, such as wine |
| /usr/libdata/ | Miscellaneous utility data files. |
| /usr/libexec/ | System daemons and system utilities executed by other programs. |
| /usr/local | Local executables and libraries. Also used as the default destination for the FreeBSD ports framework. Within /usr/local, the general layout sketched out by hier(7) for /usr should be used. Exceptions are the man directory, which is directly under /usr/local rather than under /usr/local/share, and the ports documentation is in share/doc/port.
|
| /usr/obj/ | Architecture-specific target tree produced by building the /usr/src tree.
|
| /usr/ports/ | The GhostBSD Ports Collection (optional). |
| /usr/sbin/ | System daemons and system utilities executed by users. |
| /usr/share/ | Architecture-independent files. |
| /usr/src/ | BSD and/or local source files. |
