Directory Structure


60/75


What goes whereDirectory Structure

Directory Contents

/bin User binaries

/boot Information required for startup

/dev Devices

/etc The configuration files for the Linux system

/home home directory for most user

/lib Contains system libraries, and some critical files such as kernel modules or

device drivers.

/lib64 Contains system libraries, and some critical files such as kernel modules or

device drivers, on some 64-bit systems.

/lost+found the files that used for a restores after a system crash or when a partition

hasn't been unmounted before a system shutdown. This way you can recover

files that would otherwise have been lost.


61/75



Directory Contents

/media Default mount point for removable devices, such as USB

sticks, media players, etc

/mnt Stands for "mount". Contains filesystem mount points. These

are used, for example, if the system uses multiple hard disks

or hard disk partitions. It is also often used for remote

(network) filesystems, CD-ROM/DVD drives, and so on.

/opt Contains add-on software. Some large program suites may

prefer to be installed here, rather than under /usr

/proc procfs virtual filesystem showing information about

processes as files.


62/75



Directory Contents

/root The home directory for the superuser"root" - that is, the

system administrator. This account's home directory is

usually on the initial filesystem, and hence not in /home

(which may be a mount point for another filesystem).

/srv Server data (data for services provided by system)./tmp Temporary files

/usr Holds executables, libraries, and shared resources that are

not system critical, like the X Window System, KDE, Perl,

etc.

/var A short for "variable." A place for files that may change often

- especially in size, for example e-mail sent to users on the

system, or process-ID lock files.

/sapdata HANA DB data files

/saplogs HANA DB log files


63/75



Directory Contents

/sbin Stands for "system (or superuser) binaries"

and contains fundamental utilities, such as

init, usually needed to start, maintain and

recover the system.

/selinux Security-Enhanced Linux

(SELi-nux) is a Linux feature that provides avariety of security policies, including the U.S.

Department of Defense style of mandatory

access controls, through the use of Linux

Security Modules (LSM)

/software Location for Linux code (not on all

distribution)

/sys a virtual filesystem (sysfs, comparable to

/proc, which is a procfs), which stores and

allows modification of the devices connected

to the system

flexible configuration options and adds

important features to syslog, like usingTCP for transport

Script fi les on Linux

SAP commonly deliveries script fi les that provide valuable functionality.

Often the scripts have a sh or csh extension.

Unless the execution bit is set, you cannot execute these files.

In the example above neither hanaconfig.sh or setup.sh can execute, unt il we

set the execution flag with chmod.
