.Interactive login shell.This is used when logging in to a machine, invoking Bash with the-login option or when logging in to a remotemachine with SSH.“ Ordinary” interactive shell.This is normally the case when starting xterm, konsole,gnome-terminal or similar tools.Non-interactive shell.This is used when invoking a shell script at the command line.Depending on which type of shell you use, different configuration filesare being read. The following tables show the login and non-login shellconfiguration files.

DirectoryContents/Root directory—the starting point of the directory tree./binEssential binary files, such as commands that are needed by both thesystem administrator and normal users. Usually also contains theshells, such as Bash./bootStatic files of the boot loader./devFiles needed to access host-specific devices./etcHost-specific system configuration files./homeHolds the home directories of all users who have accounts on thesystem. However, root's home directory is not located in/home but in /root./libEssential shared libraries and kernel modules./mediaMount points for removable media./mntMount point for temporarily mounting a file system./optAdd-on application software packages./rootHome directory for the superuser root./sbinEssential system binaries./srvData for services provided by the system./tmpTemporary files./usrSecondary hierarchy with read-only data./varVariable data such as log files./windowsOnly available if you have both Microsoft Windows. and Linuxinstalled on your system. Contains the Windows data.The following list provides more detailed information and gives someexamples of which files and subdirectories can be found in thedirectories.

/binContains the basic shell commands that may be used both by rootand by other users. These commands include ls,mkdir, cp, mv,rm and rmdir./bin also contains Bash, the default shell inSUSE Linux Enterprise Server./bootContains data required for booting, such as the boot loader, thekernel, and other data that is used before the kernel begins executinguser-mode programs./devHolds device files that represent hardware components./etcContains local configuration files that control the operation ofprograms like the X Window System. The /etc/init.dsubdirectory contains scripts that are executed during the bootprocess./home/ usernameHolds the private data of every user who has an account on the system.The files located here can only be modified by their owner or by thesystem administrator. By default, your e-mail directory and personaldesktop configuration are located here in the form of hidden files anddirectories. KDE users find the personal configuration data for theirdesktop in.kde4, GNOME users find it in.gconf. Note: Home Directory in a Network EnvironmentIf you are working in a network environment, your home directory maybe mapped to a directory in the file system other than/home./libContains the essential shared libraries needed to boot the system andto run the commands in the root file system. The Windows equivalent forshared libraries are DLL files./mediaContains mount points for removable media, such as CD-ROMs, USB sticksand digital cameras (if they use USB).

/mediagenerally holds any type of drive except the hard drive of your system.As soon as your removable medium has been inserted or connected to thesystem and has been mounted, you can access it from here./mntThis directory provides a mount point for a temporarily mounted filesystem. Root may mount file systems here./optReserved for the installation of third-party software.

Optionalsoftware and larger add-on program packages can be found here./rootHome directory for the root user. The personal data of rootis located here./sbinAs the s indicates, this directory holds utilitiesfor the superuser.

/sbin contains the binariesessential for booting, restoring and recovering the system in additionto the binaries in /bin./srvHolds data for services provided by the system, such as FTP and HTTP./tmpThis directory is used by programs that require temporary storage offiles. Important: Cleaning up /tmp at Boot TimeData stored in /tmp are not guaranteed to survivea system reboot. It depends, for example, on settings in/etc/sysconfig/cron./usr/usr has nothing to do with users, but is theacronym for UNIX system resources. The data in/usr is static, read-only data that can be sharedamong various hosts compliant with the Filesystem Hierarchy Standard(FHS).

This directory contains all application programs and establishesa secondary hierarchy in the file system. KDE4 and GNOME are alsolocated here. /usr holds a number ofsubdirectories, such as /usr/bin,/usr/sbin, /usr/local, and/usr/share/doc./usr/binContains generally accessible programs./usr/sbinContains programs reserved for the system administrator, such as repairfunctions./usr/localIn this directory the system administrator can install local,distribution-independent extensions./usr/share/docHolds various documentation files and the release notes for yoursystem. In the manual subdirectory find an onlineversion of this manual. If more than one language is installed, thisdirectory may contain versions of the manuals for different languages.Under packages find the documentation included inthe software packages installed on your system. For every package, asubdirectory/usr/share/doc/packages/ packagenameis created that often holds README files for the package and sometimesexamples, configuration files or additional scripts.If HOWTOs are installed on your system/usr/share/doc also holds thehowto subdirectory in which to find additionaldocumentation on many tasks related to the setup and operation of Linuxsoftware./varWhereas /usr holds static, read-only data,/var is for data which is written during systemoperation and thus is variable data, such as log files or spoolingdata.

For an overview of the most important log files you can findunder /var/log/, refer to.Every script should contain a Shebang line (this is already the casewith our example above.) If a script does not have this line, you haveto call the interpreter manually.You can save the script wherever you want. However, it is a good ideato save it in a directory where the shell can find it. The search pathin a shell is determined by the environment variablePATH. Usually a normal user does not have write accessto /usr/bin. Therefore it is recommended to saveyour scripts in the users' directory /bin/.

Theabove example gets the name hello.sh.The script needs executable permissions. Set the permissions with thefollowing command.
