/media : Temporary mount directory is created for removable devices viz., media/cdrom. /lost+found : This Directory is installed during installation of Linux, useful for recovering files which may be broken due to unexpected shut-down. 
/lib : The Lib directory contains kernel modules and shared library images required to boot the system and run commands in root file system.Every time a new user is created, a directory in the name of user is created within home directory which contains other directories like Desktop, Downloads, Documents, etc. /etc : Contains Application’s configuration files, startup, shutdown, start, stop script for every individual program./dev : Contains device files for all the hardware devices on the machine e.g., cdrom, cpu, etc./boot : Holds important files during boot-up process, including Linux Kernel./bin : All the executable binary programs (file) required during booting, repairing, files required to run into single-user-mode, and other important, basic commands viz., cat, du, df, tar, rpm, wc, history, etc.Basics of Linux: Linux Directory Structure Diagram:

Preparing your tools:īefore writing shell scripts (which are collections of Linux commands), we must be first aware of how to use the Linux shell, and how to type and execute commands in and the most important is to have rich knowledge of Linux commands. In this series, we will use the Bash shell.
This is the de facto standard shell for almost all Linux Distributions, like Red Hat, CentOS, Fedora, Ubuntu, etc.
The Bourne Shell, which is the default shell in many UNIX operating systems. What Types of Bash Shell Scripting in a Linux operating system are Available? For instance, the weekly backup that run every Saturday at midnight, the purging of old log files that takes place on the first of every month, and the system monitoring utility that checks the CPU, memory, file systems, paging space utilizations every 10 minutes, and notifies the admin by email, all considered typical usages for the shell scripts combined with crontab job automation. Together, crontab jobs and Bash shell scripting scripts can fully-automate many administration and monitoring tasks. Bash Shell Scripting in a Linux combined with cron jobs:Ĭrontab job is a Unix/Linux tool that helps system administrators schedule jobs to run at specific times on periodic basis. Writing shell scripts half-automates the administration tasks, saves the administrator’s time, and minimizes typos effects. This is much better than having to remember, and type the commands every time the task is needed. In general, when a specific task is frequently needed, it is wise to write a script that can do it for you. So many other tasks can be done using Bash shell scripting scripts. For example, a script could be written to start a database, shutdown a database, start backup, check whether a specific service is up, and if not, it could start it. Why Bash Shell Scripting in a Linux operating system?Īs being set of Linux commands, a shell script can be used to achieve one or more tasks. When the script is to be executed, the Bash shell scripting reads the file contents, interprets and executes them as if they were typed on the shell command prompt. The commands are written and stored in an ordinary text file. What are Bash Shell Scripting in a Linux operating system?Ī Bash shell scripting is a collection of Linux commands to be executed in sequence. A shell is accessed by a terminal which runs it. It is the interface through which a user works on the programs, commands, and scripts. What is Shell?Ī Bash shell scripting in a Linux operating system takes input from you in the form of commands, processes it, and then gives an output. So, let me tell you what Bash shell scripting is. Shell Scripting means writing scripts (programs) for the UNIX/Linux Shell. Shell scripting is a very important skill that Unix/Linux administrators can never go without. In this Bash shell scripting tutorial, we are going to learn Linux Shell Scripting.
