Bash Scripting Tutorial by Brian Fox

Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. Bash can be run on most UNIX-like operating systems, including Linux, macOS, and BSD. Bash is a powerful programming language that can be used to perform complex tasks and operations on Linux systems.

In this tutorial, we will cover the basics of bash scripting and how to write simple scripts to automate common tasks on Linux systems.

Bash is a powerful shell that provides a wide range of features for both programmers and system administrators. In this bash scripting tutorial, we will learn how to use the bash shell to write simple scripts and programs. We will also learn how to use some of the more advanced features of bash such as loops, conditionals, and functions.

What is Bash

Bash is a command processor that typically runs in a text window where the user types commands that cause actions. Bash can also read and execute commands from a file, called a shell script. A shell script is simply a text file containing one or more commands.

When such a file is executed by bash, the commands in the script are executed as if they were typed at the keyboard. Bash has several features that make it different from other command processors. One is that it allows variables and functions to be defined and used within scripts.

Another is its ability to redirect input and output from/to files or devices. Finally, bash supports “globbing” which allows wildcard characters to be used to match filenames (e.g., *.txt matches all files with names ending in “.txt”).

How Do I Install Bash

If you’re using a Mac, Bash is already installed. To check the version of Bash that you have, open Terminal and type bash –version. If you see something like 3.2.57(1)-release, then you have Bash 3.2.

If it says 4.4.23(2)-release, then you have Bash 4.4 installed.. To install or update to the latest version of Bash on Linux, head to the GNU Radio website and download the source code for the current release from here (make sure to select ‘Download Source Code’).

Once the tarball has been downloaded, unpack it with tar -xzf bash-*.tar.gz and change into the resulting directory with cd bash-*. Now we need to configure Bash so that it will compile properly on our system by running .

/configure –prefix=/usr/local . Note that if your system doesn’t have /usr/local/bin in its PATH environment variable, you may need to specify a different prefix during this step./configure –help lists all available options./configure should take just a few seconds to run and should end with something like: Once configuration is complete, we can compile and install Bash by running make && make install .

This process will take a minute or two depending on how fast your computer is.. Assuming everything went according to plan, typing which bash at the command line should now return /usr/local/bin/bash . To start using your new version of Bash, simply open a new terminal window or tab.

. Bash is now installed!
