LINUX BASH SCRIPTS

Code:

A Linux Bash script is a text file containing a series of commands written in the Bash shell language. It allows you to automate tasks and execute multiple commands sequentially.

To create a Linux Bash script:

1. Open a text editor like `nano`, `vim`, or `gedit`.
2. Start the script with the shebang to specify the interpreter: [code]#!/bin/bash

3. Write your desired commands, one after another.
4. Save the file with a `.sh` extension, for example, `myscript.sh`.
5. Make the script executable using

Code:

chmod +x myscript.sh

.
6. Run the script using

Code:

./myscript.sh

.

Example:

Code:

#!/bin/bash

echo "Hello, World!"
ls -l
mkdir my_folder

This simple script will print "Hello, World!", list files in the directory, and create a new folder.

Remember to add appropriate error handling and comments to make the script more robust and understandable.

Creating Bash scripts can significantly improve your efficiency in Linux system administration and repetitive tasks.
