Writing a Bash Script

Here’s a simple guide to writing a Bash script:

1. Create a New File: Use a text editor to create a new file. For example, you can use nano or vim:

bash

nano myscript.sh

Add the Shebang: The first line of your script should specify the interpreter. For Bash, use:

bash

#!/bin/bash

Write Your Script: Below the shebang, you can write your commands. For example:

bash

#!/bin/bash
echo "Hello, World!"

Save the File: Save and exit the text editor.

Make the Script Executable: You need to give the script execute permissions:

bash

chmod +x myscript.sh

Run the Script: You can run your script by typing:

bash

1. ./myscript.sh

Example Script

Here’s a simple example of a Bash script that lists files in a directory:

bash

#!/bin/bash
echo "Listing files in the current directory:"
ls -l
