How to write a basic shell script?

To write a basic shell script, follow these steps:

Open a Text Editor: You can use any text editor like nano, vim, or a graphical editor.
Start with a Shebang: The first line should specify the interpreter. For a Bash script, use:
```
#!/bin/bash
```
Write Your Commands: Below the shebang, write the commands you want the script to execute. For example:
```
echo "Hello, World!"
```
Save the File: Save the file with a .sh extension, for example, myscript.sh.
Make the Script Executable: Run the following command in the terminal to make your script executable:
```
chmod +x myscript.sh
```
Run the Script: Execute the script by typing:
```
./myscript.sh
```

Here’s a simple example that lists files in the current directory and prints a message:

#!/bin/bash

# Print a message
echo "Listing files in the current directory:"

# List files
for file in *; do
    echo "$file"
done

This script will print a message and then list all files in the current directory when executed.
