How to create a shell script?

To create a shell script, follow these steps:

1. Open a Terminal: Launch your terminal application.

2. Create a New File: Use a text editor to create a new file. You can use editors like nano, vim, or touch to create the file. For example:

   nano myscript.sh

3. Add Shebang: At the top of your script, add the shebang line to specify the interpreter. For a bash script, use:

   #!/bin/bash

4. Write Your Script: Below the shebang, write the commands you want the script to execute. For example:

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

5. Save and Exit: If you're using nano, save the file by pressing Ctrl+O, then Enter, and exit with Ctrl+X. For vim, press Esc, type :wq, and hit Enter.

6. Make the Script Executable: Change the file permissions to make the script executable:

   chmod +x myscript.sh

7. Run the Script: Execute the script by typing:

   ./myscript.sh

That's it! You've created and run a shell script.
