Copy the script below and paste into VM $.$sh text file.

Go to the Linux Documents directory.

Either create a linux$\_$lab.sh text file either in vim or nano OR drag$-$and$-$drop a notepad text file onto the Linux VM$.$

If you dropped and dragged a Windows text file onto the Linux VM you must change the extension on the file to $.$sh and SED out the carriage returns. You run "sed $-$i $\text{'}$s$/\backslash$r$//\text{'}$ linux$\_$lab.sh in a Terminal CLI. You must also do this if you cut and pasted Windows notepad text into a Linux file.

If you create the script in either vim or nano you do not need to SED the file.

NOTE:$$nano linux$\_$lab.sh

This will open the nano text editor where you can paste your script. Here's an example script:

#$!/$bin$/$bash

# This is an example script

echo "Hello, World!"

Save and exit the editor $($Ctrl$+$O to save, Ctrl$+$X to exit in nano$).$

Run and study the output the $.$sh script from the command line.

Make the Script Executable

After creating the script, you need to make it executable. You can do this using the chmod command:

chmod $+$x linux$\_$lab.sh

This command gives execute permission to the script file.

Run the Script

Once the script is executable, you can run it using the following command:

$./$linux$\_$lab.sh

The $./$ prefix RELATIVE PATH tells the terminal to execute the script from the current directory.

$/$home$/$User$01/$linux$\_$lab.sh ABSOLUTE PATH tells the terminal to start from the top of the Linux file system.

You can run the Script with a Specific Interpreter If the script has the #$!/$bin$/$bash shebang $.$

bash example$\_$script.sh

Step summary:

Make sure the script has execute permissions $($chmod $+$x$).$

The script should start with a shebang $($#$!/$bin$/$bash$)$ to specify the interpreter $($optional but recommended$).$

If you're running the script in a different directory, use the full path to the script or cd into the directory containing the script first.

Paste a copy of the resulting output in a new text file.

Copy the resulting output $($including the original command line$)$ and paste it in a new text file.

The script includes:

$$The three execution types:

sequential

recursive $($iterative$,$ looping$)$ including a program test loop not only command recursion option

conditional
