How is a command run in the background in a bash script?

To run a command in the background in a bash script, you simply append an ampersand (&) at the end of the command. Here’s a simple example:

1. Create a bash script, for example background_task.sh:

#!/bin/bash
# A simple script that runs a command in the background
echo "Starting background task..."
sleep 10 &  # This command will run in the background
echo "You can continue using the terminal while the task runs."

2. Make the script executable:

chmod +x background_task.sh

3. Run the script:

./background_task.sh

In this example, the sleep 10 command will run in the background, allowing the script to continue executing and the terminal to remain available for other commands.
