To execute a MongoDB query in a Linux script, you can use the mongo command-line tool provided by MongoDB. Here's how you can do it:

1. Open a terminal.
2. Install the MongoDB shell by following the installation instructions appropriate for your Linux distribution.
3. Create a new script file, for example, script.sh, using a text editor.
4. Add the following lines to the script file, replacing

1
2

#!/bin/bash
mongo  --eval "<QUERY>"

1. Save and close the script file.
2. Make the script file executable by running the following command in the terminal:

1

chmod +x script.sh

1. Optionally, move the script file to a directory on your PATH to make it easily accessible:

1

sudo mv script.sh /usr/local/bin/

1. To execute the MongoDB query, run the script by entering its name in the terminal:

1

./script.sh

The script will execute the MongoDB query using the mongo shell, and the results will be displayed in the terminal.
