To monitor disk space quota in a Linux system, you can create a simple shell script that checks disk usage and sends an alert when usage exceeds a specified threshold. Below is an example of a script that accomplishes this task.
### Shell Script to Monitor Disk Space Quota
```bash
#!/bin/bash
# Set the threshold percentage (e.g. 80 for 80%)
THRESHOLD=80
# Get the list of mounted file systems
FILE_SYSTEMS=$(df -h --output=pcent,target | tail
