Python script to monitor disk space on Windows, Linux, and macOS involves using cross-platform libraries and system-specific commands. Here’s a detailed guide on how to achieve this:
1. Introduction
Monitoring disk space is crucial for system administrators and users to avoid running out of storage, which can lead to various issues. This article will guide you through creating a Python script that works across Windows, Linux, and macOS.
2. Prerequisites
- Python installed on your system (Python 3.x is recommended).
- Basic knowledge of Python programming.
- Familiarity with the command line on your operating system.
3. Cross-Platform Compatibility
The psutil library in Python provides an easy way to retrieve information about system utilization (such as CPU, memory, disks, network, sensors) in a cross-platform way. We will use this library to monitor disk space.
Sample code
import psutil
import sys
def check_disk_space():
partitions = psutil.disk_partitions()
for p in partitions:
print(f"Checking partition: {p.device}")
try:
usage = psutil.disk_usage(p.mountpoint)
except PermissionError:
# This can happen on some systems
continue
print(f" Total Size: {usage.total / (1024 * 1024 * 1024)} GB")
print(f" Used: {usage.used / (1024 * 1024 * 1024)} GB")
print(f" Free: {usage.free / (1024 * 1024 * 1024)} GB")
print(f" Percentage: {usage.percent}%\n")
def main():
print("Disk Space Monitor\n")
check_disk_space()
if __name__ == "__main__":
main()
The script will display information about each partition, including its total size, used space, free space, and the percentage of space used.
