total, used, free = shutil.disk_usage("/")

# Number of Read and write operations

# 'Disks: XXXXXX/xxG read, XXXX/xxG written.'

For ubuntu machines, -l option doesn't support on top command. It throws this error
top: unknown option 'l' Usage: top -hv | -bcHiOSs -d secs -n max -u|U user -p pid(s) -o field -w [cols]
Can you know hoe to fix this?

Hey @PrashanthAdurugatla
Sorry about that. The script was created with mac-os in mind. I'll look for a solution and update it to work for ubuntu.
In the meantime, you can comment out lines 8, 19, 20, 21, and 28-31
