-h flag usually means human readable format Its a convenient built in conversion in a Linux OS. for example if you went to your command terminal in Linux in my case a raspberry pi and typed df. This will show you your used and available memory. It will show something like you have 448336 bytes. Your probably like huh that's confusing. Now type in df -h (using the -h flag) you should get a result like this 448M instead of 4488336 bytes.
