How to find the true amount of usable free hard drive space?
by grumpyskeptic from LinuxQuestions.org on (#4SVHM)
I am using Linux Mint 17.3 Rosa Cinnamon.
I would like to know the actual amount of usable space I have left on my hard disk, that I can use store files.
The file manager Nemo says I have 5.4gb.
Disk Usage Analyser says I have 30.3gb.
Something called "Disks" says I have exactly 30gb.
Question please:
What is the reliable console command that I can use to find the amount of usable hard drive space I have left?
I think my HD is nearly full, so only Nemo is likely to be correct. Before I removed some large files, I kept getting low disk space warnings.
Thanks.
