How to check hard disk size in Linux from shell |
To find the amount of hard disk space and what’s free via the Linux shell use the df command. Here are a few examples:
I have an 80 GB hard drive with only 4% being used. Another check:
On this server there is a 20GB primary drive (see 17691725) that 24% is being used and a backup 40GB drive where 17% is being used for storing shoutcast content files.
An 8GB hard drive with 16% being used.
Conversion
1024 bytes = 1KB
1024 KB = 1 MB (Megabyte)
1024 MB = 1 GB (Gigabyte)
1024 GB = 1 TB (Terabyte)
EXAMPLE. 80GB hard drive = 83,886,080 KB

For linux, df -h is better. It writes it in “easy” viewable for humans.

This isn’t looking at disk size; it is looking at filesystem size. You could very well have a 100Gb disk but only 10Gb allocated to filesystems and nothing in this page explains how to identify the 90% of the disk that is unallocated.
