How to check disk space usage in Linux

Check free and used disk space per filesystem with df -h, add the type with df -hT, and check inode usage with df -i.

Check how much space each mounted filesystem is using. df -h is the everyday form; -T adds the filesystem type.

# Human-readable space per filesystem
df -h

# Include the filesystem type
df -hT

# A single mount point
df -h /u01

# Inodes instead of bytes
df -i
