TLDR
Display all filesystems and their disk usage
$ df
Display filesystems in human-readable form$ df -h
Display the filesystem for a specific path$ df [path/to/file_or_directory]
Include statistics on free inodes$ df -i
Display filesystems excluding specific types$ df -x squashfs -x tmpfs
Display filesystem types$ df -T
SYNOPSIS
df [-h] [-i] [-T] [-x type] [file...]
DESCRIPTION
df (disk free) displays the amount of disk space available on filesystems. By default, it shows all mounted filesystems with their total size, used space, available space, and usage percentage.
PARAMETERS
-h, --human-readable
Print sizes in human-readable format (K, M, G)-H, --si
Print sizes using powers of 1000 (not 1024)-i, --inodes
Show inode information instead of block usage-T, --print-type
Print filesystem type-t, --type type
Limit listing to filesystems of specified type-x, --exclude-type type
Exclude filesystems of specified type-a, --all
Include dummy filesystems-l, --local
Limit listing to local filesystems--total
Print a total line-P, --portability
Use POSIX output format
CAVEATS
Sizes shown may differ from actual file sizes due to filesystem overhead and reserved space. Some filesystems reserve space for root that won't show as available to regular users.
HISTORY
Part of GNU Coreutils. The df command originated in Version 1 AT&T UNIX in 1971.
