DF(1) General Commands Manual DF(1) NAME df - Show information about the file system on which each FILE resides, or all file systems by default. SYNOPSIS df [--help] [-a|--all] [-B|--block-size] [--total] [-h|--human-readable] [-H|--si] [-i|--inodes] [-k ] [-l|--local] [--no-sync] [--output] [-P|--portability] [--sync] [-t|--type] [-T|--print-type] [-x|--exclude-type] [-V|--version] [paths] DESCRIPTION Show information about the file system on which each FILE resides, or all file systems by default. OPTIONS --help Print help information. -a, --all include dummy file systems -B, --block-size scale sizes by SIZE before printing them; e.g. '-BM' prints sizes in units of 1,048,576 bytes --total produce a grand total -h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G) -H, --si likewise, but use powers of 1000 not 1024 -i, --inodes list inode information instead of block usage -k like --block-size=1K -l, --local limit listing to local file systems --no-sync do not invoke sync before getting usage info (default) --output[=...] [default: source,size,used,avail,pcent,target] use output format defined by FIELD_LIST, or print all fields if FIELD_LIST is omitted. Possible values: o source o fstype o itotal o iused o iavail o ipcent o size o used o avail o pcent o file o target -P, --portability use the POSIX output format --sync invoke sync before getting usage info (non-windows only) -t, --type limit listing to file systems of type TYPE -T, --print-type print file system type -x, --exclude-type limit listing to file systems not of type TYPE -V, --version Print version [paths] EXTRA Display values are in units of the first available SIZE from --block-size, and the DF_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables. Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set). SIZE is an integer and optional unit (example: 10M is 10*1024*1024). Units are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB,... (powers of 1000). Units can be decimal, hexadecimal, octal, binary. VERSION v(uutils coreutils) 0.9.0 2026-05-31 DF(1)
