Valid field names are: 'source', 'fstype', 'itotal', 'iused', 'iavail', 'ipcent', 'size', 'used', 'avail', 'pcent', 'file' and 'target' (see info page).

If an argument is the absolute file name of a device node containing a mounted file system, df shows the space available on that file system rather than on the file system containing the device node.

DESCRIPTION         top

This manual page documents the GNU version of df.

OPTIONS         top

Show information about the file system on which each FILE resides, or all file systems by default.

AUTHOR         top

Written by Torbjorn Granlund, David MacKenzie, and Paul Eggert.

Mandatory arguments to long options are mandatory for short options too. The SIZE argument is an integer and optional unit (example: 10K is 10*1024). There is NO WARRANTY, to the extent permitted by law. If you have a bug report for this manual page, see ⟨http://www.gnu.org/software/coreutils/⟩. If no file name is given, the space available on all currently mounted file systems is shown.

FIELD_LIST is a comma-separated list of columns to be included. -a, --all include pseudo, duplicate, inaccessible file systems -B, --block-size=SIZE scale sizes by SIZE before printing them; e.g., '-BM' prints sizes in units of 1,048,576 bytes; see SIZE format below -h, --human-readable print sizes in powers of 1024 (e.g., 1023M) -H, --si print sizes in powers of 1000 (e.g., 1.1G) -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[=FIELD_LIST] use the output format defined by FIELD_LIST, or print all fields if FIELD_LIST is omitted -P, --portability use the POSIX output format --sync invoke sync before getting usage info --total elide all entries insignificant to available space, and produce a grand total -t, --type=TYPE limit listing to file systems of type TYPE -T, --print-type print file system type -x, --exclude-type=TYPE limit listing to file systems not of type TYPE -v (ignored) --help display this help and exit --version output version information and exit Display values are in units of the first available SIZE from --block-size, and the DF_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables.

df command in Linux with examples

This article is a follow up to the previous 90 Linux Commands frequently used by Linux Sysadmins post. -P, --portability use the POSIX output format --sync invoke sync before getting usage info --total elide all entries insignificant to available space, and produce a grand total -t, --type=TYPE limit listing to file systems of type TYPE -T, --print-type print file system type -x, --exclude-type=TYPE limit listing to file systems not of type TYPE -v (ignored) --help display this help and exit --version output version information and exit 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). df displays the amount of space available on the file system containing each file name argument. This is free software: you are free to change and redistribute it. [FILE]... If an argument is the absolute file name of a disk device node containing a mounted file system, df shows the space available on that file system rather than on the file system containing the device node.

Valid field names are: 'source', 'fstype', 'itotal', 'iused', 'iavail', 'ipcent', 'size', 'used', 'avail', 'pcent', 'file' and 'target' (see info page). If no file name is given, the space available on all currently mounted file systems is shown.
