Question
What are the differences between the following commands?
df
df -h
df -l
Feedback
Information is greatly appreciated. Thank you.
First of, df
reports file system disk space usage. That is, it displays the total size, the used and available space for each of your mounted partitions.
df
is the default behavior, without arguments. Sizes are given in 1K-blocks (that is, 1024 bytes). Local filesystems (i.e., on hard drives on the present machine) as well as remote filesystems (e.g., mounted via NFS on a network) are listed.
df -h
tells df
to display sizes in Gigabyte, Megabyte, or Kilobyte as appropriate, akin to the way a human would describe sizes. Actually, the h
stands for "human-readable".
df -l
tells df
to display only local filesystems, but no remote ones.
df
- disk space shown in 1K blocks
df -h
- disk space shown in human readable form (KB, MB, GB)
df -l
- limit listing to local file systems
This info can be found in man pages. Try man df
.
Type in terminal for each command you want to know :
man <the command>
it will list its usage and options .
in your example type man df
man
before asking here. It may save your time.
