An exhaustive tutorial on the command line is a bit beyond the scope of the manual. The man command brings up the user manual and can be used to learn more about a commands use, its options and inputs. If you wanted to learn more about the df (disk free) command, enter the following into a command line:
|
|
|
|
.. code::
|
|
|
|
man df
|
|
|
|
This will show you the user manual for the df command containing and explanation of the command and other useful information. For example is the -h option gives a human readable output.
|
|
|
|
.. code::
|
|
|
|
df -h
|
|
|
|
will make a much nicer output than
|
|
|
|
.. code::
|
|
|
|
df
