Df

Revision as of 07:39, 9 September 2004

df is acronymic for disk free

When this command is used with no parameters, it will display the amount of disk space free on each mounted device in a 512-byte per block count, as well as a percentage.

You may specify either a device path or plain directory path to retrieve the associated mount-point information. Also, the parameter -h may be used to have the output displayed in 'human-readable' format.
