Human parameters
Many Linux commands that display file sizes, such as the directory lister ls or the display of free disk space df , by default provide a result that is relatively unsuitable for human use.
It also has to be, because many scripts record and process these results of the commands.
Human parameters
However, in order to achieve readable results, many programs have the parameter -h , such as "human", which, for example, outputs the variant "6.2G" instead of "6543449".
So to determine the free space on the hard drive, enter df -h . And you get readable size information.
