NAME       df - report file system disk space usageSYNOPSIS       df [OPTION]... [FILE]...DESCRipTION       This  manual  page  documents  the  GNU version of df.  df displays the       amount of disk space available on the file system containing each  file       name  argument.   If  no file name is given, the space available on all       currently mounted file systems is shown.  Disk space  is  shown  in  1K       blocks  by  default, unless the environment variable POSIXLY_CORRECT is       set, in which case 512-byte blocks are used.       If an argument is the absolute file name of a disk device node contain‐       ing  a  mounted  file system, df shows the space available on that file       system rather than on the file system containing the device node.  This       version  of  df  cannot show the space available on unmounted file sys‐       tems, because on most kinds of systems  doing  so  requires  very  non‐       portable intimate knowledge of file system structures.
