.::: Troubleshoot Cannot Run Command df, df -kh Hang on Redhat/Rhel, Linux, FreeBSD :::.

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  containing a  mounted  file  system, df shows the space available on that file system rather than on the file system containing the device node (which is always the root file system).  This version of df cannot show the space available on unmounted file systems, because on  most  kinds  of  systems  doing  so requires very nonportable intimate knowledge of file system structures.

     

1. User root cannot run command df -kh
