fducmd, fdu − display the number of disk blocks used per directory or file


fducmd [ −s ] [ −a ] [ −r ] [ filename ... ]

fdu [ −s ] [ −a ] [ −r ] [ filename ... ]


fdu gives the number of kilobytes contained in all files and, recursively, directories within each specified directory or file filename. If filename is missing, ’.’ (the current directory) is used.



Only display the grand total for each of the specified filenames.


Generate an entry for each file. Entries are generated only for each directory in the absence of this option.


Recursively go down in the directory tree and show deeper entries, too. In absence of this option the deeper directory tree branches are only counted belonging to their parent in the top level directory.

fducmd will perform csh file name globbing based on file and directory information obtained from the FSP database.

Since user’s command shells generally cannot do the proper globbing for this program, it is recommended that user defines a shell alias or function to turn off command shell globbing before running this program. csh example:

alias fdu \(set noglob\; exec fducmd \!\*\)
