NAME

       inndf - Report free disk, inodes, and overview information

SYNOPSIS

       inndf [-Fhi] [-f filename] directory [directory ...]

       inndf -n

       inndf -o

DESCRIPTION

       inndf was originally a replacement for "df | awk" in innwatch.ctl(5) and innstat(8), and now also reports
       various other usage information about INN's storage that df(1) doesn't understand.  inndf doesn't sync,
       forks less, and is generally less complicated than df(1).

       Its default behavior is to report free kilobytes (not disk blocks), or free inodes if -i is used, in the
       file systems holding the directories given on the command line.  (A kilobyte in this case is 1024 bytes.)
       If only one directory is given, the output will be a simple number; if more than one directory is given,
       the output will be formatted for human readability.

       If enableoverview is set to true in inn.conf, inndf can also be used to get information about the
       overview database.  With the -n option, it reports a count of the total number of overview records
       stored.  With -o, it reports the percentage of space used in the overview database (for those overview
       methods where this is meaningful data).

OPTIONS

       -f filename
           filename should contain a list of directories to use in addition to those given by the arguments, one
           per line.  Blank lines and anything after "#" on any line are ignored.

       -F  Like  -f  except that the filename is pathetc/filesystems and it is not an error if this file doesn't
           exist.  (This option is used primarily by such things as innstat(8), so that the  news  administrator
           can add additional file systems to check to pathetc/filesystems without having to modify the script.)

       -h  Print a usage message and exit.

       -i  Report the number of free inodes rather than the amount of free disk space.

       -n  Report  the  total  number  of records in the overview database.  Note that crossposted articles will
           have one overview record for each newsgroup they're posted to.

       -o  Report the percentage usage of the overview database space.  This is  only  meaningful  for  overview
           methods  that  pre-allocate  a  certain amount of space rather than grow to accommodate more records.
           Currently, this flag is only useful for the buffindexed overview method.

EXAMPLES

       Print the free kilobytes in pathspool as a simple number:

           inndf <pathspool in inn.conf>

       Report the free inodes in pathnews and pathspool in a format designed for human readability:

           inndf -i <pathnews> <pathspool>

       The same, but also add in all file systems in pathetc/filesystems:

           inndf -i -F <pathnews> <pathspool>

       Print out the number of overview records  and  the  percentage  space  used  by  a  buffindexed  overview
       database:

           inndf -no

       Katsuhiro Kondou added the -n and -o options.  Russ Allbery  added  reporting  of  percentage  free  disk
       space.  Support for -f and -F was added by Fabien Tassin <fta@sofaraway.org>.
