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 accomodate 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
