.\" way too many mistakes in technical documents.

.SH "NAME"
inndf \- Report free disk, inodes, and overview information
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBinndf\fR [\fB\-Fhi\fR] [\fB\-f\fR \fIfilename\fR] \fIdirectory\fR [\fIdirectory\fR ...]
.PP
\&\fBinndf\fR \fB\-n\fR
.PP
\&\fBinndf\fR \fB\-o\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBinndf\fR was originally a replacement for \f(CW\*(C`df | awk\*(C'\fR in \fBinnwatch.ctl\fR\|(5)
and \fBinnstat\fR\|(8), and now also reports various other usage information about
\&\s-1INN\s0's storage that \fBdf\fR\|(1) doesn't understand.  \fBinndf\fR doesn't sync, forks
less, and is generally less complicated than \fBdf\fR\|(1).
.PP
Its default behavior is to report free kilobytes (not disk blocks), or
free inodes if \fB\-i\fR 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.
.PP
If \fIenableoverview\fR is set to true in \fIinn.conf\fR, \fBinndf\fR can also be
used to get information about the overview database.  With the \fB\-n\fR
option, it reports a count of the total number of overview records stored.
With \fB\-o\fR, it reports the percentage of space used in the overview
database (for those overview methods where this is meaningful data).
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-f\fR \fIfilename\fR" 4
.IX Item "-f filename"
\&\fIfilename\fR should contain a list of directories to use in addition to
those given by the arguments, one per line.  Blank lines and anything
after \f(CW\*(C`#\*(C'\fR on any line are ignored.
.IP "\fB\-F\fR" 4
.IX Item "-F"
Like \fB\-f\fR except that the filename is \fIpathetc\fR/filesystems and it is
not an error if this file doesn't exist.  (This option is used primarily
by such things as \fBinnstat\fR\|(8), so that the news administrator can add
additional file systems to check to \fIpathetc\fR/filesystems without having
to modify the script.)
.IP "\fB\-h\fR" 4
.IX Item "-h"
Print a usage message and exit.
.IP "\fB\-i\fR" 4
.IX Item "-i"
Report the number of free inodes rather than the amount of free disk
space.
.IP "\fB\-n\fR" 4
.IX Item "-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.
.IP "\fB\-o\fR" 4
.IX Item "-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.
.SH "EXAMPLES"
.IX Header "EXAMPLES"
Print the free kilobytes in \fIpathspool\fR as a simple number:
.PP
.Vb 1
\&    inndf <pathspool in inn.conf>
.Ve
.PP
Report the free inodes in \fIpathnews\fR and \fIpathspool\fR in a format
designed for human readability:
.PP
.Vb 1

.Ve
.PP
The same, but also add in all file systems in \fIpathetc\fR/filesystems:
.PP
.Vb 1
\&    inndf \-i \-F <pathnews> <pathspool>
.Ve
.PP
Print out the number of overview records and the percentage space used by

Katsuhiro Kondou added the \fB\-n\fR and \fB\-o\fR options.  Russ Allbery added
reporting of percentage free disk space.  Support for \fB\-f\fR and \fB\-F\fR was
