--- name: "inndf" section: "8" platform: "linux" package: "inn" version: "2.7.4-4" release: "Arch Linux 2026-11-01" platforms: ["linux"] url: "https://new.carta.tech/inndf" --- # inndf(8) Report free disk, inodes, and overview information ## 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)](/innwatch.ctl/5.md) and [innstat(8)](/innstat/8.md), and now also reports various other usage information about INN's storage that [df(1)](/df/1.md) doesn't understand. **inndf** doesn't sync, forks less, and is generally less complicated than [df(1)](/df/1.md). 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)](/innstat/8.md), 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 ``` Report the free inodes in *pathnews* and *pathspool* in a format designed for human readability: ``` inndf -i ``` The same, but also add in all file systems in *pathetc*/filesystems: ``` inndf -i -F ``` Print out the number of overview records and the percentage space used by a buffindexed overview database: ``` inndf -no ``` ## HISTORY **inndf** was written by Ian Dickinson \. This manual page was written by Swa Frantzen \. Thanks also to the following folks for ports, patches, and comments: ``` Mahesh Ramachandran Chuck Swiger Sang-yong Suh Brad Dickey Taso N. Devetzis Wei-Yeh Lee Jeff Garzik ``` and to all the other folks I met and worked with during my 10 years as a newsadmin. 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 \. ## SEE ALSO [df(1)](/df/1.md), [innwatch.ctl(5)](/innwatch.ctl/5.md), [innstat(8)](/innstat/8.md).
