/grant [<user>]
/grant [-list|<user>]
Grant someone a slot. This allows the user to download from you even if
you have no free slots. The slot will be granted for as long as ncdc
stays open. If you restart ncdc, the user will have to wait for a regular
slot. Unless, of course, you /grant a slot again.

will have to wait for a regular slot. Unless, of course, you /grant a
slot again.
To get a list of users whom you have granted a slot, use `/grant' without
arguments or with `-list'. Be warned that using `/grant' without argu‐
ments on a PM tab will grant the slot to the user you are talking with.
Make sure to use `-all' in that case.
Note that a granted slot is specific to a single hub. If the same user is
also on other hubs, he/she will not be granted a slot on those hubs.

filelist_maxage <interval>
The maximum age of a downloaded file list. If a file list was downloaded
longer ago than the configured interval, it will be removed from the
cache (the fl/ directory) and subsequent requests to open the file list
will result in the list being downloaded from the user again. Recognized
suffices are 's' for seconds, 'm' for minutes, 'h' for hours and 'd' for
days. Set to 0 to disable the cache altogether.
flush_file_cache <boolean>
Tell the OS to flush the file (disk) cache for file contents read while
hashing and uploading. On one hand, this will avoid trashing your disk
cache with large files and thus improve the overall responsiveness of
your system. On the other hand, ncdc may purge any shared files from the
cache, even if they are still used by other applications. In general, it
is a good idea to enable this if you also use your system for other
things besides ncdc, you share large files (>100MB) and people are not
constantly downloading the same file from you.

HARD LINKS
Every disk usage analysis utility has its own way of (not) counting
hard links. There does not seem to be any universally agreed method of
handling hard links, and it is even inconsistent among different ver-
sions of ncdu. This section explains what each version of ncdu does.

There does not seem to be any universally agreed method of handling hard links,
and it is even inconsistent among different versions of ncdu. This section

ncdu 1.5 and below does not support any hard link detection at all:
each link is considered a separate inode and its size is counted for
every link. This means that the displayed directory sizes are incorrect
when analyzing directories which contain hard links.

that the displayed directory sizes are incorrect when analyzing directories

ncdu 1.6 has basic hard link detection: When a link to a previously
encountered inode is detected, the link is considered to have a file
size of zero bytes. Its size is not counted again, and the link is
indicated in the browser interface with a 'H' mark. The displayed
directory sizes are only correct when all links to an inode reside
within that directory. When this is not the case, the sizes may or may
not be correct, depending on which links were considered as "duplicate"
and which as "original". The indicated size of the topmost directory
(that is, the one specified on the command line upon starting ncdu) is
always correct.

ncdu 1.7 has improved hard link detection. Each file that has more than
two links has the "H" mark visible in the browser interface. Each hard
link is counted exactly once for every directory it appears in. The
indicated size of each directory is therefore, correctly, the sum of
the sizes of all unique inodes that can be found in that directory.
Note, however, that this may not always be same as the space that will
be reclaimed after deleting the directory, as some inodes may still be
accessible from hard links outside it.

BUGS
Directory hard links are not supported. They will not be detected as
being hard links, and will thus be scanned and counted multiple times.
