than when a fatal error occurs. Ncurses will not be initialized until the scan
is complete. When exporting the data with \f(CW\*(C`\-o\*(C'\fR, ncurses will not be

In some cases, the ncurses browser interface which you'll see after the
scan/import is complete may look garbled when using this option. If you're not
exporting to a file, \f(CW\*(C`\-2\*(C'\fR is probably a better choice.
.IP "\-2" 4
.IP "\fB\-2\fR" 4
.IX Item "-2"
Provide a full-screen ncurses interface while scanning a directory or importing
a file. This is the only interface that provides feedback on any non-fatal
errors while scanning.
.IP "\-q" 4
.IX Item "-q"
Quiet mode. While scanning or importing the directory, ncdu will update the
screen 10 times a second by default, this will be decreased to once every 2
seconds in quiet mode. Use this feature to save bandwidth over remote
connections. This option has no effect when \f(CW\*(C`\-0\*(C'\fR is used.

.IP "\fB\-\-enable\-shell\fR, \fB\-\-disable\-shell\fR" 4
.IX Item "--enable-shell, --disable-shell"
Enable or disable shell spawning from the browser. This feature is enabled by
default when scanning a live directory and disabled when importing from file.
.IP "\fB\-\-enable\-delete\fR, \fB\-\-disable\-delete\fR" 4
.IX Item "--enable-delete, --disable-delete"
Enable or disable the built-in file deletion feature. This feature is enabled
by default when scanning a live directory and disabled when importing from
file. Explicitly disabling the deletion feature can work as a safeguard to
prevent accidental data loss.
.IP "\fB\-\-enable\-refresh\fR, \fB\-\-disable\-refresh\fR" 4
.IX Item "--enable-refresh, --disable-refresh"
Enable or disable directory refreshing from the browser. This feature is
enabled by default when scanning a live directory and disabled when importing
from file.
.IP "\fB\-r\fR" 4
.IX Item "-r"
Read-only mode. This will disable the built-in file deletion feature. This
option has no effect when \f(CW\*(C`\-o\*(C'\fR is used, because there will not be a browser
interface in that case. It has no effect when \f(CW\*(C`\-f\*(C'\fR is used, either, because
the deletion feature is disabled in that case anyway.

\&\s-1WARNING:\s0 This option will only prevent deletion through the file browser. It is
still possible to spawn a shell from ncdu and delete or modify files from
there. To disable that feature as well, pass the \f(CW\*(C`\-r\*(C'\fR option twice (see

file browser.

Read-only mode. When given once, this is an alias for \f(CW\*(C`\-\-disable\-delete\*(C'\fR, when
given twice it will also add \f(CW\*(C`\-\-disable\-shell\*(C'\fR, thus ensuring that there is no
way to modify the file system from within ncdu.
.IP "\fB\-\-si\fR, \fB\-\-no\-si\fR" 4
.IX Item "--si, --no-si"
List sizes using base 10 prefixes, that is, powers of 1000 (\s-1KB, MB,\s0 etc), as
defined in the International System of Units (\s-1SI\s0), instead of the usual base 2
prefixes, that is, powers of 1024 (KiB, MiB, etc).
.IP "\-\-confirm\-quit" 4

Requires a confirmation before quitting ncdu. Very helpful when you
accidentally press 'q' during or after a very long scan.
.IP "\-\-color \fI\s-1SCHEME\s0\fR" 4

.IP "\fB\-\-show\-mtime\fR, \fB\-\-hide\-mtime\fR" 4
.IX Item "--show-mtime, --hide-mtime"

in the browser with the 'm' key. This option is ignored when not in extended
mode (see \f(CW\*(C`\-e\*(C'\fR).
.IP "\fB\-\-show\-graph\fR, \fB\-\-hide\-graph\fR" 4
.IX Item "--show-graph, --hide-graph"

the browser with the 'g' key.
.IP "\fB\-\-graph\-style\fR \fI\s-1OPTION\s0\fR" 4
.IX Item "--graph-style OPTION"
Change the way that the relative size bar column is drawn. Recognized values
are \fIhash\fR to draw \s-1ASCII\s0 \f(CW\*(C`#\*(C'\fR characters (default and most portable),
\&\fIhalf-block\fR to use half-block drawing characters or \fIeighth-block\fR to use
eighth-block drawing characters. Eighth-block characters are the most precise
but may not render correctly in all terminals.
.IP "\fB\-\-shared\-column\fR \fI\s-1OPTION\s0\fR" 4
.IX Item "--shared-column OPTION"
Set to \fIoff\fR to disable the shared size column for directories, \fIshared\fR
(default) to display shared directory sizes as a separate column or \fIunique\fR
to display unique directory sizes as a separate column. These options can also
be cycled through in the browser with the 'u' key.
.IP "\fB\-\-sort\fR \fI\s-1COLUMN\s0\fR" 4
.IX Item "--sort COLUMN"
Change the default column to sort on. Accepted values are \fIdisk-usage\fR (the
default), \fIname\fR, \fIapparent-size\fR, \fIitemcount\fR or \fImtime\fR. The latter only
makes sense in extended mode, see \f(CW\*(C`\-e\*(C'\fR.
.Sp
The complete list of currently known pseudo filesystems is: binfmt, bpf, cgroup,
cgroup2, debug, devpts, proc, pstore, security, selinux, sys, trace.
The column can be suffixed with \fI\-asc\fR or \fI\-desc\fR to set the order to
ascending or descending, respectively. e.g. \f(CW\*(C`\-\-sort=name\-desc\*(C'\fR will sort by
name in descending order.

Require a confirmation before quitting ncdu. Very helpful when you accidentally
press 'q' during or after a very long scan.
.IP "\fB\-\-confirm\-delete\fR, \fB\-\-no\-confirm\-delete\fR" 4
.IX Item "--confirm-delete, --no-confirm-delete"
Require a confirmation before deleting a file or directory. Enabled by default,
but can be disabled if you're absolutely sure you won't accidentally press 'd'.
.IP "\fB\-\-color\fR \fI\s-1SCHEME\s0\fR" 4
.IX Item "--color SCHEME"
Select a color scheme. The following schemes are recognized: \fIoff\fR to disable
colors, \fIdark\fR for a color scheme intended for dark backgrounds and \fIdark-bg\fR
for a variation of the \fIdark\fR color scheme that also works in terminals with a
light background.
.Sp
The default is \fIdark-bg\fR unless the \f(CW\*(C`NO_COLOR\*(C'\fR environment variable is set.
.SH "CONFIGURATION"
.IX Header "CONFIGURATION"
Ncdu can be configured by placing command-line options in \f(CW\*(C`/etc/ncdu.conf\*(C'\fR or
\&\f(CW\*(C`$HOME/.config/ncdu/config\*(C'\fR. If both files exist, the system configuration
will be loaded before the user configuration, allowing users to override
options set in the system configuration. Options given on the command line will
override options set in the configuration files. The files will not be read at
all when \f(CW\*(C`\-\-ignore\-config\*(C'\fR is given on the command line.
.PP
The configuration file format is simply one command line option per line. Lines
starting with \f(CW\*(C`#\*(C'\fR are ignored. Example configuration file:

Directory hard links are not supported. They will not be detected as being hard
links, and will thus be scanned and counted multiple times.
Directory hard links and firmlinks (MacOS) are not supported. They will not be
detected as being hard links, and may thus be scanned and counted multiple
times.

Some minor glitches may appear when displaying filenames that contain multibyte
or multicolumn characters.
.PP
The unique and shared directory sizes are calculated based on the assumption
that the link count of hard links does not change during a filesystem scan or
in between refreshes. If it does, for example after deleting a hard link, then
these numbers will be very much incorrect and a full refresh by restarting ncdu
is needed to get correct numbers again.
.PP
All sizes are internally represented as a signed 64bit integer. If you have a
directory larger than 8 EiB minus one byte, ncdu will clip its size to 8 EiB
minus one byte. When deleting items in a directory with a clipped size, the
resulting sizes will be incorrect.
.PP
Item counts are stored in a signed 32\-bit integer without overflow detection.
If you have a directory with more than 2 billion files, quite literally
anything can happen.
.PP
On macOS 10.15 and later, running ncdu on the root directory without
`\-\-exclude\-firmlinks` may cause directories to be scanned and counted multiple
times. Firmlink cycles are currently (1.16) not detected, so it may also cause
ncdu to get stuck in an infinite loop and eventually run out of memory.
minus one byte. When deleting or refreshing items in a directory with a clipped
size, the resulting sizes will be incorrect. Likewise, item counts are stored
in a 32\-bit integer, so will be incorrect in the unlikely event that you happen
to have more than 4 billion items in a directory.
