September 2012. This is a small C library to use
|
||||
L<libdbus|http://www.freedesktop.org/wiki/Software/dbus> with
|
||||
L<libev|http://software.schmorp.de/pkg/libev.html>. It will register IO
|
||||
watchers, timeout handlers, a dispatch function and a wakeup function on behalf
|
||||
of libdbus. You may have to ensure that the right headers are being included in
|
||||
dbusev.c, in my case the "global.h" does that.

Load the given file, which has earlier been created with the C<-o> option. If

I<FILE> is equivalent to C<->, the file is read from standard input.
|
||||
|
||||
For the sake of preventing a screw-up, the current version of ncdu will assume
|
||||
that the directory information in the imported file does not represent the
|
||||
filesystem on which the file is being imported. That is, the refresh and file
|
||||
deletion options in the browser will be disabled.

||||
|

|

|
||||
Scan the given directory.
|

=item -o I<FILE>
|
||||
|
||||
Export all necessary information to I<FILE> instead of opening the browser
|
||||
interface. If I<FILE> is C<->, the data is written to standard output. See the
|
||||
examples section below for some handy use cases.
|
||||
|
||||
Be warned that the exported data may grow quite large when exporting a
|
||||
directory with many files. 10.000 files will get you an export in the order of
|
||||
600 to 700 KiB uncompressed, or a little over 100 KiB when compressed with
|
||||
gzip. This scales linearly, so be prepared to handle a few tens of megabytes
|
||||
when dealing with millions of files.

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

=head1 EXAMPLES
|
||||
|
||||
To scan and browse the directory you're currently in, all you need is a simple:
|
||||
|
||||
ncdu
|
||||
|
||||
If you want to scan a full filesystem, your root filesystem, for example, then
|
||||
you'll want to use C<-x>:
|
||||
|
||||
ncdu -x /
|
||||
|
||||
Since scanning a large directory may take a while, you can scan a directory and
|
||||
export the results for later viewing:
|
||||
|
||||
ncdu -1xo- / | gzip >export.gz
|
||||
# ...some time later:
|
||||
zcat export.gz | ncdu -f-
|
||||
|
||||
To export from a cron job, make sure to replace C<-1> with C<-0> to suppress
|
||||
any unnecessary output.
|
||||
|
||||
You can also export a directory and browse it once scanning is done:
|
||||
|
||||
ncdu -o- | tee export.file | ./ncdu -f-
|
||||
|
||||
The same is possible with gzip compression, but is a bit kludgey:
|
||||
|
||||
ncdu -o- | gzip | tee export.gz | gunzip | ./ncdu -f-
|
||||
|
||||
To scan a system remotely, but browse through the files locally:
|
||||
|
||||
ssh -C user@system ncdu -o- / | ./ncdu -f-
|
||||
|
||||
The C<-C> option to ssh enables compression, which will be very useful over
|
||||
slow links. Remote scanning and local viewing has two major advantages when
|
||||
compared to running ncdu directly on the remote system: You can browse through
|
||||
the scanned directory on the local system without any network latency, and ncdu
|
||||
does not keep the entire directory structure in memory when exporting, so you
|
||||
won't consume much memory on the remote system.
|
||||
|
||||
|
||||
=head1 HARD LINKS
|
||||
|
||||
Every disk usage analysis utility has its own way of (not) counting hard links.
