durep - disk usage report generator




durep creates disk usage reports with bar graphs, allowing one to easily deduce which
directories are using the most space. Although durep can produce text output similar to
du, its real power lies in the ability to store reports in a file, which can then be
viewed as a web page with the supplied cgi script.


Options are grouped into three distinct sections.

Text Output Options
These options are for controlling the text report output.

-td, --text-depth=N
Limit text report on directories to depth N. No directories below this level will
be shown in the report.

-hs, --hide-size=N[bkmg]
Do not display entries using N Bytes/KB/MB/GB or less (default Bytes). This is to
reduce clutter in the reports. It allows you to remove small files from the text

-sd, --show-date
Display the modification date of the file or directory in the report.

-ns, --nosort
Do not sort results by size. Leaves results in the order in which they were
scanned, which is highly dependent on the file system.

-q, --quiet
Do not produce text output. This stops the creation of a text report, and is useful
when you are only interested in generating a save-file for use with the web report.

File Options
These options control load and save files.

-sf, --save-file=FILE
Save the results of the scan into this file. This can be loaded for a text report,
but is generally used by the cgi script to display web reports. The filename should
end in .ds (it is appended if it does not).

-lf, --load-file=FILE
Load the results of a scan from this file. This takes the place of scanning a
directory. Inclusion options (described below) will not take effect if this option
is used.

-d, --desc=DESCRIPTION
Give a description to be stored in the save-file. This is displayed on the web
report summary page.

-c, --collate==DIR
Collate the save-files in the given directory. This creates a durep.cds file, which
is used by the cgi script to manage and display save-files. See Web Reports section
below for more detail.

Inclusion Options
These options control which directories and files should be included in the report.

-f, --files
Do not descend into sub-directories, only report files.

-x, --one-file-system
Do not traverse file systems. This is similar to the -x option for du, allowing
easy checking of an entire file system such as /.

-cp, --collapse-path=PATTERN
Hide entries below paths that match PATTERN. This allows you to conceal the
contents of certain directories in the report. You may wish perhaps to show home
directories in a report but not show their content in which case you could use the
option "-cp '/home'".

-ep, --exclude-path=PATTERN
Ignore paths that match PATTERN. This works in a similar manner to "-cp" above,
except it excludes the directory from the scan itself.

-cf, --coalesce-files==N[bkmg]
Coalesces entries for files below the given size into one entry. This is useful for
reducing clutter in reports.


Since version 0.9, durep no longer directly generates html files for its web reports. It
now uses a cgi script that reads data from save-files. The script will handle multiple
save-files, potentially from multiple hosts, so you can consolidate your reports into one
place. Copying save-files from other hosts is left as an exercise for the reader.

It is necessary to collate the save-files before viewing them via the cgi script. This
process creates the file "durep.cds" which contains meta-data about all of the save-files.
From this a summary page is shown where you can choose which report you wish to view. The
collation must be done any time a save-file is added or overwritten.

The cgi-script has some configurable variables at the top. These tell the script where to
look for the css file and the graphic used for the bar graphs. There are also options to
set whether the modification date, and/or the options used to create the save-file should
be shown. These are both set to 1 by default.

As always, you should take care when installing the cgi script. I've done my best, but I
make no guarantees about its security. It would probably be unwise to allow this script to
be accessed from the Internet at large.


1. durep -td 2

This would print the directory tree starting from the current directory to depth 2.

2. durep -f /var/spool/mail

This might be useful for keeping a check on the mail directory. The "-f" switch tells
durep to just scan files and not descend into directories.

3. durep -x -cp "/(etc|usr/share)" -ep "/var" -sf /var/lib/durep/root.ds /

This more complicated version does the following. It scans the root file system only,
collapses the contents of any paths beginning /etc or /usr/share and skips the contents
of the /var directory. It saves the output of this report into the file
/var/lib/durep/root.ds. No text report is produced.

4. durep -lf /var/lib/durep/root.ds -hs 1m

This reads the save-file /var/lib/durep/root.ds and produces a text report from it,
hiding any files below 1 megabyte.

5. durep -c /var/lib/durep

This collates any save-files in /var/lib/durep.
