durep - disk usage report generator
durep [OPTIONS]... [DIRECTORY]
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.
Limit text report on directories to depth N. No directories
below this level will be shown in the report.
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 report.
Display the modification date of the file or directory in the
Do not sort results by size. Leaves results in the order in
which they were scanned, which is highly dependent on the file
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.
These options control load and save files.
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).
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.
Give a description to be stored in the save-file. This is
displayed on the web report summary page.
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
These options control which directories and files should be included in
Do not descend into sub-directories, only report files.
Do not traverse file systems. This is similar to the -x option
for du, allowing easy checking of an entire file system such as
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
Ignore paths that match PATTERN. This works in a similar manner
to "-cp" above, except it excludes the directory from the scan
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
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
3. durep -x -cp "/(etc|usr/share)" -ep "/var" -sf
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.
