       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.

       -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 report.

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

       -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

       -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

   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

       -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

       -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

       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
          /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.
