durep - disk usage report generator
durep [OPTIONS]... [DIRECTORY]
creates disk usage reports with bar graphs, allowing one to easily
deduce which directories are using the most space. Although durep
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
Options are grouped into three distinct sections.
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
- -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.
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
These options control which directories and files should be included in the
- -f, --files
- Do not descend into sub-directories, only report
- -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 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.
- durep -td 2
This would print the directory tree starting from the current directory to
- 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
- 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.
- 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.
- durep -c /var/lib/durep
This collates any save-files in /var/lib/durep.
