./sysutils/agedu, Utility for tracking down wasted disk space

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 20180522.5b12791, Package name: agedu-20180522.5b12791, Maintainer: pkgsrc-users

Suppose you're running low on disk space. You need to free some up, by finding
something that's a waste of space and deleting it (or moving it to an archive
medium). How do you find the right stuff to delete, that saves you the maximum
space at the cost of minimum inconvenience?

Unix provides the standard du utility, which scans your disk and tells you which
directories contain the largest amounts of data. That can help you narrow your
search to the things most worth deleting.

However, that only tells you what's big. What you really want to know is what's
too big. By itself, du won't let you distinguish between data that's big because
you're doing something that needs it to be big, and data that's big because you
unpacked it once and forgot about it.

Most Unix file systems, in their default mode, helpfully record when a file was
last accessed. Not just when it was written or modified, but when it was even
read. So if you generated a large amount of data years ago, forgot to clean it
up, and have never used it since, then it ought in principle to be possible to
use those last-access time stamps to tell the difference between that and a
large amount of data you're still using regularly.

agedu does same disk scan as du, but also records the last-access times of
everything. Then it builds an index that lets it efficiently generate reports
giving a summary of the results for each subdirectory.

Log message:
Update to r9723 (no changelog). Some highlights from the svn log:

* Add the --files option, to list individual files in the various
  reporting modes.
* Flexibly report sizes in Kb, Mb, Gb etc as appropriate. The
  previous fixed Mb was inconvenient at both ends. Original patch
  from James Beal, though I've polished it pretty much into
* Make the existing -d (depth) option apply to the -H (static HTML
  report) mode, transforming its output from a single HTML file
  giving a report for one directory with no crosslinks to a collection
  of HTML files with crosslinks between them.
* Introduce a --cgi mode, to make it easy to plumb agedu's web
  reporting into an existing web server as an alternative to running
  a dedicated one of its own.
* Switch all the HTML-based reporting modes (the internal httpd, the CGI
  mode and the dump of static HTML files) to using URIs and filenames
  based on the text of the pathname being reported on, rather than
  its numeric index in the data file. The aim is that sub-URIs
  should remain valid when the data is updated - if, for instance,
  you're running the agedu CGI script permanently and changing the
  data file under it every so often.
* Suggestion from James Beal: support a '--title' option to override the
  'agedu:' prefix at the start of the title of output web pages.
