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 is a program which does this. It does basically the same sort of disk scan
as du, but it also records the last-access times of everything it scans. Then it
builds an index that lets it efficiently generate reports giving a summary of
the results for each subdirectory, and then it produces those reports on demand.
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
