"Just last week we walked you though a new tool, agedu,
that allows you to get a snapshot view of your file system. agedu
produces a very nice graphical display that provides an overview of
the age and size of your data (either change or access time).
However, there are times when you need or want more detail on the
data that's sitting in your storage. This time around we'll look at
a new tool, FS_scan, that does precisely that.
"FS_scan allows you to recursively scan a directory tree to get
a detailed view of your data. In particular, it will tell you the
dates and ages of your files, the average ages of the files in a
given directory, and it will tell you the oldest files in the
directory tree. It also produces a CSV file that you can open in a
spreadsheet. With this information you can get a very detailed view
of the state of your storage with the ability to do a trend
analysis of the resulting data (i.e. How fast is it changing? How
often are files accessed? How often is data modified?)."
