fileinfo 0.3.3

Show information about files in a tabular fashion.

Downloads ↓

Fileinfo helps you in identifying files with specific values for certain attributes in order to search and sort these files and present the results in an easily readable tabular fashion.

Using fileinfo you can access this information for many files at once without opening these files individually with a dedicated application, which can be very time consuming.

In order to determine such file attributes, fileinfo comes with some pre-built plug-ins, for file formats like PDF, MP3, TTF and PY (Python source code files). These plug-ins allow you to determine e.g. the number of pages or the creator of PDF documents, the artist and title of MP3 files, the number of glyphs in TTF font files, the number of classes or docstrings in Python files, etc.

Of course, you can also access file information on an operating system level, like the size and modification date/time of files. And, you can also write your own plug-ins to extend fileinfo's capabilities.

A tool like fileinfo is different from other tools like Spotlight, since it does not use a huge global index and it presents not only a flat result list, but an overview of matching files together with the respective (possibly sorted) attribute values. And since fileinfo is written in pure Python it is not tied to a specific plattform.

Fileinfo is most useful when used on many files at once, because then you get an overview of the attribute values for the entire set of files.

This release fixes a few buglets and implements minor packaging refactorings.

  • provide a Unittest test suite
  • install test suite inside the installed package
  • test samples include MP3, PDF, TTF and Python files

Examples

From the system command-line you use fileinfo e.g. like this:

$ python fileinfo -a npages *.pdf

Here is an example of some statistics for Python code (taken from the top-level of Docutils 0.5):

$ cd docutils-0.5/build/lib/docutils
$ fileinfo -a lc:nclasses:ndefs:ndocstrs *.py
  lc  nclasses  ndefs  ndocstrs  path
 205         5      2         3  __init__.py
 616         1     24        14  core.py

Here is another example for Mac OS X Widgets:

$ cd /Library/Widgets
$ fileinfo --format rest-simple -a bundlename:bundleversion *.wdgt
