A tool for searching the filesystem

ff

About

ff is a tool for searching the filesystem. It was originally inspired by fd.

NOTE: ff is in the early stages of development, expect things to break and syntax to change.

Summary

ff is a tool for searching the filesystem. Its scope is similar to find(1) and fd(1) but it tries to be more accessible and easier to use than find and and more versatile and powerful than fd. It is inspired by and borrows many ways of doing things from fd. It is written in Python >= 3.6.

Features

• Search by file attributes and file metadata(!).
• Simple yet powerful expression syntax.
• Flexible output options.
• Flexible sort options.
• Extendable by user plugins.
• Parallel search and processing.

Examples

Store all files from the current directory that are tracked by git(1) in a tar(1) archive:

$ ff type=f git.tracked=yes --sort --exec-batch tar cvzf git-tracked.tar.gz

Find files in the directory Videos/ that end with .mkv or .mp4 and are between 720 and 1080 pixels high:

$ ff Videos/ {{ ext=mkv or ext=mp4 }} and {{ height+=720 and height-=1080 }}

More examples are here.

Installation

To build and install ff simply type:

$ python setup.py install

This installs the python sources, the ff script, the man page and a set of plugins.

To build a slightly faster version of ff you can use cython:

$ CYTHONIZE=yes python setup.py install

Developing plugins and debug mode

There is a template for new plugins to start from (plugin_template.py) with exhaustive instructions and comments, so you can develop plugins for your own needs.

Useful in that regard is ff's debug mode. It can be activated by starting ff as a script using the python executable:

$ python /usr/bin/ff --debug info,cache ...

Debug mode produces lots of messages which can be limited to certain categories using the --debug category1,category2,... option. On top of that, debug mode activates many internal checks using assert(). Therefore, it is advisable to use debug mode during plugin development.
