A program to print resources in delicious flavors.

Project description

fr is a command-line tool to print free resources in delicious flavors. In short, fr is to free as htop is to top.

fr was written due to unhappiness with the bare-bones, hard-to-read free command. I wanted something a bit more… graphical. Instead of this:

             total       used       free     shared    buffers     cached
Mem:       4045216    2159764    1885452          0     192404     942944
-/+ buffers/cache:    1024416    3020800
Swap:            0          0          0

You’ll see something more like this:

Free Resources in Blocks of 1 Megabyte (1,000,000 bytes)

… in fruity colors if you so choose. Yes, color can be turned off (NO_COLOR environment variable is supported), units chosen, network mounts filtered, etc, etc.

fr 3.x has been tested on Ubuntu 18.04 Bionic “Tch-tch-tch-tch…”, Windows 7, and MacOS 10.13 “High Sierra,” so far.

Note

Version 3.x of fr has been ported and works only under Python 3.6 and over. To use with an earlier version of Python, try fr 1.x, which supports Python 2.7 and earlier platforms.

Install

Linux

As of fr version 3.x, Dbus and Udisks are no longer required or used on Linux. Rather, data is read from the /proc, /dev, and potentially /sys filesystems.

To install system-wide as root:

sudo -H pip3 install fr

Per user (add /home/$USER/.local/bin to PATH):

pip3 install --user fr

Windows

Support is still experimental. Could use some help as Win7 in a VM is all I have access to these days.

Run as Admin:

pip3 install fr[win]    # installs winstats, colorama

or a user install, but need to add the install folder to PATH:

pip3 install --user fr[win]

Mac OS X

Yes, it supports that too. Support is experimental as well:

[sudo] pip3 install [--user] fr

And off you go.

FYI, the Unicode block characters look a bit better with Source Code Pro as the terminal font.

Could use some help here also, borrowing a Mac is my only option. Currently runs sysctl, vm_stat, and df under the hood, hoping there are better options?

Limitations

Optical, Network, Removable

Both Windows and Mac OS are not currently able to detect whether extended properties of filesystems. The port to Python 3 seems to have broken Windows in that regard, which used to work.

Unicode

I’ve given up on Unicode icons (for now) on the Windows console and went back to ASCII. Perhaps it should print out “conventional/high” memory too.

The Linux console (the real boot up console, pre-X) has a very limited character set and therefore uses ASCII as well.

Colors

Windows and the Linux (non-X11) console are limited to sixteen colors. Apparently Windows 10 has been upgraded support more, but I haven’t yet found documentation on how to utilize it.

Use

Run it ;)

fr

And of course there are a number of options, spit out when this is typed:

fr -h

Note

Output will be in a compact format when the width of the terminal/console is under 90 characters. Give it more and it will expand to fill available space.

Release Notes

  • 3.0b5 - MacOS, filter /private/… by default.
  • 3.0b4 - Readme fixes for PyPI.
  • 3.0a0 - Major rewrite to support Python 3.6, refactor shitty thirteen year-old code, remove deps on Dbus and Udisks. Still needs a lot of work.
