Overview

fr - Free Resource Printer

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

It was written because of 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 like this:

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

... in fruity colors. Yes, colors can be turned off, units chosen, etc. fr has been tested on Ubuntu (N, P, Q), CentOS 6, Windows (XP, 7), and Mac OS X (10.7.5) so far.


Install

You'll need pip, but not virtualenv.

Linux

Need pip? On Ubuntu:

sudo apt-get install python-pip

For Red Hat: s/apt-get/yum/. Or follow the manual instructions.

Next, run this:

sudo pip install fr

If you'd like the development version instead:

sudo pip install https://bitbucket.org/mixmastamyk/fr/get/default.zip

As Udisks is not installed by default on Precise Server (and possibly others), it can be installed if you'd like to print volume labels:

sudo apt-get install udisks

Windows

After eight years this script finally supports Windows. ;)

Need pip? Instructions for installing on Windows. Put "%ProgramFiles%\PythonXX\Scripts" in your PATH.

Next, run these as Admin:

pip install colorama        # want color?
pip install fr[win]         # installs necessary winstats

I've given up on Unicode icons (for now) on the Windows console and went back to cp437 for that old-timey DOS feel. Perhaps it should print out "conventional/high" memory too.


Mac OS X

Yes, it supports that too.

sudo pip install -U fr

And off you go.


Use

Run it ;)

fr

And of course there are a number of options:

fr -h

Note: Output will be in a compact format unless the width of the console is at least 90 characters. Give it more and it will expand to fill available space.
