A command-line tool to print free resources in delicious flavors.

Project Description

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 (1.2X on Precise-Trusty, 1.3X Wily), CentOS 6, Windows (XP, 7), and Mac OS X (10.9.x) so far. It runs only under Python 2.X at this time.


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

use udisks2 if on Wily or later.


Windows

After eight years this script finally supports Windows, though support is experimental. ;)

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, though support is experimental:

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.
