cv - Coreutils Viewer
=====================
What is it?
-----------
This tool can be described as a **Tiny**, Dirty, Linux-and-OSX-Only C command
that looks for coreutils basic commands (cp, mv, dd, tar, gzip/gunzip,
cat, etc.) currently running on your system and displays the
percentage of copied data.
It can now also estimate throughput (using flag `-w`).

_(After many requests: the colors in the shell come from [powerline-shell](https://github.com/milkbikis/powerline-shell). Try it, it's cool.)_
It's probably easy to add a progress, show estimated time, and, with a
bit more work, provide a "top-like" mode with more accurate
information.
How do you build it?
--------------------
make && make install
It depends on library ncurses, you may have to install corresponding packages (may be something like 'libncurses5-dev' or 'ncurses-devel').
How do you run it?
------------------
Just launch the binary, `cv`.
What can I do with it?
----------------------
A few examples. You can:
* monitor all current and upcoming instances of coreutils commands in
a simple window:
watch cv -q
* see how your download is progressing:
watch cv -wc firefox
* look at your Web server activity:
cv -c httpd
* launch and monitor any heavy command using `$!`:
cp bigfile newfile & cv -mp $!
and much more.
How does it work?
-----------------
It simply scans `/proc` for interesting commands, and then looks at
directories `fd` and `fdinfo` to find opened files and seek positions,
and reports status for the largest file.
It's very light, and compatible with virtually any command.
