progress - Coreutils Progress Viewer

What is it

This tool can be described as a Tiny, Dirty 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 also show estimated time and throughput, and provides a "top-like" mode (monitoring).

(After many requests: the colors in the shell come from powerline-shell. Try it, it's cool.)

progress works on Linux, FreeBSD and macOS.

Formerly known as cv (Coreutils Viewer).

How do you install it

On deb-based systems (Debian, Ubuntu, Mint, etc.) run:

apt install progress

On archlinux, run:

pacman -S progress

On rpm-based systems (Red Hat, CentOS, Fedora, SUSE, etc.), run one of these:

dnf install progress
yum install progress

On macOS, with homebrew, run:

brew install progress

On macOS, with MacPorts, run:

port install progress

How do you build it from source

make && make install

On FreeBSD, substitute make with gmake.

It depends on library ncurses, you may have to install corresponding packages (may be something like 'libncurses5-dev', 'libncursesw6' or 'ncurses-devel').

How do you run it

Just launch the binary, progress.

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 progress -q
```
see how your download is progressing:
```
  watch progress -wc firefox
```
look at your Web server activity:
```
  progress -c httpd
```
launch and monitor any heavy command using $!:
```
  cp bigfile newfile & progress -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.
