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 Arch Linux, run:
pacman -S progress
On Fedora, run:
dnf install progress
On openSUSE, run:
zypper 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 the library ncurses, you may have to install corresponding packages (maybe 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.
(*) on macOS, it does the same thing using libproc
