Coreutils Viewer -- 显示Linux命令运行进度的工具

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.
