System-config is my customizations of Posix systems (Linux/Cygwin/Mac OS X, but mainly Debian Linux or Ubuntu). It aims to reproduce my complete working environment with a single command. I made an introductory video about it on youtube (It’s in Chinese, with English subtitles).

During set-up, system-config will download, install, compile many open source projects that I use frequently.

One of these projects is beagrep. It combines a search engine with grep. It is very useful for reading source code. In fact I use it to read system-config’s own source code (code reading is like solving puzzles, solving puzzles is about looking for answers, and what’s best for looking for answers? Search Engines. Google. Beagrep is a local search engine best tuned for software projects).

How to install

Under Debian Linux or Ubuntu, it’s simple to set up system-config:

git clone https://github.com/baohaojun/system-config/ ~/system-config &&
    ~/system-config/bin/Linux/after-check-out.sh

You probably need to fix some bugs when running after-check-out.sh. And then, make system-config your own by forking it and customizing it.

On non debian systems, or if you don’t have sudo permission, you can try to use Linuxbrew:

git clone https://github.com/baohaojun/system-config/ ~/system-config &&
    ~/system-config/bin/after-co-ln-s.sh && (
        . ~/.bashrc
        install-brew.sh
    )

Install Under Mac/Windows

First, please note that installation under Mac/Windows is not as complete as under Linux.

To install under Windows, you need install Cygwin first, then run this command, and fix the errors that might happen (in most cases, they can be fixed by installing additional cygwin packages).

~/system-config/bin/windows/after-check-out.sh

To install under Mac, you need install HomeBrew first, then run this command, and fix the errors that might happen (in most cases, they can be fixed by: 1. installing additional HomeBrew packages and 2. Changing the PATH environment variable, so that the default command can be forced to use HomeBrew’s version).

For your reference, I have used the following setup in my Mac (you may or may not copy&paste it, since the version numbers might change):

if test "$(uname)" = Darwin; then
    extra_path=(
        /usr/local/Cellar/coreutils/8.30/libexec/gnubin
        /usr/local/Cellar/gnu-getopt/1.1.6/bin
        /usr/local/Cellar/bash/4.4.23/bin
        /usr/local/opt/grep/libexec/gnubin
        /usr/local/opt/findutils/libexec/gnubin
        /usr/local/bin
    )
    export SC_PATH_PREFIX=$(
        for x in "${extra_path[@]}"; do
            echo -n $x:
        done
           )
    if test "$(which grep)" != /usr/local/opt/grep/libexec/gnubin/grep; then
        PATH=${SC_PATH_PREFIX}${PATH}
    fi
fi

PATH-TO-HOMEBREWS-VERSION-OF-BASH ~/system-config/bin/Darwin/after-check-out.sh # The Mac's /bin/bash's version is too low.

There’s some difference between Mac and Windows/Linux, because Mac is a kind of Unix by itself, and it comes with traditional versions of Unix tools, for e.g., Mac’s native readlink(1) command does not support the -f flag, and you must switch to the HomeBrew version. To make it worse, HomeBrew won’t by default replace some important system tools, it will only remind you to make that decision yourself (and it will tell you how-to ONLY ONCE if you really want to replace, so watch the HomeBrew installation output carefully).

Currently, the Mac version of after-check-out.sh will only do a minimun setup (just like after-co-ln-s.sh), if you need to build other software, such as beagrep, you need figure it out by yourself. Mainly it’s only a problem of installing dependent packages from HomeBrew.

How to update

System-config come’s with a script named system-config-update, you can run it to update to the latest version.

How to remove

If you tried system-config and don’t like it, you can run the following command to stop it:

sc stop

Next time, if you want to try again, you can simply run:

sc start

How to completely remove system-config

Unfortunately, there is no clean way to remove system-config and change everything back to the way it was before you installed system-config.

You may run: rm -rf ~/system-config ~/src/github, and reboot to see if everything works the old way.

If not, you may need to re-build your HOME directory or even re-install your Liunx.

See disclaimer.

How to use

You should be able to use system-config just like using any Linux distribution.

But if you want more power, you can watch the youtube video and try to copy whatever that you like.

(If you are in China, note that the video is also uploaded to bilibili.)

How does it work?

Please refer to my github blog, there are quite some articles about system-config. Most are in Chinese though, sorry😅.

Especially this article: How does it work and how to use it.

Disclaimer

System-config started out as a very personal project. If you decided to use it, please do so at your own risk, there is absolutely no warranty of any kind😅.

If you have your own customization, it would be a good idea that you back them up before you try system-config. It’s a good idea that you too put your own customization into a git repo, if you have not done so already.
