slitherbox | Drop-in pure-Python replacement for common shell utilities

Installation and uninstallation of slitherbox is simple, and will not overwrite any existing utilities on your system. slitherbox uses the same trick as BusyBox, in that symbolic links representing different commands are made to the main slitherbox script. The main script is aware of what name it was run with and executes the corresponding utility. You only need Python 3 and git to install slitherbox. The slitherbox symlinks can be removed by running $ sb_uninstall, restoring use of your native utilities. To re-enable slitherbox, do step 2 again. You can view a list of available commands by running $ sb_list. slitherbox commands can also be run without installing the symlinks by running the slitherbox script directly: $ ./slitherbox <command> [args...].
Clone this repository to the desired installation directory.
Run $ ./slitherbox sb_install. This will create symlinks in the installation directory.
Add the installation directory to the beginning of your $PATH so your shell finds slitherbox commands before it finds your native system commands. For example, you could do this by adding $PATH = ['/path/to/slitherbox'] + $PATH to your .xonshrc if you use xonsh.
Verify the installation was successful by running $ which echo and observing that the resulting path is inside the installation directory.
You can now run all slitherbox utilities from your shell. If you run a command that is not implemented in slitherbox, but does exist elsewhere in your path, then the existing native utility will still be run.
