This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.
While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

| # Ubuntu 14.04 don't have nsenter - the straight forward way required me to install build tools and etc. | |
| # I preferred to keep the system clean and install nsenter in a container and then copy the command to the host | |
| # Note - its also possible to run nsenter from a container (didn't tried) https://github.com/jpetazzo/nsenter | |
| # start a container | |
| docker run --name nsenter -it ubuntu:14.04 bash | |
| ## in the docker | |
| apt-get update | |
| apt-get install git build-essential libncurses5-dev libslang2-dev gettext zlib1g-dev libselinux1-dev debhelper lsb-release pkg-config po-debconf autoconf automake autopoint libtool |

| # Here short description of this script | |
| # This is just a template to be used for writing new bash scripts | |
| ### | |
| # Based on Google Style Guide: https://google.github.io/styleguide/shell.xml | |
| # General remarks | |
| # * Executables should have no extension (strongly preferred) or a .sh extension. | |
| # * Libraries must have a .sh extension and should not be executable |
| #!/bin/bash | |
| # A simple script to backup an organization's GitHub repositories. | |

| # NOTES: | |
| #------------------------------------------------------------------------------- | |
| # * User @jimklimov (and probably some others called out in the long comment | |
| # thread below) have modified this script to make it more robust and keep | |
| # up with various changes in the GitHub API and response format at: | |
| # https://github.com/jimklimov/github-scripts |
| # replace PAPERTRAIL_HOSTNAME and PAPERTRAIL_PORT | |
| # see http://help.papertrailapp.com/ for additional PHP syslog options | |
