:a step by step process of how the custom shell, arsine, processes the input command ‘ls -l‘ and returns output in a terminal emulator Co-Authored with: Bobby Yang, follow @glyif on twitter and github. For reference to the code of arsine, it is hosted on github (@glyif , repo simple_shell): https://github.com/glyif/simple_shell These beginning steps until the custom _getline() function all occur for all processes and all inputs into arsine including ls -l, and so therefore, there is no specific explanation of what happens in the case of ls -l until the _getline() function explanations. arguments inventory The major component of the initialization of arsine occurs in a function that builds a struct termed the arguments inventory. This arguments inventory has almost all of the major variables utilized within arsine; also, many of the functions in arsine take the arguments inventory as input parameters. It was a concept that was implemented in […]

:on the kernel | linux vs. unix | operating system vs. ubuntu vs. virtual machine | shell vs. bash | command line vs. terminal As daunting as I imagined the task of writing this article would be, it wasn’t worse than the feeling I continually face of having to learn to program software without a solid grasp of the meaning of the aforementioned components and applications. I often feel confused as to the differences between each of the above listed components and systems. My main problem is that I miss the big picture of how my computer software that I utilize is structured and connected to the rest of my computer. This also creates problems for how I communicate about what I’ve coded on my computer, especially for people that use different software and different machines. Not being able to explain how I’ve been using a computer is at least unflattering and certainly […]
