You might have already used Linux shell commands interactively, but how do you go from interactive terminal use to non-interactive workflow with scripts? This course is oriented on those who want to start using BASH programming fully and use terminal efficiently.
We expect that course participants are familiar with the shell basics (experience with BASH, ZSH, etc). We somewhat touch the Part 1 of the Linux Shell tutorial, and continue to Part 2. Though we expect that participant knows how to create a directory and can edit file from the linux shell command line. We will be scripting a lot, there will be lots of demos and real practicing.
