In this video, three main topics are covered in details:
1- Shells and their role in file execution.
2- file permissions and "chmod" command.
3- making executable files in binaries versus making shell/python scripts into executable files.
Although this video is a part of a shell-scripting tutorial series, it is prepared in a way that could be used solely and as an independent tutorial.
