I was recently asked to "post a batch file/script that would run the configure and build exactly as you do, on a clean command prompt, in order to reproduce your issue" what does this mean in layman's terms? What is a batch file/script?
Bash is the default / most used shell used in most Unixes.. there are others, like csh, zsh, etc.. but in most cases, when you install a new system, bash is the default.
