How to run Layer Stack in Batch Mode with GDAL?

[المشرف العام]

My goal is process fifteen Landsat-8 scenes with three bands. I need to rescale the pixel depth from 16 bit to 8 bit, stack three bands and mosaic all them. This job must be making via open source solutions. Below is my checklist with all experiments that I’ve done thus far.

This is my command list for six scenes:

The looping doesn’t work and the process stops after the first stacked image:
