voronstl/exercises/create_glb_links/README.md

# Goal
Place soft links to the glb files created by Blender in the staging tree in a single directory, ```web/batch_glb_png/glbs,``` , so the glb->PNG converter can easily process a set of files in one directory and not have to navigate the staging tree.

# Introduction
This is a simple run-a-script exercise.  (Note: the name of the link has the complete directory path as part of the link name rather than a 1:1 match of the file name it links to.)

# Steps
In a command console:

     cd ...web/batch_glb_png
     date; time ./link_glbs.sh [PATH to the root directory of your GitHub staging area]

You can verify how many links were created using:

    ...web/batch_glb_png $ ls -la glbs/ |wc -l

Example:

    jlpoole@jp ~/work/Voron/voronstl/web/batch_glb_png $ date; time ./link_glbs.sh /home/jlpoole/work/Voron/test1
    Wed Mar  4 18:51:15 PST 2026
    ROOT:    /home/jlpoole/work/Voron/test1
    OUTDIR:  /home/jlpoole/work/Voron/voronstl/web/batch_glb_png/glbs
    LOG:     link_glbs_20260304_185115.log


    DONE. linked=131 skipped=0
    0 (details in link_glbs_20260304_185115.log)

    real    0m0.507s
    user    0m0.569s
    sys     0m0.263s
    jlpoole@jp ~/work/Voron/voronstl/web/batch_glb_png $ ls -la glbs/ |wc -l
    136
    jlpoole@jp ~/work/Voron/voronstl/web/batch_glb_png $ 

And, the script can be run over-and-over again and not step on previously created links.

Example, see "skipped=131" below:
