Download latest build for Blender 2.7x and 2.8x
How to use:
- get that source code and name it "dlblender"
- change vars INSTALL_PATH and LINK_PATH is you want
- INSTALL_PATH is where will reside new and old version of blender.
I'm using hidden path "~/.blender"
- LINK_PATH is where symbolic link to blender-2.79 and blender-2.80 will reside.
I'm using ~/Apps
- set it executable, and put it in ~/.local/bin or /usr/local/bin (PATH)
Then, call "dlblender" in a terminal
Note:
- I'm detecting CPU architecture to get archives
- actually, not compatible with Mac and Windows, but I can do it later, that's why
I made a function to detect archive type (tar, zip...) and CPU architecture. Right now
I only tested that on my Fedora 28
- If you like it, or want more, maybe I'll create a real repository
