Note: set up on Chromebook penguin container, but had to skip the config config line that silences untracked files. I suspect git version variation, but working fine so far.

Updated install script on configDotFiles repo to be
curl -sSf https://gist.githubusercontent.com/rudimusmaximus/cbb877cb5797b00d7fbb9ddc88e7f8b9/raw | bash
updated so self deletes at end

updated again, no need for self delete. see echo at end of script.

special handling for .extra file (stop tracking for user to make private local machine changes)

Improved script with it's own version, and updating configDotFiles repo to run with -h flag; then users can repeat the install script with -d for dry run or no flags for live install. Added more checks and error checking. See readme for all changes.

matches configDotFiles v0.3.3

install 2.0.8

as of Sep 30, 2024, this gist is a member file of the rudimusmaximus/configDotFiles repository.

• centralizes the install script and the main repository
• allows users to have a copy to run locally

DO NOT USE THIS ONE ANYMORE....it may be deleted at anytime.
