If you ever need to download an entire website, perhaps for off-line viewing, wget can do the job — for example:

$ wget --recursive --no-clobber --page-requisites --html-extension --convert-links --restrict-file-names=windows --domains website.org --no-parent  www.website.org/tutorials/html/

This command downloads the website www.website.org/tutorials/html/.

The options are:

• --recursive: download the entire website
• --domains website.org: don't follow links outside website.org

First Method

Deleting the .git folder may cause problems in our git repository. If we want to delete all of our commits history, but keep the code in its current state, try this:

# Check out to a temporary branch:
git checkout --orphan TEMP_BRANCH

# Add all the files:
git add -A
