The Linux Speed Boost!

Oh my, it has been a while since I visited my Blog. While there were few worthy posts which I should have blogged about, that never happened.

Fortunately I came across this great blog post , but wanted to summarize it in one place (the author made me look at several pages to put it together). Say I have a git project called foo.repo which had a subdirectory called bar, that I now want to make its own separate git project called bar.repo. Current state foo.repo/ .git/ bar/ abc/ xyz/ target state foo.repo/ .git/ abc/ xyz/ bar.repo/ .git/ Step 1 : Clone existing repo as desired repo on the local clone $ git clone --no-hardlinks foo.repo bar.repo Step 2: Filter-branch and reset to exclud
