removing something if you committed before add to .gitignore
============================================================ 

https://stackoverflow.com/a/9750651/105282
To stop this you have to do : git rm -r --cached .idea/

adding a remote (if it get zapped)
==================================
# if you have a clone of the repo, this should help with the git url
git remote -v
git remote add origin ssh://user@host:/path/to/repo

find when a file was commited
=============================
git log --diff-filter=A -- src/library/textfiles/irc.txt

removing files from git
=======================

warning1: git-filter-repo may zap your remotes, make a note of them
warning2: git-filter-repo warns you that it expects a clean repo which i did
not have and might have caused warning1.

# on debian (and clones) install as a package
sudo apt install -y git-filter-repo
# we want to remove random.txt in data directory of our current repo
git-filter-repo --path src/random.txt --invert-paths
git push -f

synology as a git server
========================

assumption: you have installed git service on your synology and created a share
called /volume1/GitRepos

creating the repo
-----------------
ssh into synology with a git enabled user
# create a bare repo
cd /volume1/GitRepos
mkdir hello-world
cd hello-world
git init --bare

clone the repo
--------------
git clone ssh://user@host:/volume1/GitRepos/hello-world
