ssh-add -l
ssh-agent -k
eval `ssh-agent`
ssh-add ~/.ssh/id_rsa
ssh-add -l
git push

auto completion when you press tab key try to complete branch name

This is when you type tab key after enter some keyword , e.g. TK-12, which you expect the full branch name e.g. TK-1234-fix to be filled in command line automatically.

brew install bash-completion

fatal: repository 'https://github.com/xxxxx.git/' not found

TL;NR; You can try to change your repository form git to https via

git remote -v
git remote remove origin
git remote add origin https://xxx

Solution

• (1) This is indicate you have no network access to it. It most likely you are running the command behind of corporation firewall. So to check and set two environment variable HTTP_PROXY and HTTPS_PROXY.
• (2) Another reason would be your password or authentication expired, trying to create new token and add to your github account: take a look at : https://docs.github.com/en/authentication/connecting-to-github-with-ssh/adding-a-new-ssh-key-to-your-github-account

You can use either one of below three commands

git diff --name-only --diff-filter=U
git status --short | grep "^UU "
git ls-files -u

One line command to add, commit and push one changed file

git status --short | awk '{split($0, a);print a[2]}' | xargs git add && git commit -m 'commit changes' && git push origin BRANCH_NAME

to show files committed but not pushed

git diff --stat --cached origin/feature/BRANCH_NAME

to view file content changed

git show PATH/abc.sql

show file change logs

git log is the powerful command for this kind of tasks, as below sample commands

git log --pretty=format:"%h [%an] %s" --graph

git log --pretty=format:"%h [%an] %s" --graph --since=7.days

• %h means short hash
• %s is subject

git log --pretty=format:"%h [%an] %s" --graph --since=7.days -S bower.json 
git log --pretty=format:"%h [%an] %s" --graph --since=7.days --grep Npm
git log --pretty=format:"%h [%an] %s" --graph --since=7.days --committer todd

• -S keyword_of_filter_files
