Troubleshooting & Solution

Firstly, to list private key accessible to the agent

ssh-add -l

Then edit following file to remove those unexpected token files

code ~/.ssh/config

Lastly, try to delete files and then push files

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.


This is because your don’t install or something wrong to the bash-completion, just run

brew install bash-completion

remote: Repository not found.

git pull
remote: Repository not found.
fatal: repository '' 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


  • (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 :

Checkout remote branch and keep track

git checkout --track origin/bugfix/fix-branch

Script bible

To show changed file in git log

 git log --raw 

Mac Shells

To show what shell you are using.

echo $0
chsh -s /bin/bash
chsh -s /bin/zsh


To list current shell

ps -p $$

brew command not found issues

You are pretty sure homebrew is installed but can’t find this command when you run brew somewhere.


This is generally lated to different shell installed, such as zsh or oh-my-zsh in M1 chipset MacBook.


Firstly change your shell to zsh

chsh -s /bin/zsh

Secondly, open the file ~/.zshrc and add following line at end of the file

eval $(/opt/homebrew/bin/brew shellenv)

to list merge conflicts files in command line

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

Get correct branch name

Sometimes, if you checkout new branch with incorrect case. It still can check it out to local but you’ll get errors when you try to push it to remote.

To solve this issue, please use following command to get correct branch to checkout

git fetch && git for-each-ref | grep -i 'THE KEY WORD'  | awk '{split($0,a);print a[3]}'
git checkout -b BRANCH_NAME_FROM_ABOVE
