Clone via [email protected] (ssh)

If using 1 single account or need to create id keys?
# Windows + Linux
ssh-keygen -t rsa -b 4096 -C "[email protected]"
# (-C for adding comment only)
# Enter a file:
# Linux: /home/thi/.ssh/id_rsa
# Windows: C:\Users\dinha\.ssh\id_rsa
# Enter password
Tell who you are
# Tell who you are? (it's global, you may need to set it locally for each repo)
git config --global "Thi Dinh"
git config --global "[email protected]"

In case you have multiple accounts, you have to indicate separatedly the account in each repository,

git config "Thi"
git config "[email protected]"
ssh/config for different accounts

If 2 accounts on 2 different platforms,

# ~/.ssh/config
# Default github account: [email protected]
IdentityFile ~/.ssh/id_rsa
IdentitiesOnly yes

# Other github account: [email protected]
IdentityFile ~/.ssh/id_rsa_ideta
IdentitiesOnly yes

If 2 accounts on the same platforms, eg. Github

Host *
IdentityFile ~/.ssh/id_rsa.thi
AddKeysToAgent yes

Host *
IdentityFile ~/.ssh/id_rsa.ideta
AddKeysToAgent yes
If you use zsh?

It's important on linux, otherwise, you won't be able to use ssh-agent in zsh environment

# ~/.zshrc
plugins=(git ssh-agent)

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa.ideta
ssh-add ~/.ssh/id_rsa.thi
alias ud_ssh='update_ssh'

Everytime you have problems, just ud_ssh.

Reset ssh-agent on terminal
# Delete all cached keys (be careful)
ssh-add -D

# Be careful, it will reset and use different agent!!!!
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa
# ssh-add ~/.ssh/id_rsa_ideta

# Check saved keys
ssh-add -l
# Go to
# copy public key
cat ~/.ssh/
# clone some repo
git clone [email protected]:dinhanhthi/

Repo template

Archived on 14/10/21

I wanna make a theme notetheme2 based on

  1. Make be a template (Go to Settings)

  2. Create a new repo based on this template.

  3. Create a new branch notetheme2 on Make changes on this branch.

  4. Everything we have a "theme change" on, merge it to branch

  5. If there are files (only for files) in you wanna keep, add below line to .gitattributes (under branch before performing the merge,

    # add line to .gitattributes
    echo 'file_name.txt merge=ours' >> .gitattributes
    # on windows, remove `''`
  6. If there are folders (or files) in you don't wanna keep (from /master), just delete them and make a new commit. From this time, later merges will ignore them.

  7. If there are folders in /notethem2 you wanna keep the current state (instead of merging from master), create a script

    # used for branch notetheme2 only
    echo 'Reset some only-this-branch folders after merging.'
    git reset folder_1 folder_2
    git checkout .
    git add .
    git commit -m "update from master"

    Each time you run the merge, run

    git merge master && sh
  8. Update changes from to repo notetheme2[ref].

    # add as a remote
    git remote add template [URL of the template repo]
    # update the changes
    git fetch --all
    # update from template's branch
    git merge template/notetheme2
  9. If there is an error fatal: refusing to merge unrelated histories, try to add --allow-unrelated-histories. There must be conflict.

    # keep remotes
    git merge -X theirs template/notetheme2 --allow-unrelated-histories
    # keep local
    git merge -X ours template/notetheme2 --allow-unrelated-histories
