Git
Repository
- create:
git init - clone:
git clone git@host:username/repo.git
Commit
- Commit all changes:
git commit . -m "message" - Add all files, including untracked files:
git add -A - Change message of last commit:
git commit --amend -m "message"
Branch
- create:
git checkout -b new-branch - (CAUTION) reset when broken:
git reset --hard @{u}(DANGER)
Merge and Rebase
Merge = create commit from two parallel tracks of changes; Rebase = Act like changes happened in sequence. Merging is usually faster and works in all situations, but rebase makes the commit history look nicer.
SSH
ssh user@host- Cope to remote:
scp local/file/path user@host:remote/file/path - Cope from remote:
scp user@host:remote/file/path local/file/path - Exiting VIM:
[ESC]:q![enter]
Public key authentication
- More secure and less tedious than password authentication (only one password to remember)
- generate key:
ssh-keygen - copy key to host:
ssh-copy-id user@host
The SSH-agent
If you are using public key authentication and don’t like typing passwords, add this at the end of your .bashrc / .zshrc / .profile (on the client):
eval "$(ssh-agent)"
Next, add into your ~/.ssh/config (create it if it does not exist):
AddKeysToAgent yes
If you wish to use the same key on the remote (for example, with git), also add this:
Host example.com
User username
ForwardAgent yes
