Common Commands

The command	meaning	instructions
git add -A	Commit all changes to the staging area	Git add — short for all
git ci -m “xxx”	Commit the code for the staging area to the local repository	XXX is a description and CI is short for COMMIT
git pull origin br1	Pull code locally from the remote BR1 branch
git push origin br2	Synchronize the local repository to the BR2 branch of the remote repository
git fetch	Updating remote branches
git br	View all local branches	The * will indicate the current branch, and the color will be different
git br -a	View all branches of the local remote	The red ones are remote branches, and BR stands for branch
git co br1	Switch to the (local) BR1 branch	Co is short for checkout, and an error is reported if there is no local BR1 branch
git co -b br3	Create a new BR3 branch and switch to it
git br -D br1	Delete the local BR1 branch
git push origin –delete br1	Delete the remote BR1 branch
git br -m oldBr newBr	Change the local oldBr branch name to newBr
git remote -v	View the remote corresponding to the local repository
git st	View local modified content (including file addition, modification and deletion)	Content that is not added is red. Content that is added, but not committed, is green
git co .	Undo all file changes and deletions (excluding additions)	The result is a file that has not yet been added
git co aa.js	Undo changes to a file individually	Same as above
git clean -df	Undo all new files	The result is a file that has not yet been added
git reset .	Undoes all content that has been added to the modified, but not yet added, state	Applies to files that have been added, but not yet committed
git log	Print out all commit records	You can view the commitiD and time
git log –pretty=oneline	Commit records have been rendered in a friendlier form	Only commitiD and remarks can be seen
git reflog	Lists records of all Git-related operations	The operation ID can be backcoded
git reset –hard id	Fall back to a version of the code corresponding to the ID	The value can be CommitiD or operation ID
git init	Create a.git folder in the current directory	This is a hidden folder that contains git configuration files, etc
git remote add origin xxx	Associate local and remote repositories	Will write content in the.git directory. The XXX suggestion is a link starting with HTTP
git config –user.name “xxx”	–global is not recommended, because many times you will have multiple Git accounts	Will write to the.git directory
git config –user.email “xxx”	–global is not recommended, because many times you will have multiple Git accounts	Will write to the.git directory

Git add

• Git add -a commits all changes
• Git add -u commits modified and deleted files, excluding new files
• Git add. submit new and modified files, excluding deleted files

git commit -a

-a saves you a git add step at commit time, but only for modifying or deleting files. New files are still git Add or untracked

Establish a connection between the existing folder and the remote repository

1. Open the target folder and run git init to generate a. Git directory.
2. Git config –user.name “XXX” and git config –user.email “XXX” are both optional.
3. Run git remote add origin XXX to associate the local repository with the remote repository.
4. Execute git pull Origin master to pull remote code. Git ci -m “XXX”;
5. You can select Git push -u Origin br1 or Git push Origin br1 for the first remote commit. With -u, you don’t need to add origin master to git pull and git push.

Rollback of files

• If you have already added git, you can run git reset. Git co 7.js can undo changes or deletions of individual files. Git clean-df can be used to delete newly added files
• If it has not been added, you can choose git co. Or git clean-df to undo it

Version back

Git reset –hard ID git reflog can be used to restore the commitiD and the operation ID. Git revert is recommended for multiple branches

Git revert and Git Reset

• Git Revert will create a commit message to undo the changes.
• Git reset returns the commit directly to the specified COMMIT.

Git pull — Rebase origin br1 merges rebase methods and is more secure

The essence of pull is fetch+merge, which can also be added –rebase merges by rebase
