Introduction to common commands of git

This article is to share with you an introduction to common git commands. The editor thought it was very practical, so I shared it with you to learn. The following information is about the common commands of git.

1) basic environment 1) Local initialization: generate .git directory, do not easily modify the command: git init 2) set signature: distinguish the identity of different developers, the signature set here has nothing to do with the account and password of logging in to the remote library (code center) * Project level / warehouse level: valid only in the current local library scope Command: gitconfig user.name admingit config user.email admin@admin.com information saved location: .git / config file * system user level: login to the current operating system user scope command: gitconfig-- global user.name admingit config-- global user.email admin@admin.com information saved location: ~ / .gitconfig file * level Other priorities: (1) proximity principle: the project level takes precedence over the system user level Use project-level signatures when both exist (2) if there is only a user-level signature of the system, the user-level signature of the system shall prevail; (3) if both of them do not exist, errors will be reported frequently in future operations; 2) the basic operation git status # check the status of the workspace and the staging area git add 123.txt # submit the workspace files to the staging area (either for a single file or using "." Indicates all files in the current directory) git rm-- cached 123.txt # recalls the files in the staging area and replaces them in the workspace git commit-m "first commit 123.txt" # submits the contents of the staging area to the local library (- m description information) 3) several ways to view history git log # View previously submitted log information git log-- pretty=oneline # View previously submitted log information (displayed on one line) git log-- oneline # View previously submitted log information (displayed in a more concise way) git Reflog # shows all historical HEAD pointers 4) controls the version forward and backward

1) Operation based on index value (recommended)

Git reset-- hard d67b2ca #-- hard is followed by the index value queried by the git reflog command

2) use the ^ symbol (only backward)

Git reset-- hard head ^ # back one version (^ one means back one version)

3) use the ~ symbol (only backward)

Git reset-- hard HEAD~n # n means a few steps back. 5) Delete the file and retrieve it.

Premise: before deletion, the status of the file when it exists is submitted to the local library

Action:

Git reset-- hard [pointer position]

1) the deletion operation has been submitted to the local library: the pointer position points to the history

2) the deletion operation has not been submitted to the local library: the pointer position uses HEAD

6) compare file differences git diff [filename] # compare files in the workspace with the cache git diff [historical versions in the local library] [filenames] # compare the files in the workspace with the local library history git diff [historical versions in the local library] # compare all files in the workspace with the local library 7) git branch management

Git branch [Branch name] # create a branch

Git branch-v # View all branches The "*" sign indicates the current branch (the-v option is not added) git checkout [branch name] # switch branch git checkout-b [branch name] # create branch and switch branch git merge [merged branch name] # Quick merge branch (provided that it cannot be on the merged branch) git branch-d [branch name] # Delete specified branch git branch-D [branch name] # force delete specified branch git stash # restore the status of the current version library temporary storage git stash pop # and delete temporarily stored information git stash apply # restore temporarily stored information But do not delete information git stash drop # delete temporary storage information git stash show # view temporary storage information git remote add origin https://github.com/lvzhenjiang-hub/test.git # give the address of the remote warehouse an individual name The name is origingit remote # to see if the current version library belongs to the remote version library git remote-v # View details git push origin master # push the local master branch to the remote repository git checkout-b dev origin/dev # create a local dev branch and associate it to the dev branch git fetch origin master of the remote repository # download from remote warehouse to local git merge origin/master # merge remote branches to git pull origiin master # download master branch of remote warehouse to local And merge, mainly used to resolve conflicts git branch-- set-upstream-to=origin/dev dev associates the local dev branch to the dev branch of the remote repository git branch-r-d origin/dev deletes the specified remote dev branch git push origin: dev submits the deleted remote branch to the remote version repository

This is the end of the common commands about git. I hope the above content can be helpful to you and learn more knowledge. If you like this article, you might as well share it for more people to see.
