Introduction: Git is widely adopted due to its good distributed characteristics. This article will review the key instructions at its core.
Create Branch
git checkout -b ‘branch name’
View remote branches
git branch -a
Options:
-a View all branches
-r View remote branches
-l View local brnach
View local branch branch
git branch
switch branch
git checkout ‘branch_name’
delete local branch
git branch -D br_name
delete remote branch
git push origin :br (with a space after origin)
Submit an instruction
Add files to Git management
git add xxx.java
Submit to the local Repository
git commit -m ‘comment here’ xxx.java ….
-m : Here are mainly comments for submitting code changes
-a: Refers to submitting a list of all changed files at one time
push instruction
Push to master on remote host
git push origin master
Push the current branch to the remote Repository
git push origin
Push all local branches to the server
git push –all origin
fetch instruction
Meaning: Download the remote code to the local, do not merge
git fetch origin master
View the difference between the local master and the remote master
git log -p master..origin/master
Merge code
git merge origin/master
Another more explicit approach is when the remote code is downloaded to the local as a branch, and then merged
git fetch origin master:t-branch
git diff t-branch
git merge t-branch
Pull command
Download remote code to local and merge it automatically
git pull origin master
In general, it is recommended to use fetch, and decide whether to merge with the remote master code according to the actual situation.
Tag instruction
Create Tag
git tag -a ‘tag_name_v0.1.2’ -m ‘comment message’
Query all current tags
git day
Query Tags by pattern matching
git tag -l ‘v0.1.*’
Push the current specific tag to the remote
git push origin tag_name
Push all current tags to remote
git push origin –all tags
Merge command
switch to master branch
git checkout master
will merge xxx_branch to master
git merge xxx_branch
View git master information
git remote show origin
* remote origin
Fetch URL: http://source.xx.com/app/xx-ImageService.git
Push URL: http://source.xx.com/app/xx-ImageService.git
HEAD branch: master
Remote branch:
master tracked
Local branch configured for 'git pull':
master merges with remote master
Local ref configured for 'git push':
master pushes to master (fast-forwardable)- 1
