Git advanced usage, take it if you like!

Keywords: Java git Spring npm github

If you think git is confusing, then this copy is for you!

Please note that I intentionally skipped basic commands such as git commit and git pull/push. The theme of this short copy is some "advanced" uses of GIT.

Navigation - jump to previous branch

git checkout -

View history

# Each submission is shown on a single line
git log --oneline

# Search all submission logs for submissions containing "homepage"
git log --all --grep='homepage'

# Get someone's submission log
git log --author="Maxence"

Alas: * * * * reset a commit that you don't want to keep, but now you want to roll back?

#Get all operation history
git reflog

#Reset to corresponding submission
git reset HEAD@{4}
# …… Or
git reset --hard <Hash value submitted>

Ouch: * * * * I made a mess of the local warehouse. How should I clean it up?

git fetch origin
git checkout master
git reset --hard origin/master

View the differences between my branch and master

git diff master..my-branch

Custom submit

#Edit last commit
git commit --amend -m "Better commit log"

#Add some content in the last commit, keep the commit log unchanged. Git add. & & git commit -- amend -- no edit

#Empty commit - can be used to re trigger CI builds
git commit --allow-empty -m "chore: re-trigger build"

Square submit

For example, I want to rebase the last three submissions:

- git rebase -i HEAD~3
-Keep the pick of the first line, and replace the remaining commits with squash or s
-Clean up the commit log and save (type: wq in vi editor to save)

pick 64d26a1 feat: add index.js
s 45f0259 fix: update index.js
s 8b15b0a fix: typo in index.js

correct

For example, I want to add some content to the submission of fed14a4c.

git submit branch

git add .
git commit --fixup HEAD~1
#Or you can replace HEAD~1 with the submitted hash value (fed14a4c)

git rebase -i HEAD~3 --autosquash
#Save and exit the file (input `: wq `) in VI)

Execute commands on each commit when rebase

If there are many features, there may be multiple commits in a branch. If the test fails, you want to find the commit that caused the test to fail. At this point, you can use the rebase --exec command to execute commands on each commit.

#Run the 'npm test' command on the last 3 commits
git rebase HEAD~3 --exec "npm test"

Temporary storage

Staging is more than just git stash and git stash pop;)

#Save all files being tracked
git stash save "log information"

#List all staging items
git stash list

#Get and delete staging items
git stash apply stash@{1}
git stash drop stash@{1}
# …… Or use a command
git stash pop stash@{1}

clear

#Remove a branch that does not exist on the remote warehouse
git fetch -p

#Remove all branches containing 'greenkeeper'
git fetch -p && git branch --remote | fgrep greenkeeper | sed 's/^.\{9\}//' | xargs git push origin --delete

GitHub = Git + Hub

I use Hub as a package of GIT. If you want to do this, you can set an alias: alias git='hub '

#Open the browser to access the warehouse url (GitHub warehouse only) git browse

Bonus: * * * * my favorite git alias

alias g='git'
alias glog='git log --oneline --decorate --graph'
alias gst='git status'
alias gp='git push'
alias ga='git add'alias gc='git commit -v'

# 🤘
alias yolo='git push --force'

#Weekly station meeting report
git-standup() {
 AUTHOR=${AUTHOR:="`git config user.name`"}

 since=yesterday
    if [[ $(date +%u) == 1 ]] ; then
 since="2 days ago"
    fi

 git log --all --since "$since" --oneline --author="$AUTHOR"
}
