Git 速记 October 12, 2018 / 8 min read
一直想写 Git 的笔记, 但是 Git 知识点太零散了, 并且 Git 又太强大了, 常用/不常用操作随便搜索一下就可以在爆栈网上找到.
所以在这里记录一下自己常用 git 操作.
All in one
Add
$ git add . # add current dir all changes and untracked
$ git add * # add new or modified even ignored but not add deleted change
$ git add file # add file
$ git add -A # same as add .
Delete
$ git add abc # or git rm abc
$ git rm --cached new_file # make new_file from staged to unstaged
Status
$ git st # alias for git status
$ gst # alias in oh-my-zsh
Commit
$ git ci -m ' bla.... ' # alias
Push
$ git push # push to current branch
$ git push --set-upstream origin master # first push
$ git push -u origin master # same above
Show remote address
Show branches
$ git branch -a # see remote branch too
$ git branch -a -v # see branch with commit
Branches
$ git checkout master # change to master branch
$ git checkout -b new_branch # create new branch
$ git branch new_branch && git checkout new_branch # same above
$ git push -u origin new_branch # push to origin
$ git branch -d feature/login # delete local
$ git push origin --delete feature/login # delete origin
$ git fetch && git checkout new_branch # checkout remote branch
Create branch based on old commit
$ git branch new_branch 1a08cbf # same above
checkout remote branch
$ git checkout new_branch
$ git checkout -b test <name_of_remote>/test
$ git checkout -t <name_of_remote>/test
Stash
$ git stash # stash all changes (untracked)
stash@ {0} : WIP on master: 049d078 added the index file
stash@ {1} : WIP on master: c264051 Revert " added file_size "
stash@ {2} : WIP on master: 21d80a5 added number to log
$ git stash pop # first in last out (move out stash)
$ git stash apply # Like pop, but do not remove the state from the stash list.
$ git stash drop # delete last, these two equal to pop
Log
$ git lg # alias lg for log
$ git lg origin/master # show origin master log
lg = log --graph --abbrev-commit --decorate --all --format=format:'%C(bold blue)%h%C(reset) - %C(bold cyan)% aD%C(dim white) - %an%C(reset) %C(bold green)(%ar)%C(reset)%C(bold yellow)%d%C(reset)%n %C(white)%s%C(reset)'
Log line history
$ git log --pretty=short -u -L 155,155:git-web--browse.sh # -u for patch, -L for line range
tag
$ git tag # list all tags
$ git tag -l " v1.8.5* " # list all similarly v1.8.5
$ git tag v1.1 # add v1.1 to current commit
$ git tag -a v1.2 -m ' my version 1.2 ' # add Annotated tag and message
$ git tag -a v1.3 9fceb02 # tag commit 9fceb02 to v1.3
$ git push origin v1.5 # push to origin v1.5
$ git push origin --tags # push all tags
$ git tag -d v1.4-lw # delete tag
$ git push origin :refs/tags/v1.4-lw # delete tag remote
$ git checkout -b version2 v2.0.0 # new branch version2 of v2.0.0 tag
$ git reset --hard v2.0.0 # reset to v2.0.0 tag commit
Checkout
## git checkout [<tree-ish>] [--] <pathspec>…
$ git checkout file # change file back to unchanged state
$ git checkout -- file # same above, -- to differentiate file or branch
$ git checkout 7de7c6d a # change file to 7de7c6d state
$ git checkout 7de7c6d . # change current dir file to 7de7c6d state
Clean
$ git clean -n # list what would deleted
fatal: clean.requireForce defaults to true and neither -i, -n, nor -f given ; refusing to clean
$ git clean -f -d # remove directories
$ git clean -fd # same above
$ git clean -f -X # remove ignored files
$ git clean -fX # same above
$ git clean -f -x # remove ignored and non-ignored files
$ git clean -fx # same above
Diff
$ git diff # diff current working tree and the index
$ git diff filename # diff file
$ git diff --cached # diff staged and HEAD
$ git diff --cached filename # diff file in stage and HEAD
$ git diff ffd98b2 b8e7b00 # diff two commit
$ git diff ffd98b2:filename b8e7b00:filename # diff file with two commit
Show
Merge
$ git merge dev # merge dev to master
Rebase
[branch_name]$ git rebase # rebase current to branch.<branch_name>.remote
$ git rebase master topic # same above
would be:
Advanced
$ git rebase --onto master next topic
would be:
Revert
Revert some existing commits
---o----o---------o-----o----> master
$ git commit -m " revert3 "
----o------o-----------o----------> master
reset
$ git reset # opposite of `git add` (only file change, if file add, using `git rm --cached`)
$ git reset --soft HEAD^ # take off last commit
same above:
$ git branch topic/wip # create new branch
$ git reset --hard HEAD~3 # make master back to old 3 commit (HEAD -> master)
$ git checkout topic/wip # go on working on new branch (HEAD -> topic/wip)
如果上例中在 reset --hard
之前没有创建 branch, 那么这3条 commits 会丢失, 想要找回需要用 reflog
查看 commit<sha1>
, 再 reset --hard <sha1>
:
82bffc2 HEAD@{ 0 }: reset: moving to HEAD^
02ca477 (HEAD - > tmp ) HEAD@{ 1}: commit: append a
$ git reset --hard 02ca477

patch
create patch
$ git format-patch 2fba5b6^..dc131a9 # spawn 3 patch files
$ git format-patch master --stdout > tmp.patch # current branch diff master patch
$ git format-patch 2fba5b6^..dc131a9 --stdout > tmp.patch # `2f` to `dc` (attention the caret after `2f`)
$ git diff > diffs # for unstaged changes
$ git diff --cached > diffs # for staged changes
check the patch
$ git apply --stat tmp.patch # look at what changes are in the patch
$ git apply --check tmp.patch # if no errors, the patch can be applied cleanly
apply the patch
apply patches
$ git am --signoff < tmp.patch
In you git log, you’ll find that the commit messages contain a “Signed-off-by” tag. This tag will be read by Github and others to provide useful info about how the commit ended up in the code.
apply diff outputs
.gitignore
有关.gitigore中*.json 为何能递归匹配所有文件夹下 json 文件的讨论.
ignore 某文件夹下所有文件: node_modules/
ignore 所有 json 类型文件: *.json
排除某 json 不被 ignore: !abc.json
re-ignore already ignored file
$ git rm -r --cached . && git add . # alias reignore
workflow
$ git add . && git ci -m " some work " # a
git rebase <upstream>
If <upstream>
is not specified, the upstream configured in branch.<name>
.remote and branch.<name>
.merge options will be used
after a:
--o--o--o--o` HEAD -> master
after b:
--o--o--o--o` HEAD -> master
o^ (origin/master, origin/HEAD)
after c:
(origin/master, origin/HEAD)
--o--o--o--o^--o` HEAD -> master
after d:
--o--o--o--o^--o` (HEAD -> master, origin/master)
