创建分支repo sync拉取分支后repo branch和所有仓库下面执行git branch 都显示“no branches”这是正常的。.repo/manifests/default.xml中revision定义的版本进行更新的我们默认定义的是master它是按master对应的revision更新的无branch后续必须执行repo start 分支名 --all 建分支才能开发。基于当前分支创建新分支$ .repo/repo/repo forall -c git checkout -b ota-debuggit 常用命令download gitgit命令参数add clone fetch-pack ls-files notes remote-http stash add--interactive column filter-branch ls-remote p4 remote-https status am commit fmt-merge-msg ls-tree pack-objects remote-testsvn stripspace annotate commit-tree for-each-ref mailinfo pack-redundant repack submodule apply config format-patch mailsplit pack-refs replace subtree archive count-objects fsck merge patch-id request-pull symbolic-ref bisect credential fsck-objects merge-base prune rerere tag bisect--helper credential-cache gc merge-file prune-packed reset unpack-file blame credential-cache--daemon get-tar-commit-id merge-index pull rev-list unpack-objects branch credential-store grep merge-octopus push rev-parse update-index bundle daemon hash-object merge-one-file quiltimport revert update-ref cat-file describe help merge-ours read-tree rm update-server-info check-attr diff http-backend merge-recursive rebase send-pack upload-archive check-ignore diff-files http-fetch merge-resolve receive-pack sh-i18n--envsubst upload-pack check-mailmap diff-index http-push merge-subtree reflog shell var check-ref-format diff-tree imap-send merge-tree relink shortlog verify-pack checkout difftool index-pack mergetool remote show verify-tag checkout-index difftool--helper init mktag remote-ext show-branch web--browse cherry fast-export init-db mktree remote-fd show-index whatchanged cherry-pick fast-import instaweb mv remote-ftp show-ref write-tree clean fetch log name-rev remote-ftps stageThe most commonly used git commands are: add Add file contents to the index bisect Find by binary search the change that introduced a bug branch List, create, or delete branches checkout Checkout a branch or paths to the working tree clone Clone a repository into a new directory commit Record changes to the repository diff Show changes between commits, commit and working tree, etc fetch Download objects and refs from another repository grep Print lines matching a pattern init Create an empty Git repository or reinitialize an existing one log Show commit logs merge Join two or more development histories together mv Move or rename a file, a directory, or a symlink pull Fetch from and integrate with another repository or a local branch push Update remote refs along with associated objects rebase Forward-port local commits to the updated upstream head reset Reset current HEAD to the specified state rm Remove files from the working tree and from the index show Show various types of objects status Show the working tree status tag Create, list, delete or verify a tag object signed with GPGgit代码审核配置可以使用下面的配置来关闭代码检查:git config core.autocrlf truegit config core.safecrlf true还可以在提交代码时禁止代码检查git commit --no-verify-a或者可以这样做git config core.whitespace “trailing-space,space-before-tab”git config apply.whitespace “trailing-space,space-before-tab”还有另外一个办法就是在pre-commit添加如下语句if(/\s$/){#bad_line(“trailing whitespace”, $_);}git 强制回退到某提交退回到某一提交要慎用会删掉退回处之前的所有提交git reset --hard commit_idgit取消提交文件跟踪git rm --cached abc.txt #

拉取合并如果有远程仓库需要先同步合并git push # 推送到远程仓库如果有远程仓库git stash pop # 恢复隐藏忽略的文件这一步非常重要git status # 此时之前被隐藏的改动文件恢复显示。
