是否可以在Git项目的所有分支中执行"grep搜索"? [英] Is it possible to perform a 'grep search' in all the branches of a Git project?

问题描述

是否可以在基于Git控件的项目的所有分支中运行git grep?还是有另一个命令要运行?

Is it possible to run git grep inside all the branches of a Git control sourced project? Or is there another command to run?

推荐答案

问题"如何在git历史?"建议:

 git grep <regexp> $(git rev-list --all)

它将搜索所有提交，其中应包括所有分支.

That searches through all the commits, which should include all the branches.

另一种形式是:

git rev-list --all | (
    while read revision; do
        git grep -F 'yourWord' $revision
    done
)

您可以在中找到更多示例这篇文章:

我在一个足够大的项目上尝试了上述操作，以至于git抱怨参数的大小，因此，如果遇到此问题，请执行以下操作:

I tried the above on one project large enough that git complained about the argument size, so if you run into this problem, do something like:

git rev-list --all | (while read rev; do git grep -e <regexp> $rev; done)

(请参见下面此答案的最后一部分中的替代方法)

(see an alternative in the last section of this answer, below)

如果需要，请不要忘记这些设置:

Don't forget those settings, if you want them:

# Allow Extended Regular Expressions
git config --global grep.extendRegexp true
# Always Include Line Numbers
git config --global grep.lineNumber true

此别名也可以提供帮助:

This alias can help too:

git config --global alias.g "grep --break --heading --line-number"

Note: chernjie suggested that git rev-list --all is an overkill.

更精致的命令可以是:

A more refined command can be:

git branch -a | tr -d \* | xargs git grep <regexp>

仅允许您搜索分支(包括远程分支)

Which will allow you to search only branches (including remote branches)

您甚至可以为其创建bash/zsh别名:

You can even create a bash/zsh alias for it:

alias grep_all="git branch -a | tr -d \* | xargs git grep"
grep_all <regexp>

Update August 2016: R.M. recommends in the comments

尝试git branch版本时，我得到了"fatal: bad flag '->' used after filename".该错误与HEAD别名表示法相关.

I got a "fatal: bad flag '->' used after filename" when trying the git branch version. The error was associated with a HEAD aliasing notation.

我通过在tr和xargs命令之间的管道中添加sed '/->/d'来解决它.

I solved it by adding a sed '/->/d' in the pipe, between the tr and the xargs commands.

 git branch -a | tr -d \* | sed '/->/d' | xargs git grep <regexp>

也就是说:

alias grep_all="git branch -a | tr -d \* | sed '/->/d' | xargs git grep"
grep_all <regexp>
