这对我来说是正确的:

git branch | xargs git branch -d

git branch | xargs git branch -D

删除所有本地分支

git branch -d branch1 branch2 branch3已经可以工作了，但是在git 2.31(2021年第一季度)中会更快。 以前，当删除许多分支和标记时，代码习惯一次引用一个。 还有另一个API可以用来删除多个裁判，当裁判被打包时，它会产生相当大的性能差异。

8198907795:删除标签或分支时使用delete_refs 致谢:以利亚·纽伦 署名:菲尔·霍德

'git tag -d'(man) accepts one or more tag refs to delete, but each deletion is done by calling delete_ref on each argv. This is very slow when removing from packed refs. Use delete_refs instead so all the removals can be done inside a single transaction with a single update. Do the same for 'git branch -d'(man). Since delete_refs performs all the packed-refs delete operations inside a single transaction, if any of the deletes fail then all them will be skipped. In practice, none of them should fail since we verify the hash of each one before calling delete_refs, but some network error or odd permissions problem could have different results after this change. Also, since the file-backed deletions are not performed in the same transaction, those could succeed even when the packed-refs transaction fails. After deleting branches, remove the branch config only if the branch ref was removed and was not subsequently added back in. A manual test deleting 24,000 tags took about 30 minutes using delete_ref. It takes about 5 seconds using delete_refs.

git branch  | cut -c3- | egrep "^3.2" | xargs git branch -D
  ^                ^                ^         ^ 
  |                |                |         |--- create arguments
  |                |                |              from standard input
  |                |                |
  |                |                |---your regexp 
  |                |

编辑:

一个更安全的版本(由Jakub narabbski和Jefromi建议)，因为git分支输出并不用于脚本:

git for-each-ref --format="%(refname:short)" refs/heads/3.2\* | xargs git branch -D

．.． 或者xargs-free:

git branch -D `git for-each-ref --format="%(refname:short)" refs/heads/3.2\*`

最近，我在寻找同样问题的解决方案，最后我找到了一个答案，它工作得很好:

打开终端，或等价的。 输入git分支| grep " pattern "预览分支 这将被删除。 输入git branch | grep " pattern " | xargs git branch -D

这个解决方案非常棒，如果你想要每个命令的完整解释以及它是如何工作的，可以在这里给出。

你可能会喜欢这个小物件…在最终删除所有选择之前，它会拉出列表并要求确认每个项目……

git branch -d `git for-each-ref --format="%(refname:short)" refs/heads/\* | while read -r line; do read -p "remove branch: $line (y/N)?" answer </dev/tty; case "$answer" in y|Y) echo "$line";; esac; done`

使用-D强制删除(像往常一样)。

为了可读性，这里是逐行分解的…

git branch -d `git for-each-ref --format="%(refname:short)" refs/heads/\* |
    while read -r line; do 
        read -p "remove branch: $line (y/N)?" answer </dev/tty;
        case "$answer" in y|Y) echo "$line";; 
        esac; 
    done`

下面是xargs方法……

git for-each-ref --format="%(refname:short)" refs/heads/\* |
while read -r line; do 
    read -p "remove branch: $line (y/N)?" answer </dev/tty;
    case "$answer" in 
        y|Y) echo "$line";; 
    esac; 
done | xargs git branch -D

最后，我喜欢把它放在。bashrc中

alias gitselect='git for-each-ref --format="%(refname:short)" refs/heads/\* | while read -r line; do read -p "select branch: $line (y/N)?" answer </dev/tty; case "$answer" in y|Y) echo "$line";; esac; done'

这样我就可以说

gitSelect | xargs git branch -D.

Powershell的解决方案:

如果你正在运行窗口，你可以使用PowerShell一次删除多个分支…

git branch -D ((git branch | Select-String -Pattern '^\s*3\.2\..*') | foreach{$_.ToString().Trim()})
//this will remove all branches starting with 3.2.

git branch -D ((git branch | Select-String -Pattern 'feature-*') | foreach{$_.ToString().Trim()})
// this will delete all branches that contains the word "feature-" as a substring.

您还可以使用Powershell的Select-String命令对模式匹配的工作方式进行微调。看一下powershell文档。
