如果你不局限于使用git命令提示符，那么你总是可以运行git gui并使用Branch->Delete菜单项。选择所有你想删除的分支，让它撕裂。

保持“开发”，并删除所有其他在本地

    git branch | grep -v "develop" | xargs git branch -D 

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.

嗯，在最坏的情况下，你可以用:

git branch | grep '3\.2' | xargs git branch -D

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.

也许你会发现这很有用:

如果你想删除所有不是'master'， 'foo'和'bar'的分支

git branch -D `git branch | grep -vE 'master|foo|bar'`

Grep -v 'something'是一个带有反转的匹配器。
