Answer 1

我问你是否强行打开了颜色，答案似乎是肯定的。

要修复，请找到您的~/.gitconfig并将颜色更改为更多：

[color]
        ui = auto

这不会强制彩色输出;如果输出进入管道，则着色被丢弃。

Answer 2

您的问题不是OSX或xargs

mycroft:msg sja$ git branch bug
mycroft:msg sja$ git branch
  bug
* master
mycroft:msg sja$ git branch | grep bug | xargs git branch -D
Deleted branch bug (was 32c55a4).
mycroft:msg sja$ git branch
* master
mycroft:msg sja

mycroft:msg sja$ git branch bug_xxx
mycroft:msg sja$ git branch | grep bug_xxx | xargs git branch -D
Deleted branch bug_xxx (was 32c55a4).
mycroft:msg sja$ git branch
* master
mycroft:msg sja$

Answer 3

您可以使用-o的{{1}}选项仅打印行的匹配部分。

grep

$ git branch | grep -Eo "bug_[0-9]+" | xargs git branch -D打印没有着色字符的分支名称。

我找到了更简单的解决方案。试试grep -Eo "bug_[0-9]+"选项。

--no-color

当给出来自＆＃39; git branch＆＃39;的输出时，xargs不能在Mac上工作。
