【GIT相关】解决终端命令行无效不存在的分支名称自动补全的问题

[dabing1022]

问题描述

远程分支已经将分支AAABBB删除，本地有个分支叫ABBB，当在终端中输入A，然后用Tab键自动补全的时候，老是把AAABBB给候选出来。很纳闷。远程分支AAABBB和本地分支AAABBB都已经被我删除，为什么还会补全提示呢？

例子

当前本地和所有的远程分支 以及 那些已经【死亡的无效的】分支

解决方法

git fetch --prune --all

prune英文单词为“剪枝”的意思，这个命令会将远程已经不存在的分支删除掉

一些僵尸分支已经被删除了，这下自动补全就不会再补全那些分支名称了 。
