Question

替換文本，我有以下腳本我使用刪除混帳合併分支：

function Remove-MergedBranches 
{ 
    git branch -a --merged | 
    ForEach-Object { $_.Trim() } | 
    Where-Object {$_ -NotMatch "^\*"} | 
    Where-Object {-not ($_ -Like "*master")} | 
    Where-Object {-not ($_ -Like "*develop")} | 
    Where-Object {-not ($_ -Like "*dev")} | 
    % {$_.replace("/remotes","")} | 
    ForEach-Object { git branch -d $_ } 
} 

的replace不工作。

一個分支可能是remotes/origin/tg-training-section

Answer 1

您wan't更換/remotes在remotes/origin/tg-training-section不匹配（它不以斜線開始），所以你可能想省略斜線：

# .... 
% {$_.replace("remotes","")} 

另一種方式是通過使用-replace用正則表達式替換/remotes和remotes：

# .... 
% {$_ -replace '\/?remotes'} 

我還會考慮甚至使用\b\/?remotes以確保您不會替換字符串中的remotes。
