如何按特定列排序格式？

Question

我有這樣的格式：

user: "some_text" 

我需要按字母順序排序由user。問題的文件是當用戶重複，我需要保持"some_text"的位置。 例如：

Jack: "Daniel has an apple" 
Daniel: "No" 
Daniel: "Jack is a morun" 
Daniel: "Alfa and beta" 
John: "Blah blah blah" 

我試圖sort -t':' -k1,1和我得到這個：

Daniel: "Alfa and beta" 
Daniel: "Jack is a morun" 
Daniel: "No" 
Jack: "Daniel has an apple" 
John: "Blah blah blah" 

我需要：

Daniel: "No" 
Daniel: "Jack is a morun" 
Daniel: "Alfa and beta" 
Jack: "Daniel has an apple" 
John: "Blah blah blah"

看看GNU排序的選項：

-s：穩定吸附劑牛逼通過禁用最後手段比較

sort -s -t':' -k1,1 file 

輸出：

 
Daniel: "No" 
Daniel: "Jack is a morun" 
Daniel: "Alfa and beta" 
Jack: "Daniel has an apple" 
John: "Blah blah blah"
