如何使用sed刪除空白的未加引號的行？

我正在尋找一個sed腳本，將改變如何使用sed刪除空白的未加引號的行？

;; DONE Badge

(defstruct stack-api/badge 
    "This type represents a badge on a Stack Exchange `stack-api/site'. 

Some badges, like Autobiographer, are held in common across all 
Stack Exchange sites. Others, like most tag badges, vary on a 
site by site basis.

sites, even if a badge exists on both sites." 

    (award-count nil :type integer) 
    (badge-id nil :type integer) ; refers to a badge 
    (badge-type nil :type (memq 'named 
           'tag-based)) 
    (description nil :type string) ; unchanged in unsafe filters 
    (link  nil :type string) ; unchanged in unsafe filters

    (rank  nil :type (memq 'gold 
           'silver 
           'bronze) 

    (user  nil :type shallow-user)) 

;; Badge:1 ends here

到

積分爲在同去消除所有的評論，但我可以用一個管道。我主要不知道如何測試掃描儀是否在一個字符串內。

目前還不清楚您是否可以在一行中獲得兩個雙引號。假設沒有，那麼：

sed -e '/"/,/"/{p;d;}' -e '/^ *$/d'

第一表達對含有雙引號線之間相匹配時，打印每條線和刪除它，然後讀取下一（跳過第二個表達式）。第二個表達式刪除空白行。

如果你在一行上獲得雙引號，那麼你需要：

sed -e '/".*"/{p;d;}' -e '/"/,/"/{p;d;}' -e '/^ *$/d'
