我有一個檔案如下
"time":"2022-03-01T12:00:25.388Z","duration":0.8255,"error":0
"time":"2022-03-01T12:00:26.809Z","duration":0.29521,"error":0,"state":"pending
"time":"2022-03-01T12:00:29.053Z","duration":2.90688,"error":0,"options":"merge_request.create
"time":"2022-03-01T12:00:00.635Z","duration":0.46049,"error":0
"time":"2022-03-01T12:00:39.351Z","duration":0.76487,"error":0,"state":"failed
我想在末尾添加 " 但只添加到以字串結尾的行
我給了sed -i 's/$/",/' filename，但它在所有行的末尾添加了引號。
所需的輸出是
"time":"2022-03-01T12:00:25.388Z","duration":0.8255,"error":0
"time":"2022-03-01T12:00:26.809Z","duration":0.29521,"error":0,"state":"pending"
"time":"2022-301T12:00:29.053Z","duration":2.90688,"error":0,"push_options":"merge_request.create"
"time":"2022-03-01T12:00:00.635Z","duration":0.46049,"error":0
"time":"2022-03-01T12:00:39.351Z","duration":0.76487,"error":0,"state":"failed"
有沒有辦法做到這一點？
uj5u.com熱心網友回復：
您可以使用
sed 's/:"[^"]*$/&"/' file > tmp && mv tmp file
sed -i 's/:"[^"]*$/&"/' file # GNU sed
's/:"[^"]*$/&"/'命令的意思是：
:"[^"]*$- 匹配一個:"子字串，然后匹配零個或多個字符，"直到字串結尾&""- 用它自己和一個字符替換匹配。
查看在線演示：

提出awk解決方案：
awk '/[[:alpha:]]$/{$0=$0"\""}1' input.txt

使用sed
$ sed 's/[a-z]$/&"/' input_file
