我如何可以追加在bash

Question

兩個文件我有一個類似如下的文件：

File 1 
------ 
Field A, Field B, Field C 
1,2,3 

aa,bb,cc 

File 2 
------ 
Field D, Field E, Field F 
4,5,6 

dd,ee,ff 

I want to join them so the file looks like the following: 

Joined File 
----------- 
Field A, Field B, Field C, Field D, Field E, Field F 
1,2,3,4,5,6 

aa,bb,cc,dd,ee,ff 

所以它應該只是跳過空白行並追加其他一切行用逗號它作序。我這樣做，所以我可以在CSV文件中生成「列」並維護標題。空白行將始終匹配，所以我不需要邏輯來檢查該方面。

Answer 1

此： paste -d, "file 1" "file 2" | sed -e 's/^,$//g;s/^,/,,,/g'

會給：

 
Field A, Field B, Field C,Field D, Field E, Field F 
1,2,3,4,5,6 

aa,bb,cc,dd,ee,ff 
,,,o1,o2,o3 

此： paste -d, "file 1" "file 2" | sed -e 's/^,/,,,/g;s/,$/,,,/g'

會給：

 
Field A, Field B, Field C,Field D, Field E, Field F 
1,2,3,4,5,6 
,,,,, 
aa,bb,cc,dd,ee,ff 
,,,o1,o2,o3 

此： paste -d, "file 1" "file 2" | sed 's/^,$//g'

會給：

 
Field A, Field B, Field C,Field D, Field E, Field F
