awk - 如何在awk中手动设置记录分隔符？

Question

我有一个像下面这样的文件 -

vipin kumar ........................ kumar ......bangalore
    something something .......
;
vipin kumar ........................ kumar ......bangalore
    something something .......(testing
)
;
vipin kumar ......................... kumar .....bangalore
something something ;

我想要像下面这样的输出(文件中的名称和数字可以不同，但​​唯一的共同点是 - 当我们有“;”时，行就结束了)

vipin kumar ........................ kumar ......bangalore   something something .......;
vipin kumar ........................ kumar ......bangalore    something something .......(testing);
vipin kumar ......................... kumar .....bangaloresomething something ;

I want to set the RS to ";" . 

我尝试了以下命令 -

awk '{ORS=(NR%2==0?RS:FS)}1' file.txt

但它没有给出正确的输出，因为
NR%2 or NR%3 不起作用，因为我不确定在多少行后我会得到 ;
然后我尝试将 RS 设置为 ;下面使用

awk '{for(i=1;i<=NF;i++) (ORS=(if($i ~ /;/?RS:FS);break}1' file.txt

但是这个命令不起作用。

Answer 1

输入

$ cat f
vipin kumar ........................ kumar ......bangalore
    something something .......
;
vipin kumar ........................ kumar ......bangalore
    something something .......(testing
)
;
vipin kumar ......................... kumar .....bangalore
something something ;

输出

$ awk 'ORS=/;/?RS:FS'  f
vipin kumar ........................ kumar ......bangalore     something something ....... ;
vipin kumar ........................ kumar ......bangalore     something something .......(testing ) ;
vipin kumar ......................... kumar .....bangalore something something ;
