sed 循环读入 删除回车

specialco

RT ，网上有人大虾写的命令是：sed ':a;N;$!ba;s/\n/ /g' test， 不过好像测试没用，求指点，怎么做循环

看不出有什么区别。。。

如果只是把全部变成一行：
tr -d "[\n]" <ufile

1. huang@huang:~$ cat test
   
2. Prctnr Cnum Id,Asgnmt Id,Strt Dt,End Dt,Cre T,Asgnmt Catgry Cd,Project Name,Client Name,Rem Stat Txt

4. ICBC PF PCR
   
5. OS fulfilled and closed"

8. huang@huang:~$ tr -d "[\n]" <test

原来的行数：
1.  Prctnr Cnum Id,Asgnmt Id,Strt Dt,End Dt,Cre T,Asgnmt Catgry Cd,Project Name,Client Name,Rem Stat Txt
2.060069672,"10,846,782.",11/14/13,12/13/13,11/13/13 04:07 AM,BIL,"WM-FZUCP74, ICBC PF PCR",INDUSTRIAL AND COMMERCIAL BANK OF,"C.02420.004, WM-FZUCP74,ICBC 3.PF PCR

要转成：

是呀，很多命令网上都有，可是拿过来自己用的时候就不灵了。郁闷

就比如匹配末尾行号不是”的命令

sed '/[^"]$/s/./x/' filename 好像就替换不了
