消除"\"并连接两行为一行

battosai

如下:

1. $cat file
   
2. 12345  \
   
3. 6789
   
4. abcde \
   
5. fghi
   
6. dfjkldadfskdlfajsldkf
   
7. ABCDE \
   
8. FGHI
   
9. 98765 \
   
10. 4321

复制代码

想要的结果是

1. $cat file-end
   
2. 123456789
   
3. abcdefghi
   
4. dfjkldadfskdlfajsldkf
   
5. ABCDEFGHI
   
6. 987654321

复制代码

就是想把"\"去掉,然后和下一行合并为一行
我一点思路都没有,晕~~~~~

try it : ;)

2. cat file|tr -d ' '|while read i;do
3.         echo -n $i
4.         if echo $i|grep -v -q '\\';then
5.                 echo "\n"
6.         fi
7. done|tr -s '\n'

复制代码

测试结果:

[/home/javalee]cat file|tr -d ' '|while read i;do
=>echo -n $i
=>if echo $i|grep -v -q '\\';then echo "\n";fi;done|tr -s '\n'
123456789
abcdefghi
dfjkldadfskdlfajsldkf
ABCDEFGHI
