sed "/company/ a\ Then suddenly it happed"报错

ximen168

$sed "/company/ a\ Then suddenly it happend" quote.txt
sed: 1: "/company/ a\ Then sudde ...": extra characters after \ at the end of a command
运行报错.
$sed '/company/' a\ "Then suddenly it happend" quote.txt
这个也同样报错


但是我
cat append.sed
#!/usr/bin/sed -f
/company/ a\
Then suddenly it happed
却运行正常的

waker

sed "/company/ a \
Then suddenly it happend" quote.txt

__lxmxn__

1. sed '/company/aThen suddenly it happend' quote.txt

复制代码

ximen168

$sed "/company/ a \
? Then suddenly it happend" quote.txt
sed: 1: "/company/ a
Then sudde ...": command a expects \ followed by text
运行报这个错

sed '/company/a Then suddenly it happend' quote.txt
sed: 1: "/company/a Then suddenl ...": command a expects \ followed by text
还是一样的错,不知道为什么的

waker

csh?

1. 
   
2. sed "/company/ a \\
   
3. Then suddenly it happend" quote.txt
   

复制代码

csh?


sed "/company/ a \\
Then suddenly it happend" quote.txt

是csh,谢谢你的帮助,什么要多加一个\呢

waker

因为csh中 \+换行符=普通换行符 不管它在不在''或""里面

这是在bash中成功运行的.
sed '/company/ i\
utter confusion follow.\
> ' quote.txt
utter confusion follow.
It was an evening of splendid music and company.



但是到了csh下,却要这样运行
sed "/company/ a\\
? utter confusion follow.\
? " quote.txt
It was an evening of splendid music and company.
utter confusion follow.

得到的结果也不一样,差别很大的
我有几个问题要问
1.bash中用单引号,csh中用双引号.
2.csh中要屏蔽\,所以用\\,bash中就不要这样用的
3.得到的结果也不一样的,一个添加在前面一个添加在后面
