读串入一个变量，直到在BASH某个词

Question

我有一个程序，输出是这样的：

stuff=Some text with spaces and other $pecial characters stuff2=1 stuff3=0 

我想在一个变量来获取所有的字符串，直到stuff2 = 1，所以变量是：

stuff=Some text with spaces and other $special characters 

我已经试过这样：

for word in $output 
while [ $word != "stuff2=1" ] 
do 
    var+=" "$word 
done 
done 

，但我得到的是“东西=一些”过来，再次。

Answer 1

这个怎么样？

stuff='Some text with spaces and other $pecial characters stuff2=1 stuff3=0' 

var="" 
for word in $stuff 
do 
    if [ "$word" == "stuff2=1" ] 
    then 
    break 
    fi 
    if [ "$var" != "" ] 
    then 
    var="${var} " 
    fi 
    var="${var}${word}" 
done 
echo "$var" 

Answer 2

$ eval $(sed "s/=/='/;s/ [^ ]*=.*/'/") 

 
$ echo $stuff 
Some text with spaces and other $pecial characters 

Answer 3

你可以用简单的bash参数扩展实现这一点：

line='stuff=Some text with spaces and other $pecial characters stuff2=1 stuff3=0' 
truncated=${line% stuff2=1*} 
echo "$truncated" 

stuff=Some text with spaces and other $pecial characters 

这是至关重要的引用变量时，你需要 “解引用” 了。

Answer 4

可以在bash来完成自身

stuff=${stuff/stuff2=1*/}
