在bash中转义变量

Question

I have a text file with a lot of lines like messages:

1. valid user
2. operation enable
3. you don\\'t have rights to do this
4. please enter more than 5 characters ...

and i use a bash script to read this file like

while read line
do
    ....
    echo "${line}"
    ....
done

and returns all good, but in the message 3, just return:

1. you don't have rights to do this

without the "\\"

how i can return the exactly line?

Answer 1

然后尝试read -r line 。
