linux - 如何处理单引号之间双引号中有空格的变量

Question

这是我的:

#!/bin/sh
var="file1 is installed\n\n"
var=$var"file2 is installed" 

...

su $USER -c 'export DISPLAY=0:0;zenity --info --text="<span size=\"large\">pylink library has been installed.</span>\n\nFiles are installed to: $* --title="eyelink_core lib" --ok-label="Ok"' "$var"

but when I run it, I always get: file1 is installed\n\nfile2 is installed: -c: line 0 unexpected EOF while looking for matching '"'

谁知道怎么解决？谢谢!

\n 在双引号字符串中没有被特殊对待。请改用 ANSI 引号。

var=$'file1 is installed\n\n'

或者，简单地按字面意思嵌入换行符:

var="file1 is installed
