I'm not very clear on what you're asking, but I think this is what you're after.
我不太清楚你在问什么，但我认为这就是你所追求的。
if you have file.txt, you can do this
如果你有file.txt，你可以这样做
var1=$(cat /path/to/file.txt)
var1 = $（cat /path/to/file.txt）
you can then manipulate it how you please.
然后你可以随心所欲地操纵它。

You can access the variable by $var1, i.e. echo "$var1"
您可以通过$ var1访问变量，即echo“$ var1”
