[英]Linux Shell scripting: Storing the output of a command line program
The following command returns 2 lines and those are the temperatures of my CPU's: 以下命令返回两行,它们是我的CPU的温度:
acpi -t
How would I go about storing those 2 lines in a variable in a bash script so I can work with them? 我该如何将这2行存储在bash脚本的变量中,以便可以使用它们?
你尝试过这个吗?
var=$(acpi -t)
