这里echo到底是那里用得不对啊?

Question

我在脚本里面先定义一个set command1 "echo "CHECKING DISK USAGE" >>/tmp/1.log"
然后send "$command1\r";
为何报错extra characters after close-quote
    while executing
"set command1 "echo "
    (file "./1.sh" line 4)

这里echo到底是那里用得不对啊

Answer 1

我把"echo "CHECKING DISK USAGE" >>/tmp/1.log" 换成了 "echo ‘CHECKING DISK USAGE’ >>/tmp/1.log" 测试通过

Answer 2

shell读成了“echo” 和 " >>/tmp/1.log"
