Shell 数组

1.一般我们写脚本传递参数都是通过$1~$n 去传递给脚本，那么怎么传递数组元素函数（贴一下我之前写过minicom 串口log的代码）：
+#start capture serial log
+#kvm and xen environment
+start_capture_serial_log()

+ set timeout -1
+ expect {
+ "*assword:" { send "123456\r"; exp_continue}
+ "*(yes/no)?" { send "yes\r"; exp_continue }
+ eof { exit [ lindex [wait] 3 ] }
+ }
+ EOF
