file命令查看debugerver和springboard结果都是data--------------
➜ desktop file /Users/sq/Desktop/SpringBoard
/Users/sq/Desktop/SpringBoard: data
➜ desktop file /Users/sq/Desktop/debugserver
/Users/sq/Desktop/debugserver: data
debugserver 路径：/Developer/usr/bin/debugserver
springboard 路径：/System/Library/CoreServices/SpringBoard.app/springboard
请问一下为什么会不是可执行文件
