This is A sample script
03:59:33 up 2:59, 4 users, load average: 0.08, 0.17, 0.17
PID TTY TIME CMD
4163 pts/2 00:00:00 unlock
4177 pts/2 00:00:00 ps
/home/lee#
由此看出,此脚本无法阅读但是能正确无误的被解释! ^_^
那么,我可不可以看lock和unlock的源代码呢?试试看
/home/lee#cat /root/tools/lock
cat: /root/tools/lock: 权限不够
/home/lee#cat /root/tools/unlock
cat: /root/tools/unlock: 权限不够
/home/lee#
呵呵,神奇吧~~~~ ^^^O^^^,这样,我们就达到了我们的初衷!
