permisssion

[Raj Har]

Hiiii all,
               i am little bit confused.

#mkdir /java
#chmod 754 /java
i can run "ls" command but i can not run "ls -l" command on /java directory
from  other user.

#mkdir /php
#chmod 756 /php
i can not create file in /php directory without execute permission but
without execute permission i can run "ls" command???

basically what happening when i am running "touch /java/h" without execute
permission?


any help??
thanks
