file directory permission

I have a directory /fs/hl/src/a/

Below is the command I use:
%ls -la src/
total 16
drwxr-xr-x 4 hl aaa 512 May 18 14:05 .
drwxr-xr-x 4 hl aaa 512 May 18 14:05 ..
drw-r--r-- 2 hl aaa 512 May 18 14:05 a
drw-r--r-- 2 hl aaa 512 May 18 14:06 b

%ls -la src/a/
ls: src/a/.: Permission denied
ls: src/a/..: Permission denied
ls: src/a/a: Permission denied

%ls src/a/
ls: src/a/a: Permission denied

Why I cannot read file/directory in src/a since my src/ directory permission is open to read?

This cause me a problem when I try to use rsync command.. my master directory have same file permission as this and i can do "ls" at master directory but when i rsync the whole master directory to my own disk space.. I get permission denied.. ????

thanks,
hl

execuutable perms make the dir searchable. one thing that needs search perms is stat, which ls -l needs. A plain ls or ls -a will show the dir contents because you have read perms. So pkwan is correct, you do need x perms to see what the things in the dir are, or to see anything in the dirs subdirs.

Hi,

yes. Once I change to --x, I can do ls -la.

However, the strange is I get this file permission structure from a master copy directory. It have the same structure that without "x" perms. But i still can do ls -la at that master directory but not my own. I wonder why the master copy can do ls -la? Is there any tricks there?

This give problem in the half way of my rsync process. I cannot continue to rsync that particular directory stuff to my own diskspace. my diskspace will not allowed rsync to mkdir with error message "permission denied".

thanks,

I asume that you're user common when you do the ls -la on .../thailand, while you're another user when you do the rsync
