Is There Any Way to Guess/Brute Force File System Hierarchy ?

I wonder if there is a way to guess or brute force file names inside a directory that we don't have permission to list what inside it.

I'll explain. we all know that the execution permission of a directory means that (group or other) can traverse this directory to read files inside this directory (the files should have read permission) if he knows the file names.

for exemple :

ls -ld dir1

drwx--x--x 2 root root 4.0K Aug 26 21:18 dir1

sudo ls -lA cs/

-rw-r--r--. 1 root root 0 Aug 26 21:17 f0

-rw-r--r--. 1 root root 0 Aug 26 21:17 f1

-rw-r--r--. 1 root root 0 Aug 26 21:17 f2

note that I used sudo to list files.

I tried to do :

stat dir1/{a..z}{0..9} 1>1.txt 2>/dev/null

cat 1.txt

inside 1.txt I found only stat of exist files, but what about 8, 9 10 characters names ?

any ideas ?

thanks in advance.
