I am trying to write a program that gets file permission. I understand linux has ls -l can view file permission, but it has too many information that I have to process those strings in my program. Is there an easier command just return me the permission digits like:

$ getperm /home/file
0440
$

Here is a couple of suggestions:

Code:

$ find /path/to/file -printf "%#m\n"
$ stat -c%a /path/to/file
