I want to use this command:
ls -l some_file

in my shell script

But I want to then determine if the file has execute permission for the file owner.

How could i do that?
Is there a way to then after it did the command above, to select a certain value from it eg:
-rwSr-Sr-- 1 philip philip 126 2008-10-01 17:15 test.java

Could i select the 4th character?

CHMOD(1)						      General Commands Manual							  CHMOD(1)

NAME
chmod - change mode SYNOPSIS
chmod mode file ... DESCRIPTION
The mode of each named file is changed according to mode, which may be an octal number or a symbolic change to the existing mode. A mode is an octal number constructed from the OR of the following modes. 0400 read by owner 0200 write by owner 0100 execute (search in directory) by owner 0070 read, write, execute (search) by group 0007 read, write, execute (search) by others A symbolic mode has the form: [who] op permission The who part is a combination of the letters u (for user's permissions), g (group) and o (other). The letter a stands for ugo. If who is omitted, the default is a. Op can be + to add permission to the file's mode, - to take away permission, and = to assign permission absolutely (all other bits will be reset). Permission is any combination of the letters r (read), w (write), x (execute), a (append only), and l (exclusive access). Only the owner of a file or the group leader of its group may change the file's mode. SOURCE
