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.
