ACL_CMP(3) BSD Library Functions Manual ACL_CMP(3)NAME
acl_cmp -- compare two ACLs
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include <sys/types.h>
#include <acl/libacl.h>
int
acl_cmp(acl_t acl1, acl_t acl2);
DESCRIPTION
The acl_cmp() function compares the ACLs pointed to by the arguments acl1 and acl2 for equality. The two ACLs are considered equal if for
each entry in acl1 there is an entry in acl2 with matching tag type, qualifier, and permissions, and vice versa.
RETURN VALUE
If successful, the acl_cmp() function returns 0 if the two ACLs acl1 and acl2 are equal, and 1 if they differ. Otherwise, the value -1 is
returned and the global variable errno is set to indicate the error.
ERRORS
If any of the following conditions occur, the acl_cmp() function returns -1 and sets errno to the corresponding value:
[EINVAL] The argument acl1 is not a valid pointer to an ACL.
The argument acl2 is not a valid pointer to an ACL.
STANDARDS
This is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 ("POSIX.1e", aban-
doned).

ACL_EQUIV_MODE(3) BSD Library Functions Manual ACL_EQUIV_MODE(3)NAME
acl_equiv_mode -- check for an equivalent ACL
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include <sys/types.h>
#include <acl/libacl.h>
int
acl_equiv_mode(acl_t acl, mode_t *mode_p);
DESCRIPTION
The acl_equiv_mode() function checks if the ACL pointed to by the argument acl contains only the required ACL entries of tag types
ACL_USER_OBJ, ACL_GROUP_OBJ, and ACL_OTHER, and contains no permissions other that ACL_READ, ACL_WRITE or ACL_EXECUTE. If the ACL has this
form, it can can be fully represented with the traditional file permission bits, and is considered equivalent with the traditional file per-
mission bits.
If acl is an equivalent ACL and the pointer mode_p is not NULL, the value pointed to by mode_p is set to the value that defines the same
owner, group and other permissions as contained in the ACL.
RETURN VALUE
On success, this function returns the value 0 if acl is an equivalent ACL, and the value 1 if acl is not an equivalent ACL. On error, the
value -1 is returned, and errno is set appropriately.
ERRORS
If any of the following conditions occur, the acl_equiv_mode() function returns the value -1 and sets errno to the corresponding value:
[EINVAL] The argument acl is not a valid pointer to an ACL.
STANDARDS
This is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 ("POSIX.1e", aban-
doned).

Hello,
I am trying to make a bash script that will analyze and document Cisco (router) ACLs that will output a file with the source, destination, protocol, and ports (ports of the destination only) into a text file.

Hi everybody
As the title says I wonder if the usual (in my case Ubuntu 14.04 LTS) linux installation root does in fact uses any of the ACLs possible extensions in any of its files/dirs
