Hi Gurus ,
I hope you are doing great .
Other than owner of the file , OTHERS and GROUP should be restricted from read or write a file created by the owner.
OTHERS and GROUP should be only allowed to execute the file.
Thanks in advance. (8 Replies)

acltotext
acltotext(3SEC) File Access Control Library Functions acltotext(3SEC) NAME
acltotext, aclfromtext - convert internal representation to or from external representation SYNOPSIS
cc [ flag... ] file... -lsec [ library... ] #include <sys/acl.h> char *acltotext(aclent_t *aclbufp, int aclcnt); aclent_t *aclfromtext(char *acltextp, int *aclcnt); DESCRIPTION
The acltotext() function converts an internal ACL representation pointed to by aclbufp into an external ACL representation. The space for the external text string is obtained using malloc(3C). The caller is responsible for freeing the space upon completion.. The aclfromtext() function converts an external ACL representation pointed to by acltextp into an internal ACL representation. The space for the list of ACL entries is obtained using malloc(3C). The caller is responsible for freeing the space upon completion. The aclcnt argu- ment indicates the number of ACL entries found. An external ACL representation is defined as follows: <acl_entry>[,<acl_entry>]... Each <acl_entry> contains one ACL entry. The external representation of an ACL entry contains two or three colon-separated fields. The first field contains the ACL entry tag type. The entry type keywords are defined as: user This ACL entry with no UID specified in the ACL entry ID field specifies the access granted to the owner of the object. Otherwise, this ACL entry specifies the access granted to a specific user-name or user-id number. group This ACL entry with no GID specified in the ACL entry ID field specifies the access granted to the owning group of the object. Otherwise, this ACL entry specifies the access granted to a specific group-name or group-id number. other This ACL entry specifies the access granted to any user or group that does not match any other ACL entry. mask This ACL entry specifies the maximum access granted to user or group entries. default:user This ACL entry with no uid specified in the ACL entry ID field specifies the default access granted to the owner of the object. Otherwise, this ACL entry specifies the default access granted to a specific user-name or user-ID number. default:group This ACL entry with no gid specified in the ACL entry ID field specifies the default access granted to the owning group of the object. Otherwise, this ACL entry specifies the default access granted to a specific group-name or group-ID number. default:other This ACL entry specifies the default access for other entry. default:mask This ACL entry specifies the default access for mask entry. The second field contains the ACL entry ID, as follows: uid This field specifies a user-name, or user-ID if there is no user-name associated with the user-ID number. gid This field specifies a group-name, or group-ID if there is no group-name associated with the group-ID number. empty This field is used by the user and group ACL entry types. The third field contains the following symbolic discretionary access permissions: r read permission w write permission x execute/search permission - no access RETURN VALUES
Upon successful completion, the acltotext() function returns a pointer to a text string. Otherwise, it returns NULL. Upon successful completion, the aclfromtext() function returns a pointer to a list of ACL entries. Otherwise, it returns NULL. ATTRIBUTES
