VOP_GETACL(9) BSD Kernel Developer's Manual VOP_GETACL(9)NAME
VOP_GETACL -- retrieve access control list for a vnode
SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
#include <sys/acl.h>
int
VOP_GETACL(struct vnode *vp, acl_type_t type, struct acl *aclp, struct ucred *cred, struct thread *td);
DESCRIPTION
This vnode call may be used to retrieve the access control list (ACL) from a file or directory.
Its arguments are:
vp The vnode of the file or directory.
type The type of ACL to retrieve.
aclp A pointer to an ACL structure to receive the ACL data.
cred The user credentials to use in authorizing the request.
td The thread requesting the ACL.
The cred pointer may be NULL to indicate that access control checks are not to be performed, if possible. This cred setting might be used to
allow the kernel to authorize ACL retrieval that the active process might not be permitted to do.
The vnode ACL interface defines the syntax, and not semantics, of file and directory ACL interfaces. More information about ACL management
in kernel may be found in acl(9).
LOCKS
The vnode will be locked on entry and should remain locked on return.
RETURN VALUES
If the aclp pointer will point to a valid ACL, then zero is returned. Otherwise, an appropriate error code is returned.
ERRORS
[EINVAL] The ACL type passed is invalid for this vnode.
[EACCES] The the caller does not have the appropriate privilege.
[ENOMEM] Sufficient memory is not available to fulfill the request.
[EOPNOTSUPP] The file system does not support VOP_GETACL().

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.
One thing I searched for was this:

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).

This is purely a fun project to see if it is possible in PURE... (3 Replies)
