Please forgive me, but I am not a Unix expert. I'm supporting SAP r/3 and we are trying to run an external command from SAP to read a file at the unix level.

I have an executable that had permissions set to 700. I changed this to 770 and added a user to the group in an attempt to allow that userds to run the file. Obviously this didnt work or I wouldnt be here.

Hi,
A simple and silly question on Unix.
I have a directory named "a" and I would like to grant permission to group name "text" to access, read and execute my directory.
Could anyone help me?
Thanks. (2 Replies)
In our file system, the SGID for a directory is set right now. Any new files created in this directory will automatically be assigned the same group from the parent directory.
Is there a way to inherit the file permission from the parent directory as well? The OS is Solaris 2.8.
Example:... (1 Reply)
I need to find all the files that have group Read or Write permission or files that have user write permission.
This is what I have so far:
find . -exec ls -l {} \; | awk '/-...rw..w./ {print $1 " " $3 " " $4 " " $9}'
It shows me all files where group read = true, group write = true... (5 Replies)

All:
I'm having a problem with sudo on Solaris 5.10 that is giving me fits (and BTW, I'm a Linux admin by trade...).
The issue is that I have a number of users (myself included) that cannot sudo to root to complete user admin tasks. Assuming the user is jdoe, and the group with the elevated... (3 Replies)

I have a directory with the following permissions:
drwxrws--x
when I remove the group id and add it again with g+s or chmod 2765 , it
displays the group ID in capital "S" instead of lowercase "s"
tried to find this out on Google, but... (2 Replies)

vfs_hooks
VFS_HOOKS(9) BSD Kernel Developer's Manual VFS_HOOKS(9)NAME
vfs_hooks, vfs_hooks_unmount -- VFS hooks interface
SYNOPSIS
#include <sys/param.h>
#include <sys/mount.h>
void
vfs_hooks_unmount(struct mount *mp);
DESCRIPTION
The VFS hooks interface provides a way for different kernel subsystems to attach custom functions to specific VFS operations. This enforces
code separation by keeping the VFS's core sources uncluttered and makes all subsystem functionality reside in a single place. As an example,
this interface is used by the NFS server code to automatically handle the exports list for each mount point.
Hooks are described by a struct vfs_hooks object, as seen below:
struct vfs_hooks {
int (*vh_unmount)(struct mount *);
};
For simplicity, each field is named after the VFS operation it refers to. The purpose of each member function, alongside some important
notes, is shown below:
vh_unmount(mp)
This hook is executed during the unmount process of a file system.
For more information about the purpose of each operation, see vfsops(9). Note that any of these fields may be a null pointer.
After the definition of a struct vfs_hooks object, the kernel has to add it to the vfs_hooks link set using the VFS_HOOKS_ATTACH(struct
vfs_hooks *) macro.
Please note that this interface is incomplete on purpose to keep it in its smallest possible size (i.e., do not provide a hook that is not
used). If you feel the need to hook a routine to a VFS operation that is not yet supported by this interface, just add it to the files
described in CODE REFERENCES.
FUNCTIONS
The following functions are provided to the VFS code to run the hooked functions:
vfs_hooks_unmount(mp)
Runs all hooks for the VFS unmount operation. Given that these operations shall not fail, it returns void.
CODE REFERENCES
The VFS hooks interface is implemented within the files sys/kern/vfs_hooks.c and sys/sys/mount.h.
SEE ALSO intro(9), vfs(9), vfsops(9)HISTORY
The VFS hooks interface appeared in NetBSD 4.0.
