Hi,
I'm writing a post-upgrade script and I want to find which files don't have read and execute to everyone.
I can run a find . ! -perm, but then I have to use a list of the possible permissions (777,775, 755 etc). Is there a more elegant solution?
Thanks (2 Replies)

vfs_preopen
VFS_PREOPEN(8) System Administration tools VFS_PREOPEN(8)NAME
vfs_preopen - Hide read latencies for applications reading numbered files
SYNOPSIS
vfs objects = preopen
DESCRIPTION
This VFS module is part of the samba(7) suite.
This module assists applications that want to read numbered files in sequence with very strict latency requirements. One area where this
happens in video streaming applications that want to read one file per frame.
When you use this module, a number of helper processes is started that speculatively open files and read a number of bytes to prime the
file system cache, so that later on when the real application's request comes along, no disk access is necessary.
This module is stackable.
OPTIONS
preopen:names = /pattern/
preopen:names specifies the file name pattern which should trigger the preopen helpers to do their work. We assume that the files are
numbered incrementally. So if your file names are numbered FRAME00000.frm FRAME00001.frm and so on you would list them as
preopen:names=/FRAME*.frm/
preopen:num_bytes = BYTES
Specifies the number of bytes the helpers should speculatively read, defaults to 1.
preopen:helpers = NUM-PROCS
Number of forked helper processes, defaults to 1.
preopen:queuelen = NUM-FILES
Number of files that should be speculatively opened. Defaults to the 10 subsequent files.
VERSION
This man page is correct for version 3.3 of the Samba suite.
