ICACLS options at Windows 2008 server Core



Reset the NTFS Files/Folders Permissions at Windows using CACLS utility.


ICACLS name /save aclfile [/T] [/C] [/L] [/Q]
store the the acls for the all matching names into aclfile for
later use with /restore.

ICACLS directory [/substitute SidOld SidNew [...]] /restore aclfile
[/C] [/L] [/Q]
applies the stored acls to files in directory.

ICACLS name /setowner user [/T] [/C] [/L] [/Q]
changes the owner of all matching names.

ICACLS name /findsid Sid [/T] [/C] [/L] [/Q]
finds all matching names that contain an ACL
explicitly mentioning Sid.

ICACLS name /verify [/T] [/C] [/L] [/Q]
finds all files whose ACL is not in canonical for or whose
lengths are inconsistent with ACE counts.

ICACLS name /reset [/T] [/C] [/L] [/Q]
replaces acls with default inherited acls for all matching files

ICACLS name [/grant[:r] Sid:perm[...]]
[/deny Sid:perm [...]]
[/remove[:g|:d]] Sid[...]] [/T] [/C] [/L] [/Q]
[/setintegritylevel Level:policy[...]]

/grant[:r] Sid:perm grants the specified user access rights. With :r,
the permissions replace any previouly granted explicit permissions.
Without :r, the permissions are added to any previously granted
explicit permissions.

/deny Sid:perm explicitly denies the specified user access rights.
An explicit deny ACE is added for the stated permissions and
the same permissions in any explicit grant are removed.

/remove[:[g|d]] Sid removes all occurrences of Sid in the acl. With
:g, it removes all occurrences of granted rights to that Sid. With
:d, it removes all occurrences of denied rights to that Sid.

/setintegritylevel [(CI)(OI)]Level explicitly adds an integrity
ACE to all matching files. The level is to be specified as one
of:

L[ow]
M[edium]
H[igh]

Inheritance options for the integrity ACE may precede the level
and are applied only to directories.

/inheritance:e|d|r

e - enables inheritance
d - disables inheritance and copy the ACEs
r - remove all inherited ACEs


Note:
Sids may be in either numerical or friendly name form. If a numerical
form is given, affix a * to the start of the SID.

/T indicates that this operation is performed on all matching
files/directories below the directories specified in the name.

/C indicates that this operation will continue on all file errors.
Error messages will still be displayed.

/L indicates that this operation is performed on a symbolic link
itself versus its target.

/Q indicates that icacls should supress success messages.

ICACLS preserves the canonical ordering of ACE entries:

Explicit denials
Explicit grants
Inherited denials
Inherited grants


perm is a permission mask and can be specified in one of two forms:
a sequence of simple rights:

F - full access
M - modify access
RX - read and execute access
R - read-only access
W - write-only access

a comma-separated list in parenthesis of specific rights:

D - delete
RC - read control
WDAC - write DAC
WO - write owner
S - synchronize
AS - access system security
MA - maximum allowed
GR - generic read
GW - generic write
GE - generic execute
GA - generic all
RD - read data/list directory
WD - write data/add file
AD - append data/add subdirectory
REA - read extended attributes
WEA - write extended attributes
X - execute/traverse
DC - delete child
RA - read attributes
WA - write attributes

inheritance rights may precede either form and are applied
only to directories:

(OI) - object inherit
(CI) - container inherit
(IO) - inherit only
(NP) - don't propagate inherit


Examples:

icacls c:\windows\* /save AclFile /T
- Will save the ACLs for all files under c:\windows
and its subdirectories to AclFile.

icacls c:\windows\ /restore AclFile
- Will restore the Acls for every file within
AclFile that exists in c:\windows and its subdirectories

icacls file /grant Administrator:(D,WDAC)
- Will grant the user Administrator Delete and Write DAC
permissions to file

icacls file /grant *S-1-1-0:(D,WDAC)
- Will grant the user defined by sid S-1-1-0 Delete and
Write DAC permissions to file
