ICACLS

ICACLS name /save aclfile [/T] [/C] [/L] [/Q]
stores the DACLs for the files and folders that match the name into aclfile for later use with /restore. Note that SACLs, owner, or integrity labels are not saved.

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

ICACLS name /setowner user [/T] [/C] [/L] [/Q]
changes the owner of all matching names. This option does not force a change of ownership; use the takeown.exe utility for that purpose.

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 form 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:
N - no access
F - full access
M - modify access
RX - read and execute access
R - read-only access
W - write-only access
D - delete access

a comma-separated list in parentheses of specific rights:

DE - 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
(I) - permission inherited from parent container

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.
