| filename | Displays ACLs. |
| /T | Changes ACLs of specified files in the current directory and all subdirectories. |
| /E | Edit ACL instead of replacing it. |
| /C | Continue on access denied errors. |
| /G user:perm | Grant specified user access rights.
| Perm can be: R | Read |
| W | Write |
| C | Change (write) |
| F | Full control |
|
| /R user | Revoke specified user's access rights (only valid with /E). |
| /P user:perm | Replace specified user's access rights.

R | Read |

Wildcards can be used to specify more that one file in a command. You can specify more than one user in a command. Examples cacls myfile.txt Displays the ACLs for the myfile.txt file. Below is an example of what this may look like.
| C:\WINNT\MYFILE.TXT | BUILTIN\Users:R
BUILTIN\Power Users:C
BUILTIN\Administrators:F
NT AUTHORITY\SYSTEM:F |
cacls myfile.txt /e /g mrhope:f Grants the user "mrhope" full rights to the myfile.txt file. If user was to look at the ACLs again using the above command, they would now see that the mrhope user is in the list. |
