CHMOD(CHANGE MODE) is a popular command on Unix and similar operating systems that allows you to change the access mode of a file through permissions, attributes, and ownership of the file.
The chmod syntax on Linux looks like this:
chmod [reference][operator][mode] file...

Elevate the privileges of a program in Windows 10 with "Run as administrator".
If Linux users try to use Windows, they may need to CHMOD at some point and may be looking for a Windows equivalent of Linux's CHMOD. If you are also in this situation, Ourtechroom will help you to find Chmod in Windows.
💡 It should be noted that there is no specific CHMOD command in Windows, but alternative keywords likeATTRIBUTEyICCL. Since Linux (or Unix) and Windows are based on different security models, their permission-related attributes and commands also differ.
Let's talk about the Attrib command and icacls.
ICACLS command
WhaticaclsThe command, similar to chmod, gives you the ability to set granular permissions on files and folders.
They allow users to view and change an access control list (ACL) for files and folders.
An access control list, or ACL, is a list that users or groups can use to grant permissions to an object on an NTFS file system.
Its general syntax is as follows:
Now let's see how to change the access permission for files and folders using the ICACLS command.
1First create a folderDemoOrdnerand filedemofile.txt.
mkdir DemoOrdnerecho > file demo.txt
2Now we are going to create a read-only permission for these folders and files.
icacls.exe DemoOrdner/restablecer
icacls DemoFolder/Herencia:r
icacls DemoFolder /grant to "all":RIt is always better to reset the permission before assigning.
Here we only grant read permission to each user.

And if you try to delete the folder you get theFolder access deniedError as below.
You can also do the following for the files:
icacls.exe DemoFile.txt /reset
icaclsDemoDatei.txt/Erbe:r
icaclsDemoDatei.txt/conceder "all":Rhere
/reset to defaultresets the previously set permission.
/Erbe:rindicates removal of all legacy ACEs.
/grant- Adds a new ACE to the ACL that grants read-only access to the special identity Everyone.
If you want to recursively access all subfolders and subfiles, you can add "/t" as shown below:
icacls DemoFolder /grant to "all":R /tIf you get an error message and want to ignore it, add "/c" as shown below:
icacls DemoFolder /otorgar a "todos":r /t /c
Here DemoFolder is already an existing folder and if there is a subfolder in this folder then it works, but if you want to apply this permission to all future created subfolders and files, you need to do the following:
icacls DemoFolder /grant:r Todos:(HOLA)(A)W / t/grantConrsupersedes any explicit permission previously granted. When:rnot specified in/grant, the permissions are added to any previously granted explicit permissions.
Grant read access to currently logged in users.
$ruta = "DemoDatei.txt";
icacls.exe $route /GRANT:R "$($env:USERNAME):(R)"
This allows only currently logged in users to read only the DemoFile.txt file
Grant FullControl access to groups of users
$path = "DemoDatei.txt";
icacls $route /grant user:F
WhereFgrants full access to the file or folder.

$path = "DemoDatei.txt";
icacls $route /concede Benutzer:M
WoMETROmeans modify
set multiple permissions
If you want to set different permissions, you can do the following:
icacls DemoFolder /grant:r Todos:RW
This way we can set multiple permissions on the folder or file here for each user. In my case, I used the "Everyone" user and set the "Read and Write" permission for the "DemoFolder" folder.
Remove all access from Everyone
Remove all access for everyone to the DemoFolder.
icacls-Demoordner /herencia:d /t /c
demo folder icacls /remove:g All /t /cfirst command: Removes object inheritance.
second command: remove a user or group from ACLs on an object
GUI equivalent of the iCACLS command
We can use GUI with the following command.
1Right click on the folder/file you want to set permissions on as CHMOD
2AndsecurityTab
3Click the Edit button
4Then on the next screen select the desired group and username and then onpermissions for everyone, check the box in the first column if you want to grant access using the key described in the row, and if you want to deny access, check the box in the second column.
In my case I removed all the permissions of the Administrators user (DIWAS\Administrators).
ATTRIB command
ATTRIB provides the basic functionality of the CHMOD attribute. The main function of this command is to remove and set file attributes (read-only, hidden, system, and archive) and thus allows users to view, set, or remove the file attributes of read-only, hidden, and archive files. a file or assigned to a folder. attrib.exe is solely responsible for changing the file's attributes; it does not affect file permissions in any way.
Also read:How to list all environment variables?
Let's see some of the examples:
Change the read-only attribute to file or folder
attrib +r Date name.txt
Provide hidden attribute for file or folder
attrib +h Datename.txt
Clear all file or folder attributes
attrib -s -h -r Datename.txt
The minus sign is used to clear all attributes, such as read-only, hidden, and archived file attributes, for the file and folder.
Note that attrib has the following attributes:
| +s | Use it when you want to set a file or folder as a system file |
| -s | Use it when you want to remove a file or folder as a system file |
| +h | Use it when you want to make a file or folder invisible. |
| -h | Use it when you want to show a hidden file or folder |
| +r | Use it when you want to make a file or folder read-only |
| -r | Use it when you want to remove the read-only ownership of the file or folder. |
Conclusion:
In this way we have successfully used the Windows command equivalent to CHMOD.
Frequently asked questions:
How to use CHMOD 400 in Windows Command?
You can use the help of the icacls command. You can try the following command line by line.
icacls.exe DemoFile.txt /reset
icacls.exe DemoFile.txt /grant:r "$($env:username):(r)"
icacls.exe DemoFile.txt /herencia:r
