File permissions on Windows 10
Jan 21, · I'd like to change NTFS file system permissions and ownership using Powershell, both at the command line and from a Powershell script. I come from the Unix world, where it's pretty straightforward: To change ownership, you use the 'chown' command, and to change permissions, you use either 'chmod' or 'setfacl'.
Unix -like operating systems, such as Linux, running on shared high-performance computers use settings called permissions to determine who can access and modify the files and directories stored in their file systems.
Each file and directory in a file system is assigned "owner" and "group" attributes. Most commonly, by default, the user who creates a file or directory is set as owner of that file or directory. When needed for example, when a member of your research team leaves , the system's root administrator can change the user attribute for files and directories. To view the permissions for all files in a directory, use the ls command with the -la options. Add other options as desired; for help, see List the files in a directory in Unix.
In the output example above, the first character in each line indicates whether the listed object is a file or a directory. Directories are indicated by a d ; the absence of a d at the beginning of the first line indicates that myfile. Note the multiple instances of r , w , and x. These are grouped into three sets that represent different levels of ownership:.
In the example -rw-r--r-- , the owner permissions are rw- , indicating that the owner can read and write to the file but can't execute it as a program. In the example drwxr-xr-x , the owner permissions are rwx , indicating that the owner can view, modify, and enter the directory. To change file and directory permissions, use the command chmod change mode.
There are two basic ways of using chmod to change file permissions: The symbolic method and the absolute form. The first and probably easiest way is the relative or symbolic method, which lets you specify permissions with single letter abbreviations.
A chmod command using this method consists of at least three parts from the following lists:. For example, to add permission for everyone to read a file in the current directory named myfile , at the Unix prompt, enter:. If you omit the access class, it's assumed to be all, so you could also enter the previous example as:. You can also specify multiple classes and types with a single command. For example, to remove read and write permission for group and other users leaving only yourself with read and write permission on a file named myfile , you would enter:.
You can also specify that different permissions be added and removed in the same command. For example, to remove write permission and add execute for all users on myfile , you would enter:.
In each of these examples, the access types that aren't specified are unchanged. The previous command, for example, doesn't change any existing settings specifying whether users besides yourself may have read r access to myfile. The chmod command also operates on directories. For example, to remove write permission for other users on a subdirectory named mydir , you would enter:. To change permissions recursively in all subdirectories below the specified directory, add the -R option; for example, to grant execution permissions for other users to a directory mydir and all the subdirectories it contains, you would enter:.
Be careful when setting the permissions of directories, particularly your home directory; you don't want to lock yourself out by removing your own access. Also, you must have execute permission on a directory to switch cd to it. The other way to use the chmod command is the absolute form, in which you specify a set of three numbers that together determine all the access classes and types. Rather than being able to change only particular attributes, you must specify the entire state of the file's permissions.
The three numbers are specified in the order: user or owner , group, and other. Each number is the sum of values that specify read, write, and execute access:. You can think of the three digit sequence as the sum of attributes you select from the following table:. Sum all the accesses you wish to permit. To share a file or directory that you own with someone, you can grant read and execute privileges for that user.
However, you must also set the same privileges on any parent directories above the item you're sharing; if you don't, the user can't look and change into cd all the parent directories above your file or directory. If you think of a file system as a physical place, then permissions work like keys that let you access different directories:.
Imagine the path as a physical space:. You might try to do it this way:. However, a user can't read or access a subdirectory unless the user also has x permissions to the parent directories. In other words, the above command gives out a key to your closet, but not to your room or apartment.
This will let others move cd to the scripts directory. Because the parent directories don't have r permissions, users will only be able to look ls within the scripts directory, keeping the rest of your file system private.

Back to top View file permissions To view the permissions for all files in a directory, use the ls command with the -la options. For example, if you enter: ls -lah You should see output similar to the following: -rw-r--r-- 1 user1 group1 62 Jan 15 myfile. The letters rwx represent different permission levels: Permission Files Directories r can read the file can ls the directory w can write the file can modify the directory's contents.
This assumes that everyone already has access to the directory where myfile is located and its parent directories; that is, you must set the directory permissions separately.
