2 Methods to Change Folder Permissions from Root to User in Linux
A folder has three types of owners – User, Group and Other; where the “root” user is a special type of User who enjoys administrative privileges. In addition, an owner has three permissions – read(r), write(w) and execute(w).
You can read our Comparative Analysis of Methods to distinguish between these two methods and best pick one for your need.
Method 01: Using the chown Command to Change Permissions from Root to User
The sole purpose of the chown command is to change ownership of a file or directory. For instance, my Ubuntu has a folder named “myfolder”. In this method, I will use the chown command to change the owner of “myfolder” from “root” to user “walid”.
Steps to Follow >
❶ At first, launch a Terminal in Ubuntu.
❷ (Optional) Copy the following command to view the current owner:
ls -ld ~/myfolder- ls: Lists content of a directory.
- -l: Shows detailed information.
- -d: Shows information only of the given directory.
- ~/myfolder: Path of the “myfolder” folder.
As you can see, both the current User and Group are root. Now I will change them to the user “walid”.
❸ Then insert the command below to change permission from root to user:
sudo chown –R walid:walid ~/myfolder- sudo: Grants root privileges.
- chown: Changes ownership.
- -R: Recursive Change; changes will be applied to all files and subdirectories within “myfolder”.
- walid:walid: New User and Group.
- ~/myfolder: Path of the “myfolder” folder.
❹ (Optional) Finally, to check the new owner, write the following command:
ls -ld ~/myfolder- ls: Lists content of a directory.
- -l: Shows detailed information.
- -d: Shows information only of the given directory.
- ~/myfolder: Path of “myfolder” folder.
Now both the User and the Group are “walid” instead of “root”.
Method 02: Using the chgrp Command to Change Permissions from Root to User
The chgrp command in Linux is used to change the Group ownership of a file or directory. In this method, I will use the chgrp command to change the Group ownership from “root” to “walid”. However, unlike the chown command, it isn’t possible to change the User using the chgrp command.
Steps to Follow >
❶ Firstly, open a Terminal in Ubuntu.
❷ (Optional) Insert the following command to view the current owner:
ls -ld ~/myfolder- ls: Lists content of a directory.
- -l: Shows detailed information.
- -d: Shows information only of the given directory.
- ~/myfolder: Path of “myfolder” folder.
Here both the User and Group are “root”. I will change the Group from “root” to user “walid”.
❸ Then use the following command to change folder permissions from root to user:
sudo chgrp -R walid ~/myfolder- sudo: Grants root privileges.
- chgrp: Changes the Group ownership of a file or directory.
- -R: Recursive Change; changes will be applied to all files and subdirectories within “myfolder”.
- walid: New Group owner of “myfolder” folder.
- ~/myfolder: Path of the “myfolder” folder.
❹ (Optional) Finally, to check the new owner, write the following command:
ls -ld ~/myfolder- ls: Lists content of a directory.
- -l: Shows detailed information.
- -d: Shows information only of the given directory.
- ~/myfolder: Path of “myfolder” folder.
Here you can see, the User hasn’t changed. However, the Group is “walid” instead of “root”.

Here I have provided some additional information related to the main topic of this article.
What are Ownership and Permission in Linux?
In general, there are three types of file permissions that are set for three categories of owners in Linux. The permissions are represented by a 10-character string, with the first character representing the file type (– for normal files & d for directory). Check the following sections where I will explain in detail.
Ownership in Linux
Linux has the following three types of owner:
- User: Represents the creator or main owner of the file. The owner has full control over the file and can modify its permissions.
- Group: A collection of users who share a common set of permissions. When a file is created, it is assigned to a specific group & all users who are members of that group, are granted the same permissions on the file.
- Other: Refers to all users who are not the owner of the file, also who do not belong to the group that the file belongs to. Other users are granted permissions separately from the owner and group.
Types of Permissions
A file or directory in Linux has the following three types of permissions:
- Read (r): Allows a user to view the contents of a file or lists of a directory, but cannot modify them.
- Write (w): Allows a user to modify the contents of a file or to create, delete, or rename files in a directory. For example, a user with only written permission on a file can modify its contents but can’t view or execute it.
- Execute (x): Allows a user to run an executable file or change into a directory, but can not view or write onto it.

How to Give Write Permission to a Folder for a User in Linux
Giving write permission to a user of a folder allows him to create, modify and delete files. You can follow the steps shown here to provide write permission for a user.
Steps to Follow >
❶ At first launch a Terminal in Ubuntu.
❷ (Optional) Now insert the following command to view current permissions:
ls -ld ~/myfolder- ls: Lists content of a directory.
- -l: Shows detailed information.
- -d: Shows information only of the given directory.
- ~/myfolder: Path of “myfolder” folder.
As you can see, user “walid” has no permission whatsoever. Now I will give the user write permission.
❸ Then execute the command below to give the user write permission:
chmod u+w ~/myfolder- chmod: Changes permissions of a file or directory.
- u+w: Adding write permission to the User.
- ~/myfolder: Path of the “myfolder” directory.
❹ (Optional) Finally, copy the following command to print new permissions:
ls -ld ~/myfolder- ls: Lists the content of a directory.
- -l: Shows detailed information.
- -d: Shows information only of the given directory.
- ~/myfolder: Path of “myfolder” folder.
Now the user “walid” has write permission.
How to Give Full Permission to User in Ubuntu
Sometimes it may require giving full permission to a user of a file or directory. Follow the steps below to do that –
Steps to Follow >
❶ Press CTRL+ALT+T to launch an Ubuntu Terminal.
❷ (Optional) Now write the following command to view current permissions:
ls -ld ~/myfolder- ls: Lists content of a directory.
- -l: Shows detailed information.
- -d: Shows information only of the given directory.
- ~/myfolder: Path of “myfolder” folder.
None has any permission here. In the following step, I will provide the user with full access to the folder.
❸ Then copy the command below to give the user full permission:
chmod u+rwx ~/myfolder- chmod: Changes permissions of a file or directory.
- u+rwx: Adding read, write and execute permissions to the User.
- ~/myfolder: Path of the “myfolder” directory.
❹ (Optional) At the end, use the command below to view new permissions:
ls -ld ~/myfolder- ls: Lists content of a directory.
- -l: Shows detailed information.
- -d: Shows information only of the given directory.
- ~/myfolder: Path of “myfolder” folder.
In the above image, you can see that the user has full permission now.
How to Change Linux Permissions 777 Using the chmod Command
In 777, the three digits represent permissions for the three types of owners (User, Group, Other) in Linux. Moreover, number 7 means read (4), write (2) and execute (1) permissions. Thus, in short, 777 denotes full permissions for all. Now to give full permission to all, follow the steps below.
Steps to Follow >
❶ Firstly, open a Ubuntu Terminal.
❷ (Optional) Now use the following command to view current permissions:
ls -ld ~/myfolder- ls: Lists content of a directory.
- -l: Shows detailed information.
- -d: Shows information only of the given directory.
- ~/myfolder: Path of “myfolder” folder.
Here the dashes (“-”) indicate that none has any permission whatsoever. However, I will provide all full permission now.
❸ Then insert the command below to give full permission to all:
chmod 777 ~/myfolder- chmod: Changes permissions of a file or directory.
- 777: Read, write and execute permissions to all.
- ~/myfolder: Path of the “myfolder” directory.
❹ (Optional) At last, use the command below to view the new permissions of the folder:
ls -ld ~/myfolder- ls: Lists the content of a directory.
- -l: Shows detailed information.
- -d: Shows information only of the given directory.
- ~/myfolder: Path of “myfolder” folder.
It is showing “rwxrwxrwx”, so everyone has full permission now.
