How do I change permissions in Linux for a folder and its subfolders/files?

Question

Aryan Kumar · Answer

Sure, there are a few ways to change permissions in Linux for a folder and its subfolders/files. Here are two methods:
Method 1: Using the chmod command
The chmod command is a command-line tool that can be used to change the permissions of files and directories. To change the permissions of a folder and its subfolders/files, you can use the following syntax:
chmod andlt;permissions> andlt;directory_path>
For example, to change the permissions of the directory /home/user/my_directory to read, write, and execute for the owner, read and execute for the group, and no permissions for others, you would run the following command:
chmod 755 /home/user/my_directory
The andlt;permissions> parameter can be a combination of the following characters:
r: Read permissionw: Write permissionx: Execute permission
The andlt;directory_path> parameter is the path to the directory that you want to change the permissions for.
Method 2: Using the chown command
The chown command is a command-line tool that can be used to change the ownership of files and directories. To change the ownership of a folder and its subfolders/files, you can use the following syntax:
chown andlt;owner> andlt;group> andlt;directory_path>
For example, to change the ownership of the directory /home/user/my_directory to the user
user and the group group, you would run the following command:
chown user:group /home/user/my_directory
The andlt;owner> parameter is the name of the user that you want to give ownership of the directory to.
The andlt;group> parameter is the name of the group that you want to give ownership of the directory to.
Method 3: Using the sudo command
If you are not the owner of the directory, you can use the sudo command to change the permissions. To change the permissions of a directory and its subfolders/files using the
sudo command, you can use the following syntax:
sudo chmod andlt;permissions> andlt;directory_path>
For example, to change the permissions of the directory /home/user/my_directory to read, write, and execute for the owner, read and execute for the group, and no permissions for others, you would run the following command:
sudo chmod 755 /home/user/my_directory
The sudo command allows you to run commands as the root user, which has full permissions on the system.
