How to Fix “chmod: Operation not permitted”?
Below are the solutions to resolve the chmod: Operation not permitted problem in the Linux Operating System.
Solution 1: Use sudo to Gain Proper Permissions
When we encounter the “chmod: Operation not permitted” error, it typically means you do not have the required permissions to change the file or directory’s attributes. Using sudo allows you to execute commands with superuser privileges, thereby granting you the necessary permissions to modify the file.
Syntax:
sudo chmod [permissions] [filename]
Example:
sudo chmod 755 /tmp/gfg
Output:
Use sudo to Gain Proper Permissions
Solution 2: Change File Ownership
If you frequently need to modify the file, a more permanent solution is to change the ownership of the file to your user. This will allow you to manage the file without needing to use sudo for each operation. Use the chown command to change the owner of the file.
Syntax:
sudo chown [username]:[groupname] [filename]
Example:
sudo chown cybergeek:cybergeek /tmp/gfg
chmod 755 /tmp/gfg
Output:
Change File Ownership
