WARNING

Linux Permission Denied

The system denies a user or process access to a file, directory, or resource due to insufficient permissions.

Common Causes

  • Insufficient read, write, or execute permissions on the target file or directory.
  • Attempting to access a file owned by another user without appropriate group membership or sudo privileges.
  • Trying to execute a file that is not marked as executable or is a script with an incorrect interpreter (shebang) line.

How to Fix

1 Check and Modify Permissions

Use `ls -l` to view current permissions and `chmod` to grant the necessary read (r), write (w), or execute (x) permissions.

BASH
$ ls -l /path/to/file # Example: Add read and execute for user, read for group and others chmod 755 /path/to/file

2 Change File Ownership

If you are the root user or have sudo privileges, change the ownership of the file to your user or the appropriate group using `chown`.

BASH
$ sudo chown $USER:$USER /path/to/file

3 Use Sudo for Elevated Privileges

Prepend the command with `sudo` to execute it with superuser privileges, if the action requires it and you have sudo access.

BASH
$ sudo cat /etc/shadow
