How do you make a file executable in Ubuntu?

An executable file's user rights must be correctly specified in order for it to run.

To achieve this, take the following actions:

Start a terminal.

Navigate to the folder containing the executable file.

Enter the command as follows:

for any . bin file: sudo chmod +x filename.bin

for any .run file: sudo chmod +x filename.run

Enter the necessary password when prompted to do so.

Now the current user with root access can execute the file.
