Firstly, make sure that you have the necessary permissions to change the file permissions. This can be done by using chown command, or a sudo command in front of the chmod command. Once you have the permissions to change the file permissions, you can use the chmod command to change the default file permissions for a single file:
chmod <PERMISSIONS> <FILENAME> Or you can use the chmod command to assign certain permissions to all files in the current directory with this command:
chmod <PERMISSIONS>
* Where <PERMISSIONS> is the type of permissions to be set (e.g. 777 for full access) and <FILENAME> is the name of the file.
