When using sudo to allow edits to files, I regularly get 'permission denied'.
For example, my mouse is jittery and sluggish, so I want to disable polling:
sudo echo "options drm_kms_helper poll=N">/etc/modprobe.d/local.conf
I'm prompted for a password, and then get:
bash: /etc/modprobe.d/local.conf: Permission denied
So I tried to do a temporary change to disable polling by using:
sudo echo N> /sys/module/drm_kms_helper/parameters/poll
Yet again the system responded with:
bash: /sys/module/drm_kms_helper/parameters/poll: Permission denied
Any ideas?

Output redirection (via the
>
operator) is done by the shell, not by echo. You have to login as rootThen you can use redirection
Otherwise you can run bash string with sudo
