Dynamic MOTD update on login

I've found in Ubuntu manual: http://manpages.ubuntu.com/manpages/bio … otd.5.html that files in

/etc/update-motd.d/

are executed by pam_motd on login. I assume that the same pam_motd is used in Arch, but in my case the files in the update-motd.d are not executed. Any ideas why? How to execute shell scripts to generate MOTD on each login?

Re: Dynamic MOTD update on login

I've seen it. It basically says that pam_motd is only capable of displaying files - not executing scripts. So, is ubuntu using different pam_motd, or what is happening here?

Turns out ubuntu uses patched motd: https://wiki.debian.org/motd#How_to_scr … etc.2Fmotd and upstream PAM does not contain the patch with the dynamic motd. I will stick to the motd updated by cron job.
