interestingly, soda.csua.bekeley.edu had logging by 1993. and the mechanism? a complete rewrite of wall as the redundantly named wallall, which wrote to a log file right after it wrote to all the ttys. that way there was no need to snarf a pty just to log.<p>and by the way, i don&#x27;t agree that it&#x27;s ok to log any public stream just because it&#x27;s public. some public media don&#x27;t feel like a medium of record, and invite an informal behavior that their users would regret if they knew they were being logged. if i knew everything i&#x27;d say in public could be held against me forever, i&#x27;d say very different things.
