Track user log!

Aha, what if i use $(users | wc -l)
coz, who returns me on two consoles tty7 and pts/0
How can i separate the files, the Today.txt must contain users who were logged in today
and Yesterday.txt must contain yesterday logs, and i should have no more than 2 days old logs.
Something like if [ $(date +%Y%m%d).log -ge than 48h ]; than delete it?
How can i tell if a file is older than 2 days?
---------- Post updated at 03:58 PM ---------- Previous update was at 02:40 PM ----------
it would be even better if i rewrite from today.txt into yesterday.txt, but only when
24 hours passes and the today.txt will be blank.
What i mean is...i must keep track of the users for 24 h and then rewrite it
to a yesterday.txt file!
How is that doable???
