Cisco Show Log Command

This is such a simple cisco command, and I debated about actually making a post for it, but I know I’ll forget the syntax when I need it. I hope it helps you too:
To search through any file, you use the “include” command. The logs also show quite a bit of detail about what happened and this is useful for finding if an ACL has blocked your connection attempt for example.

1) how to disable the pagging? i mean if the logs are more than 1 page the log information stops at the 1st page, then we need to press space bar to continue to the next page. how to disable this? i want the logs to scroll down in a go.
2) what if i want to check only few last lines?
