I've got a log file that's managed to bloat upto 150MB. Is there a way to read only the last say 100 lines of the file instead of the whole thing? I don't want to have to download a 150 MB file with my current connection. I'd rather SSH in and read the relevant parts.
tail [filename]
To expand on Farseeker's answer:
tail -n 100 [filename]
to get the last 100 lines.
