I need to examine an 82.7 GB (!) text file. What can open it? We recently had a meltdown of a Tomcat server, that produced an 82.7 GB "catalina.out" log file, which I saved for forensic analysis.

What macOS editors can open monster text files without consuming 80 GB of RAM or causing 15 minute freezes?
less filename 

From the command line, it lets you view files straightaway without loading the full file into memory.
