Recently I have downloaded emacs on my system to edit large files as it claims. When trying opening large files, the emacs gives me a problem that buffer size is exceeded.
Is there a way to increase it?! I have a system with memory of 24 GB!
Why do you want to edit huge 14Gb files? I believe it is wrong to want to do that.
You don’t have the human time to read all (or even most) of such a huge file. What kind of file is it? (some log file, some MySQL dump file???)
So you are searching some specific pattern inside that file. Do yourself a favor, write a script (or even a program) to do that, and to edit (if relevant) your big file where needed…
Very probably, you don’t care of most of the content of that huge file. Only a few lines matter to you.
Or split the file into smaller pieces (e.g. with
csplit), and edit the relevant smaller chunks, then rebuild the huge file withcat
