Emacs读取大文件〜14GB [英] Emacs To read Large Files ~14GB

问题描述

最近我已经下载了我的系统上的emacs来编辑大文件，因为它声称。当尝试打开大文件时，emacs给我一个超出缓冲区大小的问题。

有没有办法增加它？我有一个内存为24 GB的系统！

解决方案

为什么要编辑大量的14Gb文件？我相信想要这样做是错误的。

你没有时间阅读这么大的文件的所有（甚至大多数）。它是什么样的文件？ （一些日志文件，一些MySQL转储文件???）

所以你正在搜索该文件中的一些特定模式。自己一个忙，写一个脚本（甚至一个程序）来做这个，并编辑（如果有关的话）你需要的大文件...

很可能你不在乎大部分文件的内容。

或将文件拆分成较小的部分（例如，使用 csplit ），以及编辑相关较小的块，然后使用 cat

重建巨大的文件

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!

解决方案

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 with cat
