if you are using the Linux operating system, just open it with the less command:

less test.log
Under

windows, you can try start command:

start test.log

of course, there is also a general more command:

more test.log

isn't it sublime text??
I think we can try it. After all,
written by CPP or write a file segmentation tool yourself. Anyway, your log files are in behavior units, such as 10,000 behavior units. Split the log file into several files
and then analyze and retrieve the problem


ultraedit one by one, but you can definitely open it, but you can analyze this with the naked eye?
usually locates the problem first through tools such as linux's grep awk head tail . I don't know much about the windows tool chain, and I haven't used it.

Open a log file with Editplus yesterday, 1.02G. Editplus died on the spot.
opened successfully with notepad2. It's just that the high-occupancy software is automatically turned off. Like Chrome/idea.

the development machine stores 8G, i5 and SSD.

of course, it is recommended that you first use git-bash to filter out the key content using grep.
