Text Viewer for big size log file

Question

I have an application to generate a log file (text file) with three log flags: debug, warning and error. The debug flag is used to log detail information about application execution such as object values and status. The purpose of this flag is for debugging and support.

The problem is that if the flag is on, then it is possible to get a big size text log file. Last time I got 1GB size file. It was very hard to use notepad to view the file. Not sure if there is any text file view tool, preferably as open source, to view large size text file?

Answer 1

Notepad++ Can handle large files. And it has nice regex searching capabilities.

Answer 2

Textpad is a free text viewer that is very versatile (regex, hyperlinked find-in-files, etc) and can open large files. in any case, i would suggest using a split utility to break the file up into smaller pieces and use a find-in-files option on whatever utility you choose.

Answer 3

I am unsure of size limitations, but I frequently use TextPad(which is free) to view massive log files. If you really want open source, I would just use VIM.

Answer 4

UltraEdit uses a 64bit handle and therefore with the proper options set there is no real limit. From my own experience it stays really responsive while opening and browsing those files.
