LogViewer: Viewing And Searching Large Text files
Microsoft describes Logparser as a powerful, versatile tool that provides universal query access to text-based data such as log files, XML files and CSV files, as well as key data sources on the Windows operating system such as the Event Log, the Registry, the file system, and Active Directory. The results of the input query can be custom-formatted in text based output, or they can be persisted to more specialty targets like SQL, SYSLOG, or a chart.
LogViewer: viewing and searching large text files
UVviewsoft LogViewer can open large text log files. This log viewing tool supports Unicode filenames, forward and backward file searches, file printing, line wrapping, and several encodings, including ANSI, UTF-8, OEM, and Unicode LE/BE.
Disabling line numbers on large files will help make navigation much quicker. You can access this setting in Advanced Settings Editor display Miscellaneous: Disable line numbers.
If you plan to edit and move around quite a bit in large files, make sure to enable this option. UltraEdit requires more processing to calculate line numbers when moving to different places in extremely large files. This option disables line number calculation, and thus, improves performance.
To really free up resources for extremely large files, disable syntax highlighting completely (if your large file is source code with syntax highlighting). Disabling syntax highlighting will also automatically disable code folding and function listing as well.

Copies the selected lines as plain text to the Windows clipboard. If you're examining Configuration Manager and CCM log files, it copies the columns in the same order as the view. It separates each column by a tab character. Use this action when copying logs into email messages or other documents.
Show or hide all columns other than the log text. It also expands the log text column to the width of the window. Use this action when you're viewing logs on a computer with low display resolution. It displays more of the log text.
When you first open a log file, CMTrace replaces the Info pane by a progress bar. This progress indicates how much of the existing file contents it's loaded. The progress reaches 100 percent, CMTrace removes the progress bar, and replaces it with the Info pane. When you load large files, this behavior provides you with an indication of how long the load might take.
klogg is an open source multi-platform GUI application to search through all kinds of text log files using regular expressions. It has started as fork of glogg project created by Nicolas Bonnefon, and has evolved into a separate project with a lot of new features and improvements.
I've tried TextPad and UltraEdit so far. I've been using the former for years with much success, but the line number calculation seems to break when opening files larger than 10 GB. UltraEdit looks fine, but is very expensive (close to $100 per year). I'm wondering if there is a better/cheaper alternative.
Open very large text files with these 4 free Large File Viewer To Open Very Large Text Files. These file viewers can very easily open very large text files and log files (file size above 1 GB). Some of these file viewers not only allow you to view large text files but also let you edit them. Some even support Text Wrap to help us easily read the content in a flow. You can also search for lines containing specific word with some of these file viewers. One of these software even allow you to open more than one file in different tabs on its interface.
Our traditional text file viewers like Notepad and Notepad ++ are mostly of no use when you have to open very large files and logs (above 1 GB). This is where we need something that can easily open very large text files. That is why, I have compiled here a list of 4 free file viewers to easily open very large text files. These free large file viewers are, LogViewer, File Peeker, Glogg, and Large Text File Reader.
LogViewer is a free large file viewer to view large text files. It is a very lightweight open source Software. With LogViewer you can not only view large files quickly but also search for specific words. It also supports 4 type of Multi String Search, they are, Sub String Case Insensitive, Sub String Case Sensitive, Regex Case Insensitive, and Regex Case Sensitive Search. You can also use cumulative or progressive search if you want. It shows the total number of lines and also shows the duration it took to load the whole file.
File Peeker is a lightweight large file viewer software. It is quite fast in loading large text files as it only opens the portion of the text file you want to read. For that you need to specify, from where you want to read and how much you want to read.
Large Text File Reader is a lightweight large file viewer to open large text files (upto 10 GB). What makes it stand apart from other large file viewers is that it only opens a given number of line at a time. This way it becomes easy to go through a large text file.
All the above listed large file viewer can very quickly load large text files and log files. I personally liked Large Text File Reader as it is the most intuitive of them all, and it even allows you to copy text without the restriction of copying at least a line at a time.
BBEdit is pretty much the standard for opening large text files on a Mac. I've opened some good-sized files with it, and BBEdit didn't even break a sweat. It is not entirely free - you do not have to pay for a license unless you want features that are in the pro activation above and beyond the free license.
TextWrangler is a great tool for opening editing and saving large files. I wouldn't recommend if for copying and pasting large amounts of content though. Use it if you don't want to have to deal with the vi interface/commands. Like Loic mentioned, MacVim is a great app if you're more familar with vi.
If you are dealing with files over 2 GBs I recommend 010 Editor. It won't load the entire file in memory which means you can use it to open files larger than your available RAM and opening times will be much shorter (took about 20 seconds to open a 7GB file).
My first choice is SlickEdit. It looks, well, is a bit old fashioned, but I have seen no other editor that deals with large files (even GBs of text) that fast, and still giving a ton of features.
Most Linux log files are stored in a plain ASCII text file and are in the /var/log directory and subdirectory. Logs are generated by the Linux system daemon log, syslogd or rsyslogd.
The GVim editor is very useful for editing programs and other plain text files. All commands are given with normal keyboard characters, so those who can type with ten fingers can work very fast. Additionally, function keys can be defined by the user, and the mouse can be used.GVim. (Image Credit: Daniel Petri)
Timeline: Shows you the time range of the logs, represented byhistogram bars, that are currently displayed within the Query resultspane. The timeline helps to orient you to the logs you're currently viewingwithin the larger time range of your query.
Previously, when working with large log files (more than 1 million logs inside a single file), the Log Viewer's index could grow really big (reaching well over 100 MB in size for a multi-dimensional array in PHP) and thus increasing the memory usage for each request.
Filtering allows you to search on a specific field value instead of doing a full text search. This makes your log analysis more accurate because it will ignore undesired matches from other parts of the log message. To search on a field value, you need to parse your logs or at least have a way of searching based on the event structure. To do this, we can use awk.
Log management systems help simplify the process of analyzing and searching large collections of log files. They can automatically parse common log formats like syslog events, SSH logs, and web server logs. For example, SolarWinds Papertrail supports a live tail for all logs in a single consolidated view.
You can specify more search criteria, for example, by providing text in the Message text field, so you can search on explicit words or patterns across log files.You can specify more search criteria, as described in Searching Log Files: Advanced Searches.
ECID + Relationship ID - Groups messages by Execution Context (ECID) and Relationship ID (RID) which enables you to use log file entries to correlate messages from one application or across application server components. By searching related messages using the message correlation information, you can examine multiple messages and identify the component that first generated the problem. 350c69d7ab
