LogExpert GUI Alternative of Unix Tail Command For Windows

LogExpert is a file analyzing software that brings powerful tools to review log files, analyze events by date and time, and bookmark important log file content in order to keep check on errors and other discrepancies that occurred with applications being observed. It enables you to open multiple log files side by side for comparisons. With MDI based interface, you can keep track of multiple log files, compare them, differentiate each opened log tab by colors, evaluate generated events, and analyze log files of one specific session. It is an open source GUI replacement of Unix based tail command for Windows which lets you easily apply filters and search log file content by using regular expressions. The bookmark feature is the best amongst others. You can comment out a selected portion of long log file in order to mark down important changes. As we all know that randomly generated log files don’t comply with one specific log format standard, it features Columnizer option to quickly split log lines into columns to fit one well-defined log format. Additionally, it is very flexible in terms of using third-party plug-ins to use advance log related functions.

To open log file, click Open on toolbar and specify the log file. It adds a Line column to count the number of lines present in an opened log file. You can view as many log files as you want. The Follow tail command is not enabled by default, so you have to enable Follow tail checkbox present alongside show bookmark bubbles button on toolbar. You can also temporarily send a portion of log file to new tab to view and analyze one specific part of log file. The right-click menu lets you copy the selected part of log file, copy and move the selection to new tab, locate filtered line, load class in Eclipse IDE (if installed), and insert bookmark comment.
