  78 6,749 9.6 C++

  Log file navigator

Project mention: Ask HN: Interesting TUIs (text user interfaces), maybe forgotten ones? | news.ycombinator.com | 2024-05-06

The Logfile Navigator (https://lnav.org) is a log file viewer/merger/tailer for the terminal. It has some advanced UX features, like showing previews of operations and displaying context sensitive help. For example, the preview for filtering out logs by regex is to highlight the lines that will be hidden in red. This can make crafting the right regex a bit easier since the preview updates as you type. lnav also has some simple bar charting abilities, so you can visualize the results of SQL queries made against the log messages.

  Really fast log explorer based on glogg project

Project mention: Toolong: Terminal application to view, tail, merge, and search log files | news.ycombinator.com | 2024-02-09

I'd love to see a tool that lets you modify large files efficiently.

I had to replace line 4 of a 200 GB SQL dump, it took a substantial amount of compute time to perform a find / replace with sed and it also required having over double the disk space since sed creates a temp file before it writes out the new file.

Using a hex editor could have worked but it seemed too risky because data integrity was really important.

There's also some other scenarios where maybe you have a massive file and the tool that's using it (such as a SQL import) throws an error on line 1,025,421. Trying to find what the contents of that line is on the command line could be time consuming if you need to read in the whole file. For read operations I know there's a few graphical tools like https://github.com/variar/klogg that efficiently let you scan, search and jump to points in a file quickly but I haven't found a good one on the command line.

Project mention: Ask HN: What side projects landed you a job? | news.ycombinator.com | 2023-12-03

I wrote a Kibana plugin - https://github.com/sivasamyk/logtrail and few graylog plugins which opened many doors for me. It also helped me land my last job at The Sematext. I lost interest in maintaining the plugin after Elastic's open-source license changes.
