LNAV Reviews and details

Social recommendations and mentions

• ht: Headless Terminal

  As others have kinda alluded to, it could be useful for testing TUI applications. I develop a logfile viewer for the terminal (https://lnav.org) and have a similar application[1] for testing, but it's a bit flaky. It produces/checks snapshots like [2]. I think the problems I run into are more around different versions of ncurses producing slightly different outputs. [1] - - Source: Hacker News / 3 days ago

• Ask HN: Interesting TUIs (text user interfaces), maybe forgotten ones?

  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... - Source: Hacker News / about 1 month ago

• Angle-grinder: Slice and dice logs on the command line

  See https://lnav.org for a powerful mini-ETL CLI power tool; it embeds SQLite, supports ~every format, has great UX and easily handles a few million rows at a time. - Source: Hacker News / about 1 month ago

• Toolong: Terminal application to view, tail, merge, and search log files

  The code base seems like a good reference as a small Python project. My fav option in this class of apps: https://lnav.org/ It lets you use journalctl with pipes as requested here: https://github.com/Textualize/toolong/issues/4. - Source: Hacker News / 4 months ago

• Logdy.dev – web based logs viewer UI for local development environment

  For local development, I cannot recommend lnav[1] enough. Discovering this tool was a game changer in my day to day life. Adding comments, filtering in/out, prettify and analyse distribution is hard to live without now. I don't think a browser tool would fit in my workflow. I need to pipe the output to the tool.

• Logdy.dev – web based logs viewer UI for local development environment

  If it's just files, lnav [1] is pretty good. [1] https://lnav.org/. - Source: Hacker News / 4 months ago

• Textanalysistool.net

  Https://lnav.org/ Is a good Linux command line tool in the same genre. - Source: Hacker News / 5 months ago

• Show HN: Tailspin – A Log File Highlighter

  This is really pretty - I do really wish for a good rust replacement for lnav[1] someday. 1: https://lnav.org/. - Source: Hacker News / 7 months ago

• Ask HN: How does `lnav` run its playground which you can just SSH into?

  Https://lnav.org/ has a feature that single handedly sold me on trying out the fantastic software: An SSH-reachable playground. It's right there above the fold on the first page: ssh://playground@demo.lnav.org I want to build a similar playground for people who want to get familiar with the tools my Shell Bling Ubuntu repo provides ( https://github.com/hiAndrewQuinn/shell-bling-ubuntu ). Ideally it consists of a... - Source: Hacker News / 7 months ago

• Cosmopolitan Third Edition

  > all so that the same binary runs on multiple operating systems, which isn’t actually very useful. I like to mention my use case when this comes up: my log file viewer (https://lnav.org) uploads an agent to remote hosts in order to tail log files on that host[1]. While lnav itself is not built using cosmo, the agent is. So, it works on multiple OSs without having to compile and include multiple versions of the... - Source: Hacker News / 7 months ago

• Ask HN: What cool software utilities have you created?

  The Logfile Navigator (https://lnav.org), a logfile viewer for the terminal. Started it in 2006 and have used it most every day since to view the logs of whatever software I was working on at the time. - Source: Hacker News / 10 months ago

• Patching GCC to Build Portable Executables

  I use an APE executable as an agent for communicating with remote hosts in the Logfile Navigator (https://lnav.org). While lnav itself is not built as an APE, the agent built into itself is. That agent is transferred to the remote when the user wants to read logs on that host. This way, there is no extra step to determine the type of OS or building in multiple versions of the executable. Here's a short blog... - Source: Hacker News / 11 months ago

• simple app for monitoring server log?

  Https://lnav.org/ really whips the llama's ass. Source: 11 months ago

• What are you rewriting in rust?

  I'm the author of the Logfile Navigator (https://lnav.org). It's C++ and was started in the mid-2000's. I started playing around writing a new version in Rust a few months ago, but haven't gotten back to it in a while. Source: 11 months ago

• Log viewing application

  I'd be interested in a native Mac app that does this. That said, lnav is quite powerful and reasonably easy to use and can grab a directory of log files from a remote server over SSH. Source: about 1 year ago

• Analyzing multi-gigabyte JSON files locally

  LNAV (https://lnav.org) is ideally suited for this kind of thing, with an embedded sqlite engine and what amounts to a local laptop-scale mini-ETL toolkit w/ a nice CLI. I've been recommending it for the last 7 years since I discovered this awesome little underappreciated util. - Source: Hacker News / about 1 year ago

• Searching through JSON logs locally

  I had 2 options on my mind: local ELK and lnav. I tried to google about how to quickly run ELK in Docker locally (I had no prior experience in setting ELK up), but haven't found good tutorials. I believe they exist, but I also was thinking about possible caveats. - Source: dev.to / over 1 year ago

• Show HN: Log collector that runs on a $4 VPS

  May be more widely applicable for personal servers: lnav, an advanced log file viewer for the terminal: https://lnav.org/ It uses SQLite internally but can parse log files in many formats on the fly.

• Tools for "static" log analysis

  Not sure if this is what you're looking for, but I came across this awesome little tool called lnav (Logfile Navigator) that might be of interest: https://lnav.org/. Source: over 1 year ago

• Show HN: Ov – feature rich terminal pager

  I'm a fan of lnav, more for log files but incredibly useful: https://lnav.org/. - Source: Hacker News / over 1 year ago

  If the log-file viewing capabilities look interesting to you, check out lnav, which is built for that and excels at it: https://lnav.org/. - Source: Hacker News / over 1 year ago
