lnav VS duf

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.

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

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.

It looks like they run an SSH server inside a Docker container defined by this Dockerfile [1]. This uses the ForceCommand directive in the sshd_config file to ensure that a specific command is run when a user connects (rather than the user connecting directly to a shell).

Depending on whether the user connects as the `playground` or `tutorial1` user they interact with a bash script that is either [2] or [3].

Not sure these are really popular, but I cannot resist advertising a few utilities written in Go that I regularly use in my daily workflow:

- gdu: a NCDU clone, much faster on SSD mounts [1]

- duf: a `df` clone with a nicer interface [2]

- massren: a `vidir` clone (simpler to use but with fewer options) [3]

- gotop: a `top` clone [4]

- micro: a nice TUI editor [5]

Building this kind of tools in Go makes sense, as the executables are statically compiled and are thus easy to install on remote servers.

Somewhat related - `duf` is "a better `df` alternative":

I'm normally using duf but this looks pretty neat.

Otherwise the last option is to get the deb/appimage files from their official git repos or website, like for my use cases, MongoDB Compass (which was not officially maintained on flatpak) or duf (not available in Ubuntu repos)

duf

What cool CLI tools do you know, that are do something faster than regular commands, and do something useful? For example: https://github.com/muesli/duf.

duf - Disk Usage/Free Utility - a better 'df' alternative.
