nnn

nnn (or n³) is a full-featured terminal file manager. It's tiny and nearly 0-config with an incredible performance. See it in action on SFOS with dir/file preview enabled: https://asciinema.org/a/336443 (instructions for preview plugin on SFOS in the link).

nnn can analyze disk usage, batch rename, launch apps,  pick files, archive and decompress in various formats, bookmark, run batch operations, use SSHF, and a lot more. The plugin repository has tons of plugins and documentation to extend the capabilities further, e.g. preview hovered, (un)mount disks, find & list, file/dir diff, upload files. There's an independent (neo)vim plugin. nnn supports several tabs (contexts) with different colours, as well as multipane and cross-pane copy/paste in combination with tmux. viu (soon) can be used to preview images directly in terminal (example in screenshots).

Despite its capabilities, nnn is designed to be easy to use and is configured by way of enrivonment variables without a configuration file. Set options in your ~/.bashrc. It is very likely that nnn can do what you want already, but perhaps it is not default. Go see the wiki: https://github.com/jarun/nnn/wiki/. By default, nnn uses "rm" to delete files. If you find it too scary, you can install install Python tools (install pip with "devel-su zypper install python3-pip") to then install trash-cli with "devel-su easy_install trash-cli", and then enable the trash-cli support in nnn (see wiki).

On SailfishOS, nnn is most convenient with a hardware keyboard, but works too with the terminals featuring a virtual keyboard. nnn is very useful if you often ssh into your device too.

Convenience
- Run plugins and custom commands with hotkeys
- FreeDesktop compliant trash (needs trash-cli)
- Cross-dir file/all/range selection

Don't memorize! Arrows (or h j k l), /, q suffice. Tab creates, cycles contexts. ? lists shortcuts.

# Disclaimer
I am not the developer of nnn, I just packaged it for SFOS. nnn is being (very) actively developed by Arun Prakash Jara and contributors but that does not include the SFOS package, which may or may not be updated in the future.
