tre

tre [-a] [-l depth] [-e] [options] [path]

tre is a modern replacement for the classic tree command, written in Rust. It displays directory structures in a tree format with additional features designed for developer workflows, including editor integration and gitignore awareness.The editor integration mode (-e) numbers each file in the output and creates a shell alias that opens the corresponding file in your editor by number. Portable path mode (-p) outputs paths that can be directly copied and pasted into other commands.By default, tre respects `.gitignore` rules, filtering out ignored files for a cleaner view of project structures. Hidden files are excluded unless explicitly requested with -a.

-a, --all

Include hidden files.

Only list directories.

Maximum depth.

Editor integration (numbers files, creates aliases).

Exclude paths matching a regex. Repeatable.

Output JSON instead of tree diagram.

Portable absolute paths in editor aliases.

Ignore .gitignore rules.

Color output: automatic, always, never.

Not a drop-in replacement for tree — uses different flag names (e.g. -l instead of -L for depth). Respects .gitignore by default, which can be disabled with -s.
