tree-to-file.sh

A helper.sh-hosted shell script for Linux, macOS, and common Unix environments that exports a filtered directory tree into a text file. It prefers the system tree command, attempts installation through the available package manager when tree is missing, and still produces output through a built-in find plus awk fallback.

ワンライナー

curl -fsSL helper.sh/tree-to-file.sh | sh

curl -fsSL helper.sh/tree-to-file.sh -o tree-to-file.sh && sh tree-to-file.sh tree.txt 'venv|__pycache__|.git|.gitignore|docker|node_modules|.idea'

実行条件

Linux, macOS, or common Unix shell environment
sh
find
awk
Optional sudo or root for package installation

適用場面

Export a project structure into tree.txt for issue reports or AI context
Generate a shareable directory overview while skipping heavy folders
Keep a consistent tree export command across Linux and Unix-like hosts

主なポイント

Uses tree when available for familiar output
Attempts automatic installation through brew, apt, dnf, yum, pacman, zypper, apk, pkg, and other common package tools
Falls back to a built-in find plus awk renderer so the export still completes without tree

推奨手順

Fetch the script from helper.sh and run it with sh.
Let the script check whether tree is already available.
If tree is missing, allow it to install through the host package manager when possible.
Review the generated tree.txt in the current directory.

注意事項

Inspect the raw script before piping it into sh on sensitive hosts.
Automatic installation may require sudo or root and may refresh package metadata.
The built-in fallback matches ignore names exactly, not full shell glob patterns.
