Problem statement
What is the easiest way to export the current file tree into tree.txt on Linux or Unix-like hosts?
Use tree-to-file.sh when you want one command that checks for tree, tries the system package manager automatically, and still falls back to a built-in renderer if installation is not possible.
That makes it more useful than remembering a single tree command, because the same entrypoint works across mixed hosts and keeps the export flow repeatable.
What to check
- Export the current directory into tree.txt with one entrypoint.
- Auto-install tree when the host does not have it yet.
- Keep a fallback path when package install is not available.
