The practice tree uses touch -d and head -c 2M, which are GNU-only and fail on macOS. The environment ships it ready, so the lab works the same on any machine. Environment in entornos/linux-real/find-a-fondo: - armar-lab-find.sh builds ~/lab-find with the same block as the lab. arranque.sh runs it when the container starts, not at build time, so dates are relative to when you open it and -mtime -1 matches the page even if the image is days old. - lab-check looks for a find by size, by date and by type in ~/evidencia/evidencia-find.txt, and checks the challenge: one find with -size, -mtime and -exec ls -lh that shows viejo/grande.bin. - The smoke test passes with Docker: lab-check fails on a fresh container and passes with solucion.sh. Lab changes: - environment: in the frontmatter, and the setup step says it can be skipped inside the environment. - Evidence moves from ~/evidencia.txt to ~/evidencia/evidencia-find.txt, with the echo '$ command' pattern so lab-check can see the commands. - Drop its "Pendiente" row from entornos/README.md.

Probé el entorno con Docker: recién creado lab-check sale 1 y con solucion.sh sale 0. Sigue el patrón de grep-a-fondo. ¡Gracias!

Qué hace este PR
Suma un entorno con Podman para
