Bash & Scripting · easy · solved in-browser (no VM needed) · 3 tiered hints
Write /home/player/logger.sh whose first line is the env-bash shebang #!/usr/bin/env bash. Define a `log()` function that timestamps each message with `date`, formats the line with `printf` using a `%s` specifier, and writes to standard error by redirecting with >&2. (Authored config, graded structurally — the engine isn't run here.)
