# Reading the disk You can read files from a run's disk without touching the run. Reads are pinned to a snapshot, so they never change how the machine executes. ```bash machine artifacts ls app /var/log machine artifacts cat app /var/log/app.log machine artifacts cp -r app /results ./results ``` Add `@ref` to the run to read the disk as it was at a checkpoint or an entry. ```bash machine artifacts cat app@booted /etc/hostname machine artifacts ls app@4200 /tmp ```
