+First do a sample in dry-run mode:
+
+ head -n25 /srv/fatcat/datasets/file_sha1_dupes.json \
+ | python -m fatcat_tools.mergers.files --editgroup-description-override "Automated merging of file entities with duplicate SHA-1 hashes" --dry-run merge-files -
+ # Counter({'updated-entities': 59, 'lines': 25, 'merged': 25, 'skip': 0, 'updated-total': 0})
+
+Gah, the dry-run mode still creates (empty) editgroups:

+ https://fatcat.wiki/editgroup/2mxsl7lxo5dezem42whnr7zxxe
+
+Actually run (merge) the sample:
+
+ head -n25 /srv/fatcat/datasets/file_sha1_dupes.json \
+ | python -m fatcat_tools.mergers.files --editgroup-description-override "Automated merging of file entities with duplicate SHA-1 hashes" merge-files -
+ # Counter({'updated-entities': 59, 'lines': 25, 'merged': 25, 'skip': 0, 'updated-total': 0})
+
+
+Run the full batch:
+
+ cat /srv/fatcat/datasets/file_sha1_dupes.json \
+ | python -m fatcat_tools.mergers.files --editgroup-description-override "Automated merging of file entities with duplicate SHA-1 hashes" merge-files -
+ # Counter({'updated-entities': 6197, 'lines': 2039, 'merged': 2014, 'skip': 25, 'skip-not-active-entity': 25, 'updated-total': 0})
