+`pcapfix {{path/to/file.pcapng}}`
+
+- Repair an entire `pcap` file:
+
+`pcapfix --deep-scan {{path/to/file.pcap}}`
+
+- Repair a `pcap`/`pcapng` file and write the repaired file to the specified location:
+
+`pcapfix --outfile {{path/to/repaired.pcap}} {{path/to/file.pcap}}`
+
+- Repair a `pcapng` file and treat it as a `pcapng` file, ignoring the automatic recognition:
+
+`pcapfix --pcapng {{path/to/file.pcapng}}`
+
+- Repair a file and show the process in detail:
+
+`pcapfix --verbose {{path/to/file.pcap}}`
