+
+`od -v {{path/to/file}}`

+
+`od --format={{x}} --address-radix={{d}} -v {{path/to/file}}`
+
+- Display file in hexadecimal format (1-byte units), and 4 bytes per line:
+
+`od --format={{x1}} --width={{4}} -v {{path/to/file}}`
+
+- Display file in hexadecimal format along with its character representation, and do not print byte offsets:
+
+`od --format={{xz}} --address-radix={{n}} -v {{path/to/file}}`
