+
+The `influxd inspect dumpwal` command outputs data from Write Ahead Log (WAL) files.
+Given a list of file path globs (patterns that match `.wal` file paths),
+the command parses and prints out entries in each file.
+
+## Usage
+```sh
+influxd inspect dumpwal [flags] <globbing-patterns>
+```
+
+## Output details
+The `--find-duplicates` flag determines the `influxd inspect dumpwal` output.
+
+**Without `--find-duplicates`**, the command outputs the following for each file
+that matches the specified [globbing patterns](#globbing-patterns):
+
+- The file name
+- For each entry in a file:
+	  - The type of the entry (`[write]` or `[delete-bucket-range]`)
+	  - The formatted entry contents
+
+**With `--find-duplicates`**, the command outputs the following for each file
+that matches the specified [globbing patterns](#globbing-patterns):
+
+- The file name
+- A list of keys with timestamps in the wrong order 
+
+## Arguments
+
+### Globbing patterns
+Globbing patterns provide partial paths used to match file paths and names.
+
+##### Example globbing patterns
+```sh
+# Match any file or folder starting with "foo"
+foo*
+
+# Match any file or folder starting with "foo" and ending with .txt
+foo*.txt
+
+# Match any file or folder ending with "foo"
+*foo
+
+# Match foo/bar/baz but not foo/bar/bin/baz
+foo/*/baz
+
+# Match foo/baz and foo/bar/baz and foo/bar/bin/baz
+foo/**/baz
+
+# Matches cat but not can or c/t
+/c?t
+```
+
+## Flags
+| Flag                | Description                                            |
+|:----                |:-----------                                            |
+| `--find-duplicates` | Ignore dumping entries; only report keys in the WAL that are out of order. |
+| `-h`, `--help`      | Help for `dumpwal`.                                    |
