var Cmd = &cobra.Command{

	Short: "find trie root hash from the wal files",
	Run:   run,
}

find trie root hash from the wal files. useful for state extraction and rolling back executed height. for instance, when extracting state for a target height, it requires the wal files has the trie root hash of the target block as the latest few records. If not the case, then it is necessary to trim the wal files to the last record with the target trie root hash. in order to do that, this command can be used to find the trie root hash in the wal files, and copy the wal that contains the trie root hash to a new directory and trim it to have the target trie root hash as the last record. after that, the new wal file can be used to extract the state for the target height.
