The order is uninteresting, being determined by a hash function. -x catenates a hexadecimal ASCII representation of the information.

Normal operation is silent, indicating failure by a non-zero exit value. -v prints a brief synopsis of each conflict and a brief summary. -V additionally prints a hexadecimal ASCII representation of missing keys and conflicting contents, as in dbCatenate.

\b0 forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 is `-', the standard input is used. File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in each line. There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally consists of the common field, then the rest of the line from file1, then the rest of the line from file2. Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are discarded.
