USAGE : cdx cat [options...] [files...]
Combine files, one after the other. Do the right thing with file headers.

| -p | --pad=Mode> | Add trailing newline if absent. See below. |
| -n | --number=Name[,Start[,Where]] | Number the lines in column 'Name', starting at number 'Start', 'Where' can be 'begin' or 'end' |
| -b | --begin | Shortcut for --number number,1,begin |
| -e | --end | Shortcut for --number number,1,end |

| -s | --skip=Matcher | Do not number lines that match. |
The header mode dictates what file headers are expected, and what to do when files don't match each other
- Match -- First file can be anything, all other files must match the first one. This is the default.
- Require -- All files must have identical CDX headers
- Strip -- Strip CDX headers if present
- None -- The presence of a CDX header is an error
- Trust -- Strip CDX headers from all but first file. Trust that the data is compatible.
- Ignore -- Treat CDX Headers just like any other line of data
What to do if files don't end with a newline
- Yes - Always append a newline if one isn't present. This is the default.
- No - Never append a newline.
- End - Appen a newline to the last file, if necessary.
