> the getmerge command (
> https://github.com/apache/hadoop/blob/6d116ffad23b470f8e9ca131d8e89cbbbb4378d7/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/shell/CopyCommands.java#L53-L142
> ) should support writing to stdout as well as to a local file.
> You can do this now by providing a path of /dev/fd/0, /dev/stdout, or some
> named pipe, but those can be somewhat inconvenient and nonportable. (E.g.
> writing to /dev/stdout tries to write /dev/.stdout.crc when I run it).
> I suggest that when called with "-" as the destination path, getmerge writes
> all output directly to stdout.
