Robert,
I don't know all the permutations of sed under solaris (there is /usr/bin/sed,
/usr/ucb/sed,
and /usr/xpg4/bin/sed).
The translation could be accomplished with "tr" and "sed" together, but the
following nawk
will work if you don't want another 3rd party sed to maintain:
cat obs200611132000 | nawk '{gsub("\r","\r\r"); print $0}' | dcmetr.......
The -m 72 bins data to 20 minute intervals, otherwise hourly bins are
used. There isn't currently a facility with dcmetr to not bin the times
(at that point, you'd probably do better by getting the actual obs rather than
a conversion of their obs back into metar).
