I use sed once in a while. It seems to always takes me forever to get
the command to work. I had a ASCII file that I needed to take out the
tabs (hex 09). The output file that sed created was EBCDIC. Finally
figured out I had to remove hex 05 not hex 09 to get it work. My 2
cents.

This is not an issue with sed... this will always happen character sets are
mixed.

sed "s:\\\\\.br\\\\:$(print '\\\r\\\n'):g" in.hl7 > out.hl7

I was hoping you'd come up with a solution, since mine (above) is so ugly.

:)

Best I can do is:
CRLF=$(print '\\r\\n'); sed "s:[\\][.]br[\\]:${CRLF}:g" < in.hl7 >
out.hl7

A little less ugly, methinks. But GNU has it beat hands down!

However, when I use this against a live file I have a
problem. The live file contains stand alone cr (x'0d')
as line delimiters.

A minor modification should resolve. Below is not tested.
CRLF=$(print '\\r\\n');
CR=$(print '\\r');
sed -e "s:${CR}:${CRLF}:g" -e "s:[\\][.]br[\\]:${CRLF}:g" < in.hl7 >
out.hl7
