replace \r\r\n with \r\n
I am having a dificult time trying to replace 2 carriage returns and 1 newline with 1 carriage return and 1 newline in a file. The file may come as CR NL in which case I need to leave it as is. When it comes with CR CR NL then I need to remove one of the CR's.
i tried
sed 's/\r\r\n/\r\n\g' file
but it has no effect on the file
appreciate the help. (I did search and tried many of the examples)
