What's the sed's equivalent? Thanks!
I thought only bash could do it, but I was wrong:
a=$'s/[ \r]\{1,\}$//'
sed $a
the shell will expand $'\r' to errr \r
and you can use as an one-liner
var=value sed $var

Yes, I used this in the past, but the ports' Makefiles are supposed to be ASCII-only :-( sed does not parse backslash-escapes except for \n which represents a newline. Is not that a bug really? There may be some legacy reasons not to do it by default, but I'd expect the -E flag to turn on the recognition of such symbols...

Try col(1) or tr(1) to remove the carriage return and then sed to remove the spaces. Well, yes, but that's a two-stage process.
