function echon { echo "$*" | awk '{ printf "%s" $0 }' }
You may prefer to avoid the overhead incurred when calling the awk command, however, and if you have a user-level command called printf you can use it instead:
echon() { printf "%s" "$*" }
But what if you don't have printf and you don't want to call awk? Then use the tr command:
echon() { echo "$*" | tr -d '\n' }
This method of simply chopping out the carriage return with tr is a simple and efficient solution that should be quite portable.
