Yup - use the "printf" function instead of "print".  "printf" takes 
arguments like the C language function to permit more advanced formatting
of your output.

To solve this problem, use

	awk '{printf "%s ",$1}' filename

This will print the first field of each record followed by a space.  To
include the newline at the end of the entire list, use the following variant:

	awk '{printf "%s ",$1}END{printf "\n"}' filename
