Trouble with nawk and OFS in BASH

I am working on a script to extract the processor set number followed by the processor ids that fall under that processor set in Solaris in bash shell:

Here is the output I want to extract from: (contents of $output)

user processor set 1: processors 0 1
user processor set 2: processors 2 8 9
user processor set 3: processors 3 4 5 6 7

Desired output is:

1: 0 1
2: 2 8 9
3: 3 4 5 6 7

The code i wrote using nawk:

print $output | nawk '                                 
BEGIN { ORS="\n" ; OFS = " " }
{
print$4; print OFS
for (i=6;i<=NF;i++)
print $i
}'

obtained output:

1: 
0 
1
2: 
2 
8 
9
3:  
3 
4 
5 
6 
7

Can anyone help and let me know what I am missing from obtaining the desired output . Thanks in advance.

ORS is already set to "\n" by default. Since you want to use multiple print statements you'll want to set it to the empty string since there's an implicit print ORS after any print statement.

print $output | awk '
    BEGIN { ORS=""; }
    {
        print $4;
        for (i=6;i<=NF;i++)
            print " " $i;
        print "\n";
    }'

You could also do this with cut:

print $output | cut -d ' ' -f 4,6-

Try this

print $output | nawk '                                 
BEGIN { ORS="\n" ; OFS = " " }
{
outrec = ""
for (i=6;i<=NF;i++)
    outrec = outrec " " $i
    print $4 " " outrec
}'
