Thanks Hanson44 - I could do it that way, but I was really hoping to assign $3 and $5 to shell variables inside the {} brackets (assuming that it is actually possible?)...

Just to make the picture a little clearer:
Code:
root[my-box]# cat /tmp/final_list
111.222.333.0
root[my-box]# pntadm -P 111.222.333.0 | head

Client ID       Flags   Client IP       Server IP       Lease Expiration                Macro           Comment

00A0BCDE1FGHI1  00      111.222.333.001    111.222.333.253     04/06/2013                      macro1
00              04      111.222.333.002    111.222.333.253     Zero                            macro1
00              00      111.222.333.003    111.222.333.253     Zero                            macro1
00A0BCDE1FGHI2  00      111.222.333.004    111.222.333.253     05/06/2013                      macro1
root[my-box]#

Present code:
Code:
while read line; do pntadm -P $line | awk '{if (( $2 == 00 && $1 != 00 ) || ( $2 == 04 )) print $3,$5}'; done < /tmp/subnet_list

The code I have a present should pick out three lines from above (IP's 111.222.333.001 ...002 and ...004).

Can anyone tell me how to assign $3 and $5 to shell variables, within the {} brackets - please? Smilie

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
