Question

I get this syntax error with my code – I’ve tried putting the quotes in various places but no luck. Can someone please assist. Thanks!

awk: non-terminated string  | grep Re... at source line 1
 context is
     >>>  <<< 
awk: giving up
 source line number 2

awk '/ (TCP|UDP) / { split($5, addr, /:/); 
cmd = "/bin/geoiplookup " addr[1] | grep 'Rev 1:' | sed 's/Rev 1: //g' " | awk -F', ' '{print $4",", $3",", $2}'; 
cmd | getline rslt; 
close(cmd); 
print $1, $2, $3, $4, $5, $6, rslt }' < "$IP_PARSED" >> "$BlockedIPs"

I think we’ve been here before. Don’t try to do complex processing inside the cmd. Use it to run your external command, then do the processing inside the main AWK program.

awk '/ (TCP|UDP) / { split($5, addr, /:/); 
cmd = "/bin/geoiplookup " addr[1] ; 
while (cmd | getline rslt) {
    if (rslt ~ /Rev 1: /) {
        gsub(/Rev 1: /, "", rslt)
        split(rslt, r, ",")
    }
}
close(cmd); 
print $1, $2, $3, $4, $5, $6, r[4], r[3], r[2] }' < "$IP_PARSED" >> "$BlockedIPs"
