thank you. this is the code i need. it works.

one question, where do you specify the "define host"? how does the script know where to begin?

i ask because in each chunks, there can be two ips set for one host. the ips will be specified by:

Code:

address  10.11.11.45
secondary_address 10.19.19.19

looks like the script only grabs any field that matches "address", when in fact, i need it to grab only the primary address, which is the "10.11.11.45".

It seems the script is grabbing the wrong IPs.

i modified the script to, instead of grabbing the primary ip that is defined in a chunk like this:

Code:

 define host {
      address 10.11.11.14
      alias mail-server
      host_name        mail-server01.sky.net
      use generic-host
}

i modified the script to grab the secondary IP instead. but its not working. it's grabbing ips that dont belong to the chunk of the particular host it is saying it belongs to.

Code:

 define host {
      alias mail-server
      host_name        mail-server01.sky.net
      _secondary_address 10.11.11.14
      use generic-host
}

here's my script, i'm sure its wrong:

Code:

  awk '
    NR == FNR { seen[$1]; next }   # collect hosts from the conf file
    /}/ {                        # end of chunk, if name was in conf list, print data
        if( name in seen )
            printf( "%20s ---- %s\n", name, ip );
        name = "F";
    }
    /host_name/ { name = $2; next; }
    / _secondary_address/ { ip = $2; next; }

' host.list host.conf

need help please
