nawk help

What am I doing wrong here? I get syntax error.

I am trying to parse a file looking for the lines with "running" as the first field then print the 5th field, then looking at the 9th field for specific values and writing the whole line to a junk file.

nawk ';
{if ($1 == "running") print $1 >> ./junk1;
if ($9 == "S73isid") {print $0} >> ./junk1;
if ($9 == "S750vxpal.gridnode") {print $0} >> ./junk1;
if ($9 == "S75vxpal.StorageAgent") {print $0} >> ./junk1;
if ($9 == "S75vxsmfd") {print $0} >> ./junk1;
if ($9 == "S760vxpal.actionagent") {print $0} >> ./junk1;
print}' rc2.d_listing

Thanks!!

nawk -f bep.awk rc2.d_listing > ./junk1

bep.awk:
Code:
BEGIN {
  n=split("S73isid S750vxpal.gridnode S75vxpal.StorageAgent S75vxsmfd S760vxpal.actionagent", list)
  for(i=1; i<=n; i++) {
    list[list[i]]=i
    delete list[i]
  }
}
$1 == running { print $5; next}
$9 in list

sorry - copy/paste wrapped newline - edited the original post.

OK fixed the syntax error but
what I was hoping for is something like this
IP address (Field 5) then the "S" Files
ie:
196.196.1.10 S*
196.196.1.10 S*
196.196.1.10 S*
196.196.1.10 S*
196.196.1.11 S*
196.196.1.11 S*
196.196.1.11 S*
196.196.1.11 S*

Sorry, I have no idea what the "S" files are and I don't have a sample file you're trying to parse...
In your original code you're outputting the ENTIRE line (print $0) if the NINTH field is one of the matched strings.
And I think you wanted to output the 5-th field if the frst field is 'running'.

This is what I coded based on your explanation and a piece of code you've given.

If want you can provide a sample data file, a desired output and a description (once again) of what you're trying to achieve.
Please use vB Codes when posting any data samples.

Sorry for the misunderstanding!!

S* Stands for S73isid
S750vxpal.gridnode
S75vxpal.StorageAgent
S75vxsmfd
S760vxpal

if "running" output 5th field then if a match on the 9th field print the whole line is OK

I am getting the whole line and that is fine I just never get the 5th if running is 1st field..

Thanks!!!!
