help with simple awk script

Shell Programming and Scripting
1

Hi,
I just don't understand awk. I think I'm close here but can someone give me a hand to finish this little parsing routine ?

the input file is formatted like this:

District 2502110
Gsub 2384889
Gsub 1428180
District 2502220
Gsub 1466390
Gsub 1466389
Gsub 1466388
Gsub 1466386
Gsub 1466385
District 2502710

The script should make a command for each Gsub line that contains it's district.
Here's what I got but doesn't work.

Thanks !

awk '
{
  if (( $1 == "District" ))
  {
    dist=$2
    while (( $1 != "District" ))
    {
      sub=$2
      printf("dvmrgdel %s %s\n",sub,dist)
      getline
    }
   }
}' file

Post desired output from that input file. Also use code tags.

the desired output is:

dvmrgdel 2384889 2502110
dvmrgdel 1428180 2502110
dvmrgdel 1466390 2502220
dvmrgdel 1466389 2502220

So the Gsubs within a district print with their respective districts.

One thing I found out so far is my use of the variable "sub" won't work because sub is a command in awk. So I changed it to subm.

Code again:

nawk '
{
  if ( $1 == "District" )
  {
    dist=$2
    while ( $1 != "District" )
    {
      subm=$2
      printf("dvmrgdel %s %s\n",subm,dist)
      getline
    }
  }
}' list

Try this:

awk '/District/{d=$2; next} {print "dvmrgdel " $2 FS d}' file

That is an awesome piece of effecient code and works !!

Thank you very much !
