The hard way :

Supposing the variable $rec1_field contains the field numbers delimited by a space as follow: "3 5 4 6 7":

Code:
awk -v var="$rec1_field" 'BEGIN{n=split(var,a)} 
NR > 1 {
  for(i=1;i<=n;i++) {
    printf("%s%c",$a[i],i==n?"\n":" ")
  }
}' file

devtakh,

Have you tried your solution?
The system command returns the exit code of the echo command, not the content of the variable.

You are right Franklin. This will return the exit code..
