This looks like a continuation of your earlier thread in September (rather than homework/coursework).
Here is an awk script that does a merge like you want:
Code:
#!/bin/sh
awk '
$1=="}" { bl-- }
bl>0 {
  # we are within a { } frame
  if ($1=="EqName") {
    eqname=$0
  } else if ($1=="Id") {
    id=$0
  } else {
    # ORS is a newline
    key=(eqname ORS id)
    if (key in store) {
      # append string
      store[key]=(store[key] ORS $0)
    } else {
      # new string
      store[key]=$0
      # enforce the original order with a number-indexed array
      ind[++cnt]=key
    }
  }
}
$1=="{" { bl++ }
END {
  # walk through the number-indexed array
  # "for (key in store)" would be a random order
  for (c=1; c<=cnt; c++) {
    key=ind[c]
    print "POLY_STATS"
    print "{"
    print key
    print store[key]
    print "}"
  }
}
' file

The { } frame and the text outside are hard-coded in print statements.

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   activate <name> activate script.

	   deactivate deactivate all scripts.

       -r realm, --realm=realm
