I don't see the need for the END clause for this problem. Doesn't:
Code:
awk 'c[$0]++{print}' ${TMP_DUPE_RECS}>${TMP_BAD_DATA_DUPE_RECS}

produce the same output?
When reading records, if the record has been seen more than one time, print it then.

But, looking at it again, this is the same as the script you initially provided that you said was not working.
If what you want is the input lines that are not duplicated that would be:
Code:
awk 'c[$0]++==0{print}' ${TMP_DUPE_RECS}>${TMP_BAD_DATA_DUPE_RECS}

which produces the output:
Code:
A
  A
  B
  C

which is not what was originally requested.

If there is only one word on each input line, and you want to print lines that are duplicates of previous lines (ignoring leading whitespace), try:
Code:
awk 'c[$1]++{print}' ${TMP_DUPE_RECS}>${TMP_BAD_DATA_DUPE_RECS}

which produces the output:
Code:
  A
  A
  B

but this still isn't the output originally requested. Please explain in more detail what it is that you want AND give us sample input and output that match your description.

SYNOPSIS
bool pg_copy_from (resource $connection, string $table_name, array $rows, [string $delimiter], [string $null_as]) DESCRIPTION
pg_copy_from(3) inserts records into a table from $rows. It issues a COPY FROM SQL command internally to insert records. PARAMETERS
o $connection - PostgreSQL database connection resource. o $table_name - Name of the table into which to copy the $rows. o $rows - An array of data to be copied into $table_name. Each value in $rows becomes a row in $table_name. Each value in $rows should be a delimited string of the values to insert into each field. Values should be linefeed terminated. o $delimiter - The token that separates values for each field in each element of $rows. Default is TAB. o $null_as - How SQL NULL values are represented in the $rows. Default is N ("\N"). RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 pg_copy_from(3) example <?php $db = pg_connect("dbname=publisher") or die("Could not connect"); $rows = pg_copy_to($db, $table_name); pg_query($db, "DELETE FROM $table_name"); pg_copy_from($db, $table_name, $rows); ?> SEE ALSO
