Yes, the old
Code:
while read rec; do 
    # process stuff
done < file

construct is notoriously slow and thus should only be used
on small to moderately big files.
I would go for Perl.
Without having looked too carefully at your processing,
and without even having tried for correct syntax
some Perl statement like this might do?
Code:
$ perl -ane 'push @ary,$F[1] if /3G/;END{$"="\n";print"@ary"}' file_to_read_from

mb_detect_order - Set/Get character encoding detection order

SYNOPSIS
mixed mb_detect_order ([mixed $encoding_list = mb_detect_order()]) DESCRIPTION
Sets the automatic character encoding detection order to $encoding_list. PARAMETERS
o $encoding_list -$encoding_list is an array or comma separated list of character encoding. See supported encodings. If $encoding_list is omitted, it returns the current character encoding detection order as array. This setting affects mb_detect_encoding(3) and mb_send_mail(3). mbstring currently implements the following encoding detection filters. If there is an invalid byte sequence for the following encodings, encoding detection will fail. UTF-8, UTF-7, ASCII, EUC-JP, SJIS, eucJP-win, SJIS-win, JIS, ISO-2022-JP For ISO-8859-*, mbstring always detects as ISO-8859-*. For UTF-16, UTF-32, UCS2 and UCS4, encoding detection will fail always. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 mb_detect_order(3) examples <?php /* Set detection order by enumerated list */ mb_detect_order("eucjp-win,sjis-win,UTF-8"); /* Set detection order by array */ $ary[] = "ASCII"; $ary[] = "JIS"; $ary[] = "EUC-JP"; mb_detect_order($ary); /* Display current detection order */ echo implode(", ", mb_detect_order()); ?> Example #2 Example showing useless detect orders ; Always detect as ISO-8859-1 detect_order = ISO-8859-1, UTF-8 ; Always detect as UTF-8, since ASCII/UTF-7 values are ; valid for UTF-8 detect_order = UTF-8, ASCII, UTF-7 SEE ALSO
mb_internal_encoding(3), mb_http_input(3), mb_http_output(3), mb_send_mail(3). PHP Documentation Group MB_DETECT_ORDER(3)
