Yes each line matching "cert_codes" will be stored in aa.txt.
But multi lines will not be grepped .Check example given below, here even though it's a multi line where 'robert' appears only robert was grepped and 'bob' missed out.
Is this what you were looking for ?
$> cat test.sh
ary=("robert" \
" bob")
for a in ${ary[@]}
do
echo $a
done
$> grep robert test.sh
ary=("robert" \

LEARN ABOUT PHP
mb_detect_order
MB_DETECT_ORDER(3) 1 MB_DETECT_ORDER(3)
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
