Could you explain the part
of your command line please, it's confuse for me.
I've understood that for each block /BEGIN/,/END/ you do this { str = str ? str "\n" $0 : $0 }, i know the result but it's not clear for me
Thx.
The condition ? trueaction : falseaction exists in awk like in C.
str gets the concatentation of str "\n" $0 if str is not null (undefined, empty, or 0), otherwise it gets $0.
$0 is the entire line.
BTW it will misbehave if the line is 0; better is { str = (str != "") ? (str "\n" $0) : $0 } but still has problem with empty lines.
That's why I prefer the { str = str sep $0; sep="\n" } method.

mb_strtolower
MB_STRTOLOWER(3) 1 MB_STRTOLOWER(3)mb_strtolower - Make a string lowercaseSYNOPSIS
string mb_strtolower (string $str, [string $encoding = mb_internal_encoding()])
DESCRIPTION
Returns $str with all alphabetic characters converted to lowercase.
PARAMETERS
o $str
- The string being lowercased.
o $encoding
-The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.
RETURN VALUES
$str with all alphabetic characters converted to lowercase.
UNICODE
For more information about the Unicode properties, please see http://www.unicode.org/unicode/reports/tr21/.
By contrast to strtolower(3), 'alphabetic' is determined by the Unicode character properties. Thus the behaviour of this function is not
affected by locale settings and it can convert any characters that have 'alphabetic' property, such as A-umlaut (A).
EXAMPLES
Example #1
mb_strtolower(3) example
<?php
$str = "Mary Had A Little Lamb and She LOVED It So";
$str = mb_strtolower($str);
echo $str; // Prints mary had a little lamb and she loved it so
?>
Example #2
mb_strtolower(3) example with non-Latin UTF-8 text
<?php
$str = "Txiotn a
nE Baos unuvn yn, dpaokeCei unp vw0po kuvs";
$str = mb_strtolower($str, 'UTF-8');
echo $str; // Prints txiotn a
nE Baos unuvn yn, dpaokeCei unp vw0po kuvs
?>
