Thank you all for an evaluation
Probably there should replace the heavyweight utility "xargs" and wrap everything in a function
like so
Code:
#!/bin/bash
prt() {
        str=$(seq -s"{$1..$2}" $3)
        eval echo ${str//[0-9]}
}
prt a e $((3+1)) | fmt -1 | sed 's/./& /g'

Or insert a loop "for in" as suggested above.
In ksh93 works too

mb_strtolower - Make a string lowercase

SYNOPSIS
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 ?> SEE ALSO
mb_strtoupper(3), mb_convert_case(3), strtolower(3). PHP Documentation Group MB_STRTOLOWER(3)
