Data Argument in shell script never blank

Hi All,

I have a script which accepts a parameter which can either be blank, a specific value, or a wildcard value. But it never seems to be blank and the wildcard option seems to return the names of matching files in my directory. This happens even with the worlds simplest script that just echoes the input, like this :

Code:
echo "you passed" $1

I get these results :

#. echo.sh gday
you passed gday

#. echo.sh *t*
you passed 17_11_06.dat

#. echo.sh *tt*
you passed *tt*


The last one was ok because I do not happen to have any files in my directory matching *tt*.

I would like the program to just accept the text as a parameter regardless. I have tried using quotes (eg "*t*") which is even worse as it returns ALL matching files !

Any assistance greatly appreciated ...

PARSE_STR(3)								 1							      PARSE_STR(3)

parse_str - Parses the string into variables

SYNOPSIS
void parse_str (string $str, [array &$arr]) DESCRIPTION
Parses $str as if it were the query string passed via a URL and sets variables in the current scope. Note To get the current QUERY_STRING, you may use the variable $_SERVER['QUERY_STRING']. Also, you may want to read the section on vari- ables from external sources. Note The magic_quotes_gpc setting affects the output of this function, as parse_str(3) uses the same mechanism that PHP uses to populate the $_GET, $_POST, etc. variables. PARAMETERS
o $str - The input string. o $arr - If the second parameter $arr is present, variables are stored in this variable as array elements instead. RETURN VALUES
No value is returned. EXAMPLES
Example #1 Using parse_str(3) <?php $str = "first=value&arr[]=foo+bar&arr[]=baz"; parse_str($str); echo $first; // value echo $arr[0]; // foo bar echo $arr[1]; // baz parse_str($str, $output); echo $output['first']; // value echo $output['arr'][0]; // foo bar echo $output['arr'][1]; // baz ?> SEE ALSO
