It's advised to always double quote variable in a shell script.
Code:
"$var"
The reason for that is treating shell code and shell data in variables equivalently! Not like in other languages that line of code is different entity/type of text than line of string stored under variable. Here it is the same.
In your case $str is expanded correctly with space at the end, but it is then just space in a command line, so it is discarded

md5
MD5(3) 1 MD5(3)md5 - Calculate the md5 hash of a stringSYNOPSIS
string md5 (string $str, [bool $raw_output = false])
DESCRIPTION
Calculates the MD5 hash of $str using the RSA Data Security, Inc. MD5 Message-Digest Algorithm, and returns that hash.
PARAMETERS
o $str
- The string.
o $raw_output
- If the optional $raw_output is set to TRUE, then the md5 digest is instead returned in raw binary format with a length of 16.
RETURN VALUES
Returns the hash as a 32-character hexadecimal number.
EXAMPLES
Example #1
A md5(3) example
<?php
$str = 'apple';
if (md5($str) === '1f3870be274f6c49b3e31a0c6728957f') {
echo "Would you like a green or red apple?";
}
?>

Secure password hashing
It is not recommended to use this function to secure passwords, due to the fast nature of this hashing algorithm. See here for
details.
