One other suggestion: you can use "od -cx" to see what "hidden" characters might be in your string.
echo 'A C'|od -cx
0000000 A C \n
<= THIS EXAMPLE CREATES THE STRING WITH THE CHARACTERS 0x41 ('A'), 0x20 (' ') AND 0x43 ('C'), THEN PIPES TO "OD" TO ECHO THESE CHARACTERS IN HEX AND IN ASCII
But I'm definitely curious where these "tokens" are coming from in the first place (my previous question).
Thx in advance .. PSM
