[ale] string escaping - part 2

[Christopher Bergeron]

Everyone, thanks for the help!  Here's the bizarre thing:  When I echo that
to a file it works properly, but when I send it to a command, it fails.
Here is the script:

#!/bin/bash
d=`date +%D`
t="'text 50,50 \"$d\"'"
mogrify -draw $t /root/jet/max.gif
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ should work (but doesn't)

#this section below makes it work because the mogrify line above fails....
go figure?
echo mogrify -draw $t /root/jet/max.gif > /root/jet/temp.sh
chmod 755 temp.sh
/root/jet/temp.sh
rm -rf /root/jet/temp.sh



This script simply puts the current date on top of a gif image (max.gif).
The part that gets me is how when I execute the line:

mogrify -draw $t /root/jet/max.gif

in the script it fails to replace the $t with 'text "06/21/01"'

when I echo the EXACT same line to a file and then execute it, it works
fine.
Go figure...?  For those wondering, the command that I'm trying to execute
is:
bash# mogrify -draw 'text 50,50 "current_date_here"' max.gif


If you know why, I'd love to know... thanks.
