Here' s what I get:
+ OLDIP=<tr height=60 align=center valign=top> <td height=60 align=center> 60.228.7.242 <tr height=60> <td height=60 align=center> <tr height=60 align=center valign=bottom> <td height=60 align=center>
+ '[' '<tr height=60 align=center valign=top>
<td height=60 align=center>
60.228.7.242
<tr height=60>
<td height=60 align=center>
<tr height=60 align=center valign=bottom>
<td height=60 align=center>' '!=' '<tr height=60 align=center valign=top> <td height=60 align=center> 60. 228.7.242 <tr height=60> <td height=60 align=center> <tr height=60 align=center valign=bottom> <td height= 60 align=center>' ']'
+ /devbin/wget

So even though IP and OLDIP seem to be the same, it goes on to the next line (wget) when I think it should just exit.
