Looking at your code I couldn't believe that it would run at all. But I tried "echo aaa > bbb ccc" and sure enough I created a file called bbb with the contents "aaa ccc". I never knew you could inbed redirects in the middle of an argument list.

That's what you are doing with "if [ $a > $b ]". You should be creating an output file. The [ is just a normal unix command that expects it's last argument to be ]. In the early days of the bourne shell, it was a link to the test command and sat in /usr/bin. Later it became a built-in, but it still is a command. It never understood > as a comparison operator. There is a -gt but it only works on integers and will barf on your time format.

You don't want an integer compare, you want an ascii string compare. So switch to [[ which is a keyword rather than a command:
if [[ $a > $b ]]
should work fine.

And it's korn, not korne. Smilie
