The script could look like:
Code:
#!/bin/bash

FILENAME=service.tra
S_PATH=/path/to/your/trace
D_PATH=/home/linus/gaurav

while :; do
   FOUND=$(find $S_PATH -type f -name "$FILENAME" -size +3000c -print)
   if [[ -n $FOUND ]]; then
      echo "File $FILENAME is larger than 3k - moving it."
      mv $FOUND $D_PATH
   fi
   sleep 3
done

exit 0

For infinite loops maybe put a sleep in there - else it might push your box to 100% CPU usage. In this example I use "find" but when the destination of the mv is also below this path, you'll get a problem, just as a site note. You might to use -purge in the find or check with ls -l or stat for the size of the file instead and check with -e if the file exists before that.

Code:
$one=`expr $one + 1`

Will not work since in a shell script there may be no spaces on the left or right of the equal sign. Also when declaring a variable there may be no $ in the name of the variable.
