Going through script files and appending results to logfile

I'm trying to write a script that goes through 5 script files and executes them using the contents of t1-5 as inputs and appends the outputs to a log file but it doesn't seem to be working. I'm trying to increment a variable i representing the number of the t variables. Am I doing that right? And is this output redirection making sure that all the results are appended to the same file?

t1=`cat t1`
t2=`cat t2`
t3=`cat t3`
t4=`cat t4`
t5=`cat t5`

cd ..
cd tmp

i=1

for g in `ls`
do
    sh "$g" "t$i" > 0572log 
    i=$((i + 1)
done

First, i=$((i + 1) should be i=$((i + 1)).

Second, > 0572log should be >> 0572log in order to append and not overwrite.

Third, if you expect to run the script more than once it would be best to put 0572log somewhere else (e.g. ../0572log), and not in your tmp directory. Otherwise, the next time you run the script it will try to execute 0572log.

The quotes around $g and t$i are not required if you have simple file names without whitespace.
