When I try to check against lines, I get weird behavior. It is picking up the names of all the files in the directory where the test script lives. If I echo out the output variable, it looks perfect. If I echo out the lines varible with a for loop, it prints the names of all the files in the directory

for item in ${lines[@]}
do
echo "$item" >&3
done

filename1.sh
filename2.sh
actual output1
actual output2
filname1.sh
filname2.sh
actual output2
