bash script exits before completion

Question

I'm new to shell script, and I tried to understand why it stopped running after the command which submits a job into Gaussian (a computational chem program). Here is my code.

echo "hi, the script is running..."
location=$(dirname $1)
echo $location
g09 <<EEE 
%chk=test2
$(cat $1)
EEE
echo $?
echo "done"
echo "need help??????" >tttt.txt

It doesn't show the last three echos, while the computational program terminates normally.

My assumption is when the program quits, my script is terminated as well. But is it possible? How should I get it around??

Answer 1

Alright, so it's been a while and I think I should close this question since by the suggestion from @Charles Duffy , I added shebang line and clean up the format by checking if there's any cr/lf problem (I was writing the script on Windows). Yes, that solved the problem. Thank you Charles!
