Why isn't the "at" command sending data to the designated output file?

I am trying to use the "at" command to run a lengthy code (code.x) that will take values from an input deck (input_deck.in) and output the results to results.out. I have a text file labeled job.txt with the desired command. The contents of job.txt are as follows.

    ./code.x<input_deck.in>results.out

In the terminal I have 

    at -M -f job.txt now

The results.out file gets created but no output is sent to it. I am trying to understand the reason why, and how to make it so that the output gets sent to that file.

Thank you,

Kyle

Maybe your code.x does not have execute permission.

Add 2>error.log to the end of command, run at and then check error.log to see what is really going on.

# job.txt
./code.x < input_deck.in > results.out 2> error.log

# terminal
at -M -f job.txt now
cat error.log

You can remove 2>error.log after the problem being solved.
