log = hello-chtc_$(Cluster).log
error = hello-chtc_$(Cluster)_$(Process).err

executable = hello-chtc.sh
arguments = $(Cluster) $(Process)
output = hello-chtc_$(Cluster)_$(Process).out

should_transfer_files = YES
when_to_transfer_output = ON_EXIT
# transfer_input_files = file1,/absolute/pathto/file2,etc

request_cpus = 1

request_disk = 1MB

Simple shell script executable: (hello-chtc.sh)
