Here is an example (Note: '-n 1' is needed for srun command. It make sure only run one copy of the commands.):

Create a file with ( you can replace "echo firstCommand; echo secondCommand' with your own commands):

srun -n 1 -t $SRUNTIME --mem $SRUNMEM bash -c "{ echo I am running on:; hostname; echo firstCommand; echo secondCommand; } && touch myJob.success" 
sleep 5 # wait slurm get the job status into its database
echo Job done. Summary: 
sacct --format=JobID,Submit,Start,End,State,Partition,ReqTRES%30,CPUTime,MaxRSS,NodeList%30 --units=M -j $SLURM_JOBID 
sh myJob 
[ -f myJob.success ] && exit 0 || exit 1 

Create a file with: 

to=`cat ~/.forward`
actualsize=`wc -c $flag.out`
[ ! -f $flag.success ] && s="Subject: Failed: job id:$SLURM_JOBID name:$SLURM_JOB_NAME\n" ||  s="Subject: Success: job id:$SLURM_JOBID name:$SLURM_JOB_NAME\n"
stat=`tail -n 1 $flag.out`
[[ "$stat" == *COMPLETED* ]] && echo *Notice the sacct report above: while the main job is still running for sacct command, user task is completed. >> $flag.out

if [ "${actualsize% *}" -ge "$minimumsize" ]; then
   toSend=`echo Job script content:; cat $`
   toSend="$s\n$toSend\nOutput is too big for email. Please find output in: $flag.out"  
   toSend="$toSend\n...\n`tail -n 6 $flag.out`"
   toSend=`echo Job script content:; cat $; echo Job output:; cat $flag.out`
echo -e "$toSend" | sendmail $to 

Then submit with (notice here, SRUNTIME Is 1 minute less than sbatch time and SRUNMEM is 1M less than sbatch mem.This is to make sure srun will not use more all the resource, so sacct and email commands can run.): 

export SRUNTIME=0:9:0; export SRUNMEM=500M; sbatch -p short -t 0:10:0  --mem 501M -o myJob.out -e myJob.out
