I am a PhD student running jobs in a grid (~1500 jobs at any time). Some of the jobs go to error state which need to resubmit. The command to see the error jobs (from my local machine, in a terminal) is alien_ps -E which gives me this:   mhaque -762153733  __  EV                                      mhaque -762160371  __  EV                                      mhaque -762376874  __  EV .. so on..To resubmit the jobs I need to use the alien_resubmit $jobid (in my laptop terminal window). So I  use the following shell command:alien_ps -E | grep 'E' | sed 's/-//' | awk '{print alien_resubmit  $2}' which gives me:alien_resubmit 762153733alien_resubmit 762160371alien_resubmit 762376874.. so on..Then I copy paste this output to my terminal which then resubmit all those error jobs. Here is the real problem: I do not know when the jobs will go to error state. So I need to manually login to my laptop and check if any jobs went to error state and then resubmit it (within 24 hour or the grid kills the job). So, I would like to write a simple shell script testmyjob.sh which will loops this command for 5 minute intervals:alien_ps -E | grep 'E' | sed 's/-//' | awk '{print $2}'and see if there is any jobid. If no job is in error then it will do the check again after 5 min (and keep doing it for definite number of times say, 200 time after I executed the shell). If it finds error jobid then it will and run the command:alien_resubmit jobid         (..for all error jobs..).After submitting the error jobs, it will again resume the checking for error jobs for each 5min interval. So I will just run ./testmyjob.sh from my laptop/desktop terminal and it will keep working in the background, and relieve me from doing the checking by myself. I am not good at shell scripting. So please help me write a simple shell script which do this job. To be precise here is the block diagram:(pardon my shell knowledge)try = 0while(try<200) dojobid=alien_ps -E | grep 'E' | sed 's/-//' | awk '{print $2}'if(jobid is nonzero) alien_resubmit jobid   wait_for_5mintry+ = 1;end doPlease note there are always several jobs in error state (see the examples I gave) and I do not know how you will assign the jobs to one variable or make an array? Any kind of help with script is very much appreciated.
