When I run this command manually here is the response:
Code:
 

[emily04@cmslpc38 pythia]$ jobNo=$(awk '/Jobs with Wrapper/ && $NF != 0{s=1}   /List of jobs/ && s{if(p){p=p","$NF}else{p=$NF};s=""}END{print p}' qcd120_status.log )
[emily04@cmslpc38 pythia]$ echo $jobNo

[pooja04@cmslpc38 pythia]$

Which I want from the SCRIPT too.
Hi Emily.

I will assume you meant "Don" rather than "Dan".

Yes, I understand the output you want.

And again, the function is defined as following in the script:
Code:
ResubmitJobs() {
 crab ntuplize_crab -status -c $SAMPLE >& $SAMPLE"_status.log" &   <--- Remove this ampersand!
  echo "---------Will Resubmit the Jobs--------------"
                                       
    echo $SAMPLE"_status.log" "====="
    
    jobNo=$(awk '/Jobs with Wrapper/ && $NF != 0{s=1}   /List of jobs/ && s{if(p){p=p","$NF}else{p=$NF};s=""}END{print p}' $SAMPLE"_status.log" )
    #sleep 200                                                                                                                                        

    echo $jobNo "====="
    echo $jobNo "====="

I hope it is easy for you now to understand it.

greetings,
emily
Yes, I understand. And, as I said before, if you remove the ampersand marked in magenta above, you will get the output you want. Your problem is that awk is processing $SAMPLE"_status.log" before the crab command writes any data into it. You are running crab and awk concurrently instead of letting crab complete before letting awk read the data that crab will eventually produce.
