How to test the output of gnu parallel

[yacob sen]

Dear All,

I am trying to test if a file exists or not in a remote server. I have 4 processors on my disposal in my laptop. Here is what I am trying to do:

for  value  in {10..20}

do

#*************************************************************************************************

seq -w 1 1 100 | parallel  -j+0  wget ${ftp_site}/$value/{}/{}.F >& /dev/null  && echo  Y >> tmp || echo  N  >> tmp

          read test < tmp

         if [ $test = "Y"  ];then 

           echo "to an output  file, "temp.$value.{}""

         fi

done

#*************************************************************************************************

If the file exists in the remote server, the value in "tmp" should get "Y" , in that case the file is saved to a file.  My question is how to test the existence of all the 4 processors at the same time ?

"temp.$value.{}"  "{}" should take the sequence that comes from "seq -w 1 1 100"

Any help is very much appreciated.

Kind regards

Yacob
