##First I define some variables:

WorkDir=/u/myname/here/there
subdirName=XYZ
NB1=5
NB2=1000

for ID in `ls $WorkDir`; do


Not only is ls unnecessary, but it will break your script if any filenames contain spaces or other pathological characters.

Code:
for DIR in $WorkDir/*/$subdirName/

Code:
        #Define some variables specific to this iteration
        DIR=$WorkDir/$ID/$subdirName/


That is unnecessary if you use the line I suggested above.
Quote:
Code:
        OutFile=${DIR}somefile.txt

        export QUERY_STRING "workdir=$DIR&nb1=$NB1&nb2=$NB2"

Code:
export QUERY_STRING="workdir=$DIR&nb1=$NB1&nb2=$NB2"

Code:
        #call the executable, I extract some lines from its output,
        # and I fix them with perl regexprep:
        $Executable | tail -$(( $NBCLUSTERS*2+6 )) |
          head -$(( $NBCLUSTERS*2+4 )) |
           perl -pi -e 's/<b>|<\/b>//g' > $OutFile
        echo "Done!"
done

I just noticed the = in red, sorry! I changed my line into

export QUERY_STRING="workdir=$DIR&nb1=$NB1&nb2=$NB2"

and now everything seems fine.

Strange that before I didn't get any errors (strange and dangerous too!!)

Thanks guys for the help, I greatly appreciate it.

Is there a better way to strip out <b> and </b> symbols from the piped output besides calling perl?

Code:
$Executable | tail -$(( $NBCLUSTERS*2+6 )) | head -$(( $NBCLUSTERS*2+4 )) | perl -pi -e 's/<b>|<\/b>//g' > $OutFile

(By the way, I just click on the PHP button where I'm typing the message to capsulate my code, not because my code is PHP, now I just wrote [ code ] and [ /code ] manually)


As for using
Code:
for ID in `ls $WorkDir`; do

my reason is that I want to echo $ID on the screen after every iteration...

Code:
for ID in $WorkDir/*; do

gives the full directory name where $ID exists, so I will need to strip everything before the last /
