2 bash shell scripts with kill-trap

[basak]

Hi:) Well this is my first thread in this community so forgive me if I make any mistakes.:)

I wrote 2 scripts ; "mycommand" and "traptest" as below.

#!/bin/bash
#mycommand

calledprg=
while [ "$1" != "" ]; do
     case $1 in
                     -s )         shift
                                        calledprg=$1
                   ;;
                      * )          exit 1

                 esac
                  shift
done

    if [ "$calledprg" != "" ];then
    pkill -s 1 $calledprg
    fi
exit






#!/bin/bash
#traptest

PROGNAME=$(basename $0)
echo "$PROGNAME"
trap ' echo "byeeeeeeeeeee"  ; exit ' SIGHUP


mycommand  -s $PROGNAME 
while :
do
        echo "sleeeeppppp"
        sleep 60
done

but traptest never gets out of the loop even I want it to exit when mycommand sends it a signal.If you have any ideas about the problem I would be so happy to hear them:)) Thank u:)
