shell脚本编程问题，急求

脚本

shell

linux

有个问题，写了个shell脚本，执行是会有两个进程出现，

jboss5 7852 7678 0 18:01 pts/2 00:00:00 /bin/bash ./logzipok.sh
jboss5 7893 7852 0 18:01 pts/2 00:00:00 /bin/bash ./logzipok.sh

这是为是什么，之前没有这问题，在脚本中填入了下面函数，才有这问题，有人知道为什么吗？

removevar() {

mkdir -p /opt/applog/falconlog/logzip
local LOGFILE
LOGFILE=/opt/applog/falconlog/logzip/zip.log.$(date "+%Y%m%d")

if [ -d "/var/spool/clientmqueue/" ]; then
cd /tmp/
cd /var/spool/clientmqueue/ && ls | xargs -n1 rm -rf
echo "INFO:("$(date "+%Y%m%d %H:%M:%S")") rm the /var/spool/clientmqueue/ files." >> ${LOGFILE}
echo "--------------------------------------------------------------------" >> ${LOGFILE}
echo >> ${LOGFILE}
echo "${REMOTEVARNAME} $(date +%Y%m%d-%X) removevar1"

else
echo "no /var/spool/clientmqueue/"

fi

}
