使用参数作为函数内部变量的一部分

Question

如果我输入：

function chk_is_it_started(){
PROCC_NAME_$1="my_process_$1";
echo "PROCC_NAME_$1 is: $PROCC_NAME_$1";
PID_FILE_OF_APP_$1="/run/pidfile_$PROCC_NAME_$1.pid"
PATH_OF_PROCCESS_NAME_$1=`ps -aux|grep $PROCC_NAME_$1|grep -v grep|awk -F" " '{print $12}'`
PID_NUMBER_OF_APP_$1=`ps -aux|grep $PROCC_NAME_$1|grep -v grep|awk -F" " '{print $2}'`
NUMBER_OF_OCCURENCE_$1=`echo ${#PID_NUMBER_OF_APP_$1[@]}`
if [[ "$NUMBER_OF_OCCURENCE_$1" == 0 ]];then
echo -e "Proccess isn't started..nNow process $PATH_OF_PROCCESS_NAME_$1 is running and I'm creating a PID file..."
python /emu/script/$PROCC_NAME_$1.py  & disown & echo $! > $PID_FILE_OF_APP_$1
else
echo "Proccess is STARTRED"
fi
}
chk_is_it_started blabla;

我会得到错误：

root@orangepipc:~# chk_is_it_started blabla;
Could not find the database of available applications, run update-command-not-found as root to fix this
PROCC_NAME_blabla=my_process_blabla: command not found
PROCC_NAME_blabla is: blabla
-bash: PID_FILE_OF_APP_blabla=/run/pidfile_blabla.pid: No such file or directory
Could not find the database of available applications, run update-command-not-found as root to fix this

Could not find the database of available applications, run update-command-not-found as root to fix this
NUMBER_OF_OCCURENCE_blabla=: command not found
Proccess is STARTRED

但事实并非如此！ 我在哪里犯了错误？ 如果我使用没有函数的代码，它可以工作！ 感谢

我找到了解决方案...
