请教大家个问题：
我想写这样的判断，如果comid 在（5100,1200,3302,3400,3600,4500）这个集合里面。if这一段代码还没有比较简洁的写法，谢谢。
comid=$1
if [[ ${comid} == '5100' ]] || [[ ${comid} == '1200' ]] || [[ ${comid} == '3302' ]] || [[ ${comid} == '3400' ]] || [[ ${comid} == '3600' ]] || [[ ${comid} == '4500' ]]
then
echo " #######";
else
echo "$$$$$$$$$$$$$$$$$"
fi

文本test.txt里面包含这些数字,每行一个数字
AA=`grep $comid test.txt`
if [ -z "$AA" ]
then
echo long is zero
else
echo the No. is in
fi收起
AA=`grep $comid test.txt`
if [ -z "$AA" ]
then
echo long is zero

可以通过嵌套循环语句实现。收起
