shell 取反实现

使用场景：有很多任务，要能实现执行其中一个任务，也要能实现执行这个任务的其余任务

我开始用数组实现的版本：
如果前缀是！表示取反

array=(MingXingLian XmxcdjX guanfang myFastAPP myFeiYung myLingyw myXiZang myXinJ myYuePai myYuesou mybuluo myfenxiang mymv mymydj mywozuiniu myyueting myzhyx mydzbfq)

function del_array {
for (( i = 0 ; i < ${#array[@]} ; i++ ))
do
if [ "$1" == "${array[$i]}" ] ;then
del_array_index $i
break
fi
done
}

function del_array_index {
array=(${array[@]:0:$1} ${array[@]:$(($1 + 1))})
}

product=$１

if [  ${product} ] && [ ${product:0:1} = "!" ]; then
 product="${product:1}"
 del_array $product
elif [ ${product} ]; then
  array=(${product[@]})
 fi

echo " final product is ${array[@]}"

修改后直接在使用场景判断的版本：

array=(MingXingLian XmxcdjX guanfang myFastAPP myFeiYung myLingyw myXiZang myXinJ myYuePai myYuesou mybuluo myfenxiang mymv mymydj mywozuiniu myyueting myzhyx mydzbfq)

product=$１
reverse=$２

for one in ${array[@]}
do
    if [ ${reverse} ]; then

        if [  ${product} = ${one} ]; then
            continue
        fi
    elif [  ${product} != ${one} ]; then
             continue
    fi
＃具体的实现的地方
done
