检查数组是否包含bash中的字符串

我制作了一个简单的bash脚本,以根据合并请求的源分支更改数字版本,如果某个功能或hotfix/bigfix/fix分支名称:

#!/bin/bash

if [  $# -eq 0 ]
then
    echo -e "\nUsage: $0 MERGE_REQUEST_SOURCE\n"
    exit 1
fi

if [ ! -f version ]; then
    echo "0.0.0" > version
fi

VERSION=$(cat version)
MERGE_REQUEST_SOURCE=$1
declare -a FEATURE_LIST=("feature")
declare -a HOTFIX_LIST=("fix" "hotfix" "bugfix")

IFS="."
read -a num <<< ${VERSION}
MAJOR=${num[0]}
FEATURE=${num[1]}
HOTFIX=${num[2]}

if [[ ${MERGE_REQUEST_SOURCE} =~ .*${FEATURE_LIST[*]}.* ]]; then
    FEATURE=$((${FEATURE}+1))
    echo "${MAJOR}.${FEATURE}.${HOTFIX}" > version
elif [[ ${MERGE_REQUEST_SOURCE} =~ .*${HOTFIX_LIST[*]}.* ]]; then
    HOTFIX=$((${HOTFIX}+1))
    echo "${MAJOR}.${FEATURE}.${HOTFIX}" > version
else
    echo -e "Nothing change, exit."
    exit 0
fi

FEATURE_LIST 只包含 feature 工作,如果我打字的话 ./script.sh feature ./script.sh feature/foobar 如果我键入 ./script.sh hotfix HOTFIX_LIST 什么都没发生。哪里出错了?
