Shell 时间与时间戳相换（Mac）

一、时间戳转时间 timestamp2date.sh

#!/bin/sh

function usage(){
    echo "-h --help \n" \
         "  将10/13位时间戳转换为本地时间 \n"\
         "  参数：时间戳，支持10/13位两种 \n"\
         "  默认值：当前时间向后5min \n"\
         "  e.g. 1483430400(10位秒时间戳),1483430400000(13位毫秒时间戳) \n"
    exit 1
}

###
os_platform=`uname -s`
if [[ $# -le 0 ]]; then
    echo "默认按照当前时间向后5min取值"
    if [[ "${os_platform}" = "Darwin" ]];then
        echo `date -v+5M +"%Y-%m-%d %H:%M:%S"`
    elif [[ "${os_platform}" = "Linux" ]];then
        echo `date -d +5min +"%Y-%m-%d %H:%M:%S"`
    fi
else
    case $1 in
      -h|--help)
          usage
      ;;
      *)
          timestampStr=${1}
          length=`echo ${#timestampStr}`
          if [[ ${length} -ne 10 ]] && [[ ${length} -ne 13 ]];then
              echo "请输入10/13位数字时间戳"
              exit 1
          elif [[ ${length} -eq 13 ]];then
              timestampStr=${timestampStr:0:10}
          fi
          echo "时间戳位：${timestampStr}"
      if [[ "${os_platform}" = "Darwin" ]];then
              dateStr=`date -r${timestampStr} +"%Y-%m-%d %H:%M:%S"`
          elif [[ "${os_platform}" = "Linux" ]];then
              dateStr=`date -d @${timestampStr} +"%Y-%m-%d %H:%M:%S"`
          fi
          echo "${1}对应的本地时间为${dateStr}"
      ;;
    esac
fi

命令行执行

sh timestamp2date.sh 1507704300000
时间戳位：1507704300
1507704300000对应的本地时间为2017-10-11 14:45:00

二、时间转时间戳 date2timestamp.sh

#!/bin/sh

function usage(){
    echo "-h --help \n" \
         "  将本地时间转换为13位时间戳(毫秒时间戳) \n"\
         "  只有1个参数:本地时间，参数格式：'%Y-%m-%d %H:%M:%S' \n"\
         "  默认值：当前时间向后5min \n"\
         "  e.g. 2017-01-01 16:00:00 \n"
    exit 1
}


##时间采用正则匹配
time_pattern="^[0-9]{4}-[0-9]{1,2}-[0-9]{1,2} [0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2}"
os_platform=`uname -s`

if [[ $# -le 0 ]]; then
    echo "默认按照当前时间向后5min取值"
    if [[ "${os_platform}" = "Darwin" ]];then
        echo `date -v+5M +%s`000
    elif [[ "${os_platform}" = "Linux" ]];then
        echo `date -d +5min +%s`000
    fi
else
    case $1 in
      -h|--help)
          usage
      ;;
      *)
          dateStr=${1}
          echo ${dateStr}
          if [[ "${dateStr}" =~ ${time_pattern} ]];then
              if [[ "${os_platform}" = "Darwin" ]];then
                  echo `date -j -f "%Y-%m-%d %H:%M:%S" "${dateStr}" +%s`000
              elif [[ "${os_platform}" = "Linux" ]];then
                  echo `date -d "${dateStr}" +%s`000
              fi
          else
              echo "时间格式不正确，请按照'%Y-%m-%d %H:%M:%S'格式输入，如'2017-01-01 16:00:00' "
          fi
      ;;
    esac
fi

命令行执行

sh date2timestamp.sh '2017-10-13 14:38:30'
2017-10-13 14:38:30
1507876710000
