嵌入式初學(xué)者，第一次上傳代碼。昨天做了一個(gè)udhcpd與udhcpc的守護(hù)，目前只會(huì)用shell模仿編寫(xiě)，還有什么方法可以做守護(hù)呢？

#! /bin/sh#進(jìn)程名字可修改PRO_NAME=udhcpcWLAN=ra0 while true ; do #    用ps獲取$PRO_NAME進(jìn)程數(shù)量  NUM=`ps aux | grep ${PRO_NAME} | grep -v grep |wc -l`#  echo $NUM#    少于1，重啟進(jìn)程  if [ "${NUM}" -lt "1" ];then    echo "${PRO_NAME} was killed"    ${PRO_NAME} -i ${WLAN}#    大于1，殺掉所有進(jìn)程，重啟  elif [ "${NUM}" -gt "1" ];then    echo "more than 1 ${PRO_NAME},killall ${PRO_NAME}"    killall -9 $PRO_NAME    ${PRO_NAME} -i ${WLAN}  fi#    kill僵尸進(jìn)程  NUM_STAT=`ps aux | grep ${PRO_NAME} | grep T | grep -v grep | wc -l`   if [ "${NUM_STAT}" -gt "0" ];then    killall -9 ${PRO_NAME}    ${PRO_NAME} -i ${WLAN}  fidone exit 0

以上所述就是本文的全部?jī)?nèi)容了，希望能夠?qū)Υ蠹沂煜inux shell腳本有所幫助。
