一个简单但是实用的小shell脚本

近日调试程序，因为CGP的服务器要求复制更新文件后需要重启才能使文件生效，所以每次更新文件都需要手工重启一下CGP服务器，甚是麻烦，所以使用几个简单的命令，写了个shell，用着挺省心，贴上源码：

#!/bin/sh

#define path to be watched
SPY_PATH=/var/CommuniGate/Domains/ruyi.com/WebSkins

#create file tap.lst and initial it
if [ -f "tpa.lst" ]; then
 echo -n ""
else
 echo "---" > tpa.lst
fi

#loop and pause serveral seconds
while [ 1=1 ]; do
line=
ls -ltr --time-style=full-iso  $SPY_PATH | grep -E ".wss|.js" > tp.lst
tail -n1  tp.lst > tpo.lst
line=$(cmp tpo.lst tpa.lst)
if [ -n "$line" ];
then
  rm -f tpa.lst
  cp  tpo.lst tpa.lst
  #restart CGP Server (stop then start), the command can be replaced with other commands you need
  /etc/init.d/CommuniGate stop
 
  /etc/init.d/CommuniGate start
  echo ""
  echo -n "=========================================="
  echo $(date +"%F %X")
else
 echo -n ""
fi
#echo -n "loop....."

sleep 3
done
exit 0
