#!/bin/bash
#Shell
# #根据修改文件时间进行监控 # #
C-l/tmp/log.txt | awk ' {print $} '//Get file size
Filetime= ' stat/tmp/q | Tail-1 | awk ' {print $2,$3} '//Get file update time
test= ' cat/tmp/log.txt '//view file contents
if [$content = = "0"];then//If the file size is 0
echo $filetime >/tmp/log.txt
elif ["$filetime" = = "$test"];then//If the file is not modified then execute
Killall Nginx
/home/nginx_server/nginx/sbin/nginx
else//If you modified the execution to write the time that the file was modified to log
echo $filetime >/tmp/log.txt
