Linux系统上面使用python切割nginx日志

#!/usr/bin/python  

  
import time  
import os 
import commands 
  
path = [‘/var/log/Nginx/‘,‘access.log‘] 
(num,Nginxpid_str) = commands.getstatusoutput("/usr/bin/ps aux|grep Nginx|grep Nginx|awk ‘/master/{print$2}‘")
Nginxpid=int(Nginxpid_str.split("\n")[0])
yesterday = commands.getoutput(‘date -d "yesterday" +%Y%m%d‘)  
new_path=‘/var/log/new/‘
target="%saccess_%s.log" % (new_path,yesterday)
command_main = "cd %s && /bin/mv   %s %s && /bin/kill -USR1 %d " % (path[0],path[1],new_path,Nginxpid)
command_tar = "cd %s && /bin/tar  czvf  %s.tar.gz %s && rm -f %s%s" % (path[0],target,path[1])  
command_del = "/usr/bin/find %s -type f -mtime +11 -exec rm -f {} \;" % (new_path)

(status,outtt)=commands.getstatusoutput(command_main)
print(status,outtt)

if status == 0:
    print("successs")
    (tar_status,tar_out)=commands.getstatusoutput(command_tar)
        if tar_status == 0:
        print("tar---ok")
        (del_status,del_out)= commands.getstatusoutput(command_del)
else:
    print("failure")
