Python script execution Shell, execute Python script via crontab
| The code is as follows |
Copy Code |
| #!/usr/bin /env python
#-*-coding:utf-8-*- Import OS
Import time
Import datetime
Import subprocess Tod Ay =datetime.date.today ()
Deltadays = Datetime.timedelta (Days=1) #确定日期差额, such as the day before yesterday days=2
Yesterday = today-deltadays Month = yesterday.strftime ('%b ')
date = Yesterday.strftime ('%d ') Command1 = "Ls-hl/log1 | grep '%s ' | awk ' {print i$9} ' i= '/log1/' | Xargs RM "% (month, date)
Command11 =" Ls-hl/log1 | grep '%s %s ' | awk ' {print i$9} ' i= '/log1/' | Xargs RM "% (month, date)
Command2 =" Ls-hl/log2 | grep '%s ' | awk ' {print i$9} ' i= '/log2/' | Xargs RM "% (month, date)
Command22 =" Ls-hl/log2 | grep '%s %s ' | awk ' {print i$9} ' i= '/log2/' | Xargs rm% (month, date) Os.system (Command1)
Os.system (command11)
Os.system (Command2)
Os.system ( COMMAND22) |
Attention
| The code is as follows |
Copy Code |
ls-hl/log2 | grep '%s ' | awk ' {print i$9} ' i= '/log2/' | Xargs RM
|
This shell command is best done through Python execution shell promise to look at the specific file listed in the format to prevent invalid
| The code is as follows |
Copy Code |
Print Os.system ("ls-hl/log2")
|
The result can be obtained after running. And then modify it according to the specific circumstances.
Example 2, the day before the deletion date.
| The code is as follows |
Copy Code |
Import datetime
Import time def get_yestoday (mytime):
Myday = datetime.datetime (int (mytime[0:4)), int (mytime[4:6]), int (mytime[6:8))
#now = Datetime.datetime.now ()
Delta = Datetime.timedelta (days=-1)
My_yestoday = myday + Delta
My_yes_time = My_yestoday.strftime ('%y%m%d ')
Return My_yes_time |
example, delete files within a specified time within a folder
| The code is as follows |
Copy Code |
| #-*-coding=gbk-*-
Import OS
Import time def listdir (Filedir):
For Eachfile in Os.listdir (filedir):
If Os.path.isfile (filedir+ "/" +eachfile): #如果是文件, to determine the last modified time, match the conditions for deletion

The last modification time of the "+path+"/"+eachfile+" of the #print "+str" (ltime);
ntime = Int (Time.time ()) -3600*3; #获取现在时间减去3h
If Ltime<=ntime:
Print "I want to delete the file" +filedir+ "/" +eachfile;
