give variable as name

[kozm]

i'm struggling with my first python script, please help me if you can.
it is an infinite loop, that runs a program. the program with the command - sudo ~/hdd -r(report function) /my/cloud/folder - creates a report file about the condition of the hdd. (I'm using an old hdd to backup my cloud so the report file will be automatically uploaded to the cloud, this way i can check is the hdd still reliable or not.) I would like to name the report txt file with the date, when it was written.

act = datetime.date.today()
while True:
os.system("sudo ~/hdd -r /my/cloud/folder/act.txt") #this is a command that runs the program which writes the file!

time.sleep(14400)

act = datetime.date.today() < will be inside the loop

You need to create the file "act.txt" then write the date/time data to it.
Do a bit of googling about python and files, you'll find loads of examples.

I think you can do it like this:

Code: Select all

while True:
    act = datetime.date.today() 
    os.system("sudo ~/hdd -r /my/cloud/folder/" + act + ".txt") 

    time.sleep(14400)

Try

os.system("sudo ~/hdd -r /my/cloud/folder/" + act + ".txt")

Or if act isn't a string str(act)

What a horribly complex way to do it.

Why not use a /etc/cron.daily script?

sudo nano /etc/cron.daily/hdd

Code: Select all

#!/bin/bash
DATE=$(date +%d-%m-%y)
/home/pi/hdd -r "/my/cloud/folder/"$DATE".txt"

sudo chmod 755 /etc/cron.daily/hdd
sudo /etc/init.d/cron reload
