I have the temp monitor file going fine per this thread
ads-b-flight-tracking-f21/temperature-limitations-on-the-equipment-t26939-25.html
What I would like to do is take the temperature file created in var/log (var/log/tempcheck.log) and append it to tempcheck.log.yesterday and then have a new one made to dump
the temp information into it.
Similar to the piaware log
thanks
What about doing:
$ sudo pico /etc/logrotate.d/temp-check
In that file paste in:
/var/log/tempcheck.log {
daily
rotate 4
copytruncate
}
Change the “4” to the number of days you want to keep the logs. It will only hold 4 days (+ the current days log being created).
I think that will do. I’m sure someone will speak up otherwise.
set it for a 2 day rotate … Ill see what it does 
Thanks
Hmm Getting an error and I think its permissions
-bash: /var/log/tempcheck.log: Permission denied
Not sure which CHMOD setting to use.
Give a fish answer: chmod a+x
Teach fishing answer: man chmod
A log file shouldn’t need executable permissions. I would instead check what the owning UID/GID are, and what the overall permissions are.
The file its self is in /Var/Log … I was trying to just append it each day …
Owner is Root
-rw-rw-r-x 1 root root 3550 Jul 5 22:17 tempcheck.log
Where the error is, its when I log in its supposed to give me the temp of the rig (which it is) but just before that it gives me this error
-bash: /var/log/tempcheck.log: Permission denied
Its all per the above link.
what is the user that is running the temperature logging program.
can you sudo tempcheck > logfile maybe?
I log in as pi …
-rwxr-xr-x 1 root staff 166 Jul 1 08:10 tempcheck
when I do sudo tempcheck > Testfile
It gives
sudo tempcheck > testfile
-bash: testfile: Permission denied
Apparently pi doesn’t have -bash permissions.
On the good side. The job is working found these in my /var/log directory today
tempcheck.log
tempcheck.log.1
see if it fills up tempcheck.log
