G'day,

Is there anything that will delete these files?
Code:
drwxr-xr-x 2 root   root     4096 Mar 24 00:02 2012-03-21
drwxr-xr-x 2 root   root     4096 Mar 25 00:02 2012-03-22
drwxr-xr-x 2 root   root     4096 Mar 28 00:02 2012-03-23
drwxr-xr-x 2 root   root     4096 Mar 28 00:02 2012-03-24
drwxr-xr-x 2 root   root     4096 Mar 28 00:02 2012-03-25
drwxr-xr-x 2 root   root     4096 Mar 29 00:02 2012-03-26
drwxr-xr-x 2 root   root     4096 Mar 27 00:08 2012-03-27
drwxr-xr-x 2 root   root     4096 Mar 28 13:08 2012-03-28

Those are directories containing your myth related log data, divided up by day. I think its actually a pretty clever way to keep the logs more readable. They should get automatically logrotated out before they become a problem, so you can delete them, but you don't have to delete them.

Does anyone understand how the file names are created? My log files start with the name of the computer and end with what appears to be a random number. I am sure there is some system to this but I cant figure out which backend log follows which.

the number is the pid of the process

Code:
[mythtv@mythtv log]$ cd 2012-08-27
[mythtv@mythtv 2012-08-27]$ ls -la
total 216
drwxr-xr-x  2 root root  4096 Aug 27 08:08 .
drwxr-xr-x 18 root root  4096 Aug 27 03:11 ..

-rw-r--r--  1 root root  1111 Aug 27 10:20 mythtv_su.log
[mythtv@mythtv 2012-08-27]$ ps -ef | grep 31808
mythtv   11859   734  0 18:25 pts/2    00:00:00 grep 31808
mythtv   31808 31776  0 03:11 ?        00:00:34 /usr/bin/mythbackend -q --syslog local6
[mythtv@mythtv 2012-08-27]$ ps -ef | grep 5300
mythtv   11867   734  0 18:26 pts/2    00:00:00 grep 5300
[mythtv@mythtv 2012-08-27]$ ps -ef | grep 26664
mythtv   11878   734  0 18:26 pts/2    00:00:00 grep 26664
[mythtv@mythtv 2012-08-27]$ ps -ef | grep 2151
mythtv    2151  2006  0 Aug11 ?        02:29:31 /usr/bin/mythfrontend -d --syslog local6
mythtv   11888   734  0 18:26 pts/2    00:00:00 grep 2151


in the above example, there are two backend logs. one with a pid of 5300 and the other with a pid of 31808. the pid 5300 probably no longer exists because of my 3 am backup cronjob

Seems like it might make more sense to put the time or some sequential number in the file name rather then the PID. With only the PID in the file name, its not easy to follow from one log to the next.

doing it by pid is a mythtv "feature", it was done to make debugging easier..but in practice it's just a mess.

You're not kidding!!!

At least the log files do have the full time stamp for each entry though. So it should be straight forward for some clever script writer to create a myth log viewer. Probably just a reassembly based on time stamp which you can pipe into your favourite editor or less/more.
