Mike, thank you!

Chris, did the script I emailed you solve the problem you were having with the script?

Yes, Marc, thanks! The script you e-mailed worked just fine. Sorry it took so long to respond. I also see that the script earlier in this thread has been edited so that it is correct.

So I guess the remaining question is why myth tv doesn't recognize the old recordings properly. ie: Why it doesn't count them as part of the max # of recordings you can keep.

I'm not sure I can help you with that one, but I would suggest making sure the permissions and ownership on those files is the same as all of the others.

Hi,
It sounds like cmaines hosed himself with the restore button if I read the thread correctly? The nuv files are still valid to play however because of the restore function, the matching label in the database is gone. I think I referred to that as a C or D situation? The trick would be is to figure out how to recreate manually a name in the data base that refers to the orphaned recording.

A possible way of doing that, would be to make a junk recording, then using webmin I suppose one could go into db under the recordings and edit the file names to reference the orphans. It would have to be real important for that kind of effort :)

Thanks
Mike

I have BEEN less then successful with this script or any script for mythlink.sh.

I have carefully read this entire thread.. to no avail...

When I run this manually I get lots of errors.. See Snippet blow:

Use of uninitialized value in concatenation (.) or string at -e line 23, <> line 2.
Use of uninitialized value in concatenation (.) or string at -e line 23, <> line 2.
Use of uninitialized value in pattern match (m//) at -e line 37, <> line 2.
Use of uninitialized value in substr at -e line 40, <> line 2.
substr outside of string at -e line 40, <> line 2.
Use of uninitialized value in hash element at -e line 40, <> line 2.

substr outside of string at -e line 40, <> line 2.
Use of uninitialized value in concatenation (.) or string at -e line 40, <> line 2.

---- End of snippet ----

2nd it creates these erronous files in /myth/tv/

root@mythtv:~# ls /myth/tv
'rehash' to get table and field completion, but startup__.nuv
--disable-auto-rehash.__.nuv
Directory where character sets are.__.nuv
No automatic rehashing. One has to use 'rehash' to get__.nuv
Set the default character set.__.nuv
and reconnecting may take a longer time. Disable with__.nuv

Any ideas?

Hi linuxgeek,

Not sure which script you ran, however one thing to be very watchful of is line wrapping. It helps if when you start your nano add the -w switch. nano -w <your-script-label-here>

That is often the cause for things not seeming to work properly. Marc did a great job on the task and it does work (assuming we talking to same script for mythlink.sh) :)

I wasn't able to find the thread however it was connected to "deadwood"

Thanks Marc..

I have my mysql passwd protected for root.

So I added the -p PASSWD to the mysql run line.

This was breaking mythlink.sh.

Thanks to Marc for pointing out the space issue
between -p and PASSWD... Once I removed the
space all is well now...

Thanks Marc and Mjl for your posts.

Folks:

Below is an updated version of the "dead_wood" script. The key change is that I've added a way of providing a password for those that have password protected their MYSQL data bases. I don't have password protection on my MYSQL data base and I am able to confirm it works properly with no password. Linuxgeek has confirmed that it works properly on his password-protected MYSQL data base -- thanks to Linuxgeek for running that test for me!

Marc

Code:
#! /bin/bash
#
# This scropt will look for orphased ".nuv" files in /myth/tv
# directory and delete them. It will also check the data base
# for references to non-existant ".nuv" files, and create a
# dummy ".nuv" file where necessary. To protect your system
# from "run away" deletions, this script uses the following
# logic:
#
# 1. It will not do anything to a "nuv" file that is referenced in the
#    "recorded shows" listing of the myth data base.
# 2. It will not do anything to a "nuv" file that is less than 2 hours old.
# 3. If it detects more than 8 "nuv" files that appear to be orphaned,
#    it will exit without taking any action.
# 4. Files that pass the previous 3 tests are not deleted. Instead they are
#    moved to the directory /myth/tv/TRASH. If they remain untouched in this
#    directory for 7 days, then they are automatically deleted.
#
#
TV="/myth/tv"
TRASH=$TV/TRASH
AGE="7"
MAX=8
PASSWORD=""
#
# Verify existance of input directories
#
if [ ! -e "$TV" ]
then
    echo "$TV does not exist -- script halted."
    exit 1
fi
mkdir -p $TRASH
if [ ! -e "$TRASH" ]
then
    echo "Unable to created directory $TRASH"
    exit 1
fi
if [ "$PASSWORD" == "" ]
then
    PASS=""
else
    PASS="-p$PASSWORD"
fi
#
# Create a list of files that exist in $TV that aren't in the DB
#    and a list of files that exist in the DB that aren't in $TV.

After reading this thread I think the Deadwood script should work for me. Here is my problem -
I have deleted several shows from the MythTV Interface and the shows do not show up in the listings. I went to the pretty dir several days later and the shows I deleted were still there, so I just deleted them. 30 minutes later Mythlink kicks in and the shows popup again as 1 byte files. Found this thread with Deadwood. Ran the Deadwood script and no joy. I looked in the new trash folder and there is nothing in there and the 1 byte files are still listed in Pretty and TV. Tried again after 24 hours to take in account the 1 day delay and I am still having no progress. So my question is the Deadwood script the one I should be running for this problem?

Thanks

I am working with RCS via email to figure out what is happening, but in the meantime, a problem has come to light.

Earlier in this thread it was suggested that people both run the "deadwood" script and add the following lines to "mythlink.sh":

Code:
ls -Li /myth/pretty/*.mpg | sort > /tmp/mpg-files
ls -Li /myth/tv/*.nuv | sort > /tmp/nuv-files
join -v 2 /tmp/mpg-files /tmp/nuv-files | cut -d " " -f 2 > /tmp/dead-files
cat /tmp/dead-files | sed -e "s/^/rm -f /" > /tmp/rm-dead-files


If you added those lines to mythlink.sh I suggest you remove them. They will interfear with the deadwood script and they are not necessary, as "deadwood" will take all the necessary actions. Thanks.

Marc
