Script to find VIDEO_TS.IFO and create an ISO

frater · 07-13-2008, 01:01 PM

I would like to write a cronjob that will parse the tree of a download directory for the file "VIDEO_TS.IFO" and if it finds one it should make an ISO out of it written to a specific directory.
Sometimes the directory in which VIDEO_TS.IFO resides is called VIDEO_TS (which is valid) but sometimes it's the name of the DVD. The name of the ISO should be <dvdname>.ISO

The file structure could be like this.

/downloaddir/DVD/Some Like it Hot/VIDEO_TS/VIDEO_TS.IFO
/downloaddir/How to Marry a Millionaire/VIDEO_TS.IFO

In the end I want:

/DVD/Some Like it Hot.ISO
/DVD/How to Marry a Millionaire.ISO

and my original files deleted.

Can someone point me into the right direction, so I can make a decent cronjob out if it?

My problem is in getting the automated process right with the appropriate checks. the mkisofs command itself is the least of my problem. It should also check if the files are not being written to at the time the cronjob is running.

possibly something like this?

Code:

#!/bin/bash

for ifo_file in /downloaddir/DVD/*/VIDEO_TS/VIDEO_TS.IFO
do
	mkisofs $ifo_file && rm $ifo_file ## blah, i dont know the syntax to convert ifo to iso
done

for ifo_file in /downloaddir/*/VIDEO_TS.IFO
do
	mkisofs $ifo_file && rm $ifo_file ## blah, dont know syntax for mkisofs
done

mv /downloaddir/DVD/*/VIDEO_TS/*.ISO /downloaddir/
mv /downloaddir/*/*.ISO /downloaddir/
rm -Rf /downloaddir/DVD/*
mv /downloaddir/*.ISO /downloaddir/DVD/

As far as checking for the files being written to.... the only thing i can think of is to check for the process that downloads them... to see if its running....

Then you could put something like this right at the start:

Code:

if [ `ps aux | awk '{print $11}' | grep PROCESS` ]
	then exit 0
fi

Substituting PROCESS for whatever process actually downloads....

I would carefully test this bad boy though. :-P My scripting is TERRIBLE.

BTW, a great resource for scripting is : http://www.tldp.org/LDP/abs/html/

Hi,

Thanks....
I just peeked in here to see if somebody replied.
However.. In the mean time I think I created my script, so I will post it here..
Maybe someone can make a comment...
About testing if it is being written to, I was thinking about lsof.

But probably it isn't necessary at all. The script that's putting it there has already completed all filewriting and puts it there using a "mv"

#!/bin/sh

DVD_PATH=/shares/internal/PUBLIC/DVD

if [ -z "$1" ] ; then
DOWNLOAD_PATH=/shares/internal/PUBLIC/Torrent/NZB/usenet
else
DOWNLOAD_PATH="`dirname $1`/`basename $1`"
fi

if [ ! -d "$DOWNLOAD_PATH" ]; then
echo "The directory $DOWNLOAD_PATH does not exist!"
exit
fi

#
#
find $DOWNLOAD_PATH -name VIDEO_TS.IFO |
while read f ; do

TS_DIR=`dirname "$f"`

cd "$TS_DIR"

if [ -f "../VIDEO_TS/VIDEO_TS.IFO" ]; then
cd ..
else
mkdir VIDEO_TS
mv * VIDEO_TS
fi
if [ ! -d "AUDIO_TS" ]; then
mkdir AUDIO_TS
fi

thisdir=`pwd`
isofile="$DVD_PATH/${thisdir##/*/}.ISO"

if [ ! -f "$isofile" ]; then
mkisofs -dvd-video -o "$isofile" .
else
echo "$isofile already exists"
fi
done

Looks more impressive than mine, thats for sure

I changed the script some more. Besides creating ISO's it now also looks for ISO's.
It also cleans up the name of the files.
If someone knows how to improve it I'm interested.

logger -s "The directory $DOWNLOAD_PATH does not exist!"
exit
