Hey folks. I could use some help with a (bash) script, trying to check for deleted files.
Problem background:
I have an extensive video library on disk. All legaly recorded from television with mythtv. I wrote a script to generate an XML file from that library, contaning info on all video files with file size, duration, audio languages, audio- & videocodecs, bitrates, etc.
To update this XML file, the script currently just throws the old version away and generates a new XML file from scratch, iterating through all directories and all files again, and probably only a couple have changed.
Having only very little programing experience, the best I could come up with a little help of google was the idea to:
- Loop through all files with find, put the output of find into an array, store the array into a "storagefile". This file would document all files in the XML at the first run. Then proceed as normal with the first run, generate the XML file.
- For the next run, only files newer than the date of the first run would need to be added to the XML.
- However old files, that are now deleted would have to be removed from the XML file. To do so, I would reload the "storagefile" into an array, loop through that array and check if the files are still present on disk. I case a file was in the array, but no longer on disk, it's <video> ... </video> entry would need to be removed from the XML file.
This however sounds rather complicated to me. Am I missing something? Are there easier options for what I want? Does anyone have some code sniplets for similiar problems, and wants to share with me?
Thanks in advance for any pointers,
best regards
