This is a bash script which contains a function used to figure out which assets in a Cinelerra project are not required for the edit list. I created it because I had pulled in a couple of thousand media resources for a project and wanted to eliminate bloat. I moved the project and found it kept crashing on me until I eliminated the crud. I wrote another program to call this function and then actually clean out the xml. You can view “remove_unused_assets.sh” here.

Running this script doesn’t do anything until you call the enclosed function. This function can be called from the command line with:

. list_unused_assets.sh;list_unused_assets
#! /bin/bash
#kk list_unused_assets.sh
#kk
#kk check a cinelerra xml file to see which assets have been loaded, but not used in the project
#kk provide filename to check as parameter
#kk from the command line, type “. list_unused_assets.sh;list_unused_assets “

list_unused_assets()
{

SCRIPTDIR=”$HOME/Video/video_new/common/scripts”
TMPDIR=”/tmp”

. $SCRIPTDIR/include.inc

#location of the temporary files
ASSETS_FILE=”$TMPDIR/ASSETS_FILE”
EDITS_FILE=”$TMPDIR/EDITS_FILE”

#assign the parameter to a variable
XMLFILE=$1

#check if the xml file exists and exit if it does not
if [ ! -e $XMLFILE ]; then error “XML file does not exist”; fi

#if the temp file exists, delete it
if [ -e $ASSETS_FILE ]; then
rm $ASSETS_FILE
fi

if [ -e $EDITS_FILE ]; then
rm $EDITS_FILE
fi

echo
echo Checking $XMLFILE for assets unused by the project…
echo

#find all of the filenames in the xml file and strip the extra junk
grep -E “ASSET SRC=” $XMLFILE | sed -e ‘s/^.*SRC=”//g’ -e ‘s/”>.*$//g’ | sort | uniq > $ASSETS_FILE
grep -E “FILE SRC=” $XMLFILE | sed -e ‘s/^.*SRC=”//g’ -e ‘s/”>.*$//g’ | sort | uniq > $EDITS_FILE

#output the counts
echo `grep -E “ASSET SRC=|FILE SRC=” $XMLFILE | sed -e ‘s/^.*SRC=”//g’ -e ‘s/”>.*$//g’ | sort | uniq | wc -l` Total Assets
echo $RED`comm -23 $ASSETS_FILE $EDITS_FILE | wc -l` Unused Assets$NC
echo $GREEN`comm -12 $ASSETS_FILE $EDITS_FILE | wc -l` Used Assets$NC

}

This program depends on include.inc which contains the following:

#!/bin/bash

#use colour in the output just for fun
GREEN=$(printf “\033[32m”)
RED=$(printf “\033[31m”)
NC=$(printf “\033[0m”)

error()
{
echo ERROR: $1
exit 1
}

I tried to make these scripts as tidy and portable as possible — you will, however, need to change the path for $SCRIPTDIR to the location you are using (and $TMPDIR if you don’t want to put your temporary files in /tmp).
