mpeg toc maker

I got tired of having Cinelerra hang while create table of contents files for a list MPEG videos. So I wrote my own script to create the table of contents files for a list of MPEGs in a directory. Once you specify the LIST, the script plops the table of contents files in your users' .bcast directory in ~/.bcast.

I output the file name, start time, end time and elapsed time for the table of contents creation. This output looks like this:

SCRIPTSTART:                  20100130_121201

*** Update 2010/05/28 ***
I added a little logic to the beginning of the script that checks for the presence of a single argument to the script. That argument is the name of a single file to convert. So now, you have two choices:
1) convert a list of mpeg files as specified in the LIST variable or
2) convert a single file via the command line like so:
./tocMaker.sh videoToConvert.m2t
*** end update ***

Here is the script:

#!/bin/bash
#
# tocMaker.sh
# Author: SCF
# Website: http://crazedmuleproductions.blogspot.com
#
# Purpose: This script builds the table of contents files for a list of mpeg files
#
# Input: List of mpeg files as specified in the LIST variable or a single file via command line like so:
#  ./tocMaker.sh videoToConvert.m2t
#
# Output: Runs mpeg3toc and puts toc's in your users' .bcast directory
#
DEBUG=
if [ $1 ]
then
 LIST=$1
else
 LIST="*.m2t"
fi
echo "converting $LIST"
TOTALTIME=0
function dt {
       DATE=$(date +"%Y%m%d_%H%M%S")
       echo $DATE
}
function st {
       SECONDS=$(date +%s)
       echo $SECONDS
}
PWD=$(pwd)
DIR=$(echo $PWD | sed 's/\//_/g' | sed 's/^_//g')

SCRIPTSTART=$(dt)
printf "%13s %32s\n" "SCRIPTSTART:" $SCRIPTSTART

for FILE in $(ls -1 $LIST)
do
       START=$(dt)
       COUNTBEGIN=$(st)
       NEWFILE=$(echo $FILE | sed 's/\./_/g')
       FULLPATH="${DIR}_${NEWFILE}.toc"
       ORIG_PATH="$PWD/$FILE"
       if [ $DEBUG ]
       then
               echo "$FILE was: $FILE, is: $NEWFILE"
               echo "FULLPATH is $FULLPATH"
               echo "command is mpeg3toc $ORIG_PATH ~/.bcast/$FULLPATH"
       fi
       mpeg3toc $ORIG_PATH ~/.bcast/$FULLPATH
       END=$(dt)
       COUNTFINISH=$(st)
       ELAPSED=$(expr $COUNTFINISH - $COUNTBEGIN)
       printf "%13s %32s %11s %15s %11s %15s %11s %7d\n" "FILE:" $FILE "START:" $START "END:" $END "TIME(s):" $ELAPSED
       TOTALTIME=$(expr $ELAPSED + $TOTALTIME)
done
SCRIPTEND=$(dt)
printf "%13s %32s %11s %15d\n" "SCRIPTEND:" $SCRIPTEND "RUNTIME(s):" $TOTALTIME
