thanks, appreciate the help Steve:
I am at work at present and will try your suggestions when i get home
tonight; however, does this seem to make sense.

Two scripts  1) has the ' *find <directory> -iname '*.ts' -type f -execdir
/path/to/script.sh "{}" \;*'  data and calls script.sh.
                     2) script.sh

can i modify script.sh to include multiple '*then*' statements?
e.g.

script.sh
#! /bin/bash
if [ ! -e lock ];
then touch lock;
if ffmpeg -y -i "$1" -vf scale=-1:720 -c:v libx264 -crf 23 -preset
ultrafast -c:a copy $(basename "$i" .ts) "$i.mp4";
*then*
* ccextractor "$x" -o "$y".srt  *
then
rm "$1";
fi

is this likely to be a solution that will scan entire multimedia hdd (if i
put in correct path by find statement) and then ffmpeg the .ts to .mp4 then
extract closed caption info, then remove the .ts files?
