How to list all files in ". ts" format of folders and subfolders to be converted to ". avi"?

Question

I found a shell-script and modified it to meet my need and stayed like this:

#!/bin/bash
[ "$1" ] && cd "$1"

ls -1 *.TS
[ "$?" -ne 0 ] && echo 'Sem arquivos TS nesse diretório' && exit 0
for ARQUIVO in $(ls -1 *.TS)
do
ARQ_DESTINO="${ARQUIVO%%.TS}.avi"
echo "Convertendo $ARQUIVO para $ARQ_DESTINO"

ffmpeg -i "$ARQUIVO" -vcodec libxvid -b 2000k \
-acodec libmp3lame -ac 2 -ar 44100 -ab 128k "$ARQ_DESTINO"
done

Only I don’t know how to make this script enter the subdirectories and take each file .ts and convert to .avi, in this case up there it only does in the directory in which the script is.

How can I do with this script to do this process?

Answer 1

Perhaps it would be more appropriate to use the find for this task:

find . -name "*.TS" | while read -r ARQUIVO; do
  ARQ_DESTINO="${ARQUIVO%%.TS}.avi"
  echo "Convertendo $ARQUIVO para $ARQ_DESTINO"
  #....   
done

The point . indicates the current directory, the search starts from it.
