renamejpg.sh: to rename all prefix of jpg files in the given directory. I usually use a prefix of filename as a "tag" to search as important keyword. So instead of "IMG_xxx.jpg", it is more meaningful to name it as "Keyword_xxx.jpg"

mp3-to-mp4-to-youtube.sh: to convert mp3 files to mp4 (using a random image) and upload these files to Youtube. The dhamma talks by Ajahn Martin on Youtube generated from this script can be found under Dhamma FromForest.
