My first open source programs

Have been writing many toy programs which end up in the recycle bin, and then flush to no place. I hope from now onwards, my programs can have longer livespan. Let me start with some bash scripts, xman utility under GPL:

• xman_rm: Move given files into the folder ".deleted". So that I can recover the files in the future if we need to.
• xman_list_rb: List files deleted using xman_rm.
• xman_clean_rb: Delete all files found by xman_list_rb permanently.
• xman_create_pdfdb: Process given folder recursively for .pdf files. Convert all .pdf files into .txt and store in database folder.
• xman_lowercase: Convert all given file names to lowercase.
• xman_uppercase: Convert all given file names to uppercase.
• xman_chext: Convert file extension to another extension.
• xman_tolower_filter: Convert strings from stdin to lowercase.
• xman_toupper_filter: Convert strings from stdin to uppercase.

Hope these scripts may help you for your work. If not, you may still learn some bash scripts from these. :) You may also suggest useful scripts for routine work.
