Howdy All! App development question coming...
<TwitchTEK>
What I am looking for:
<TwitchTEK>
An automatic music file organizer.
<TwitchTEK>
Desired endstate
<TwitchTEK>
To have all of my music files, mp3, mp4, ogg, occ, etc... correctly tagged, correctly named, delete all duplicates, and placed in correct folder. I will have a 'one folder to rule them all' music collection on my home server (Windows Server 2008). Folder tree will resemble something along lines of:
<TwitchTEK>
Application needs ability to run in both Linux and Windows environments, and/or, be launched from a Linux environment, browse network to a Windows machine, and execute its actions on files on that Windows machine. Application needs to be 'smart enough' to be pointed to a directory, search every subdirectory, and do its thing; fire and forget. Application needs to correctly tag files automatically,
<TwitchTEK>
correctly rename files automatically, move files and place in correct file/folder/directory structure automatically, and delete duplicates automatically
<TwitchTEK>
Conditions:
<TwitchTEK>
My server, Windows Server 2008 R2 32bit, with a huge chunk of storage as a network shared drive. On this share, I have backups, copies & pastes, and data from hard drives, CDs, and computers from up to about 10 or so years ago. So, in addition to everything else, I have mountains of music spread all over the place.
<TwitchTEK>
What I do not need/want

hey when using File.new||open in a method, is it proper to close the file at the end of said method? Or will it get closed when the program exits? Im basically concerned about open file pointers sticking around.

I'm trying to execute a Ruby script from a bash file which runs via cron. The script executes seemingly fine (as 'root' - not advised etc. etc. I know), however this execution doesn't seem to have loaded the gems correctly as the 'json' gem cannot be found even though it's accessible through regular 'root' ssh usage. I think I need to do something in the bash file to set up the correct Ruby gem path for that session, but I'm not sure..
