Tivosh documentation?

[GriffinW]

I have a vague idea of what tivosh is, but I have searched and searched, and all references to tivosh are discussions between people that already know all about tivosh. Assuming they were not born with the knowledge, where does one go to learn how to use tivosh? I have searched on "tivosh documentation" "tivosh manual" "tivosh tutorial" and various other combinations, but I just get the postings for people who already know how to use tivosh. I am a fairly well versed hacker, just fairly new to tivo. I have hacked one of my Dtivos (series 2) to 4.0.1b and have telnet and ftp access to it.

The reason I am looking for tivosh info is that I want to enable backdoors, and I find references to using tivosh to modify a particular resource to something or other, but no detailed instructions on exactly how to do that. Originally, i just wanted to avoid having to pull out my Tivo drive, and as I can get a shell prompt already, do the change on the Tivo itself. I have read postings that say that is the best way to do that, anyway. But no where can I find the step by step instructions to do that, and, in any case, I like to know what I am doing, so I would like to know at least the basics of tivosh before I jump in.

So, if anybody can point me to a tutorial, manual, or any documentation on tivosh, I would sure appreciate it!

Thanks,

Griffin

So, if anybody can point me to a tutorial, manual, or any documentation on tivosh, I would sure appreciate it!tivosh is a tcl interpreter with extra extensions (commands) loaded that provide tivo functions (accessing the Media File System, MFS, for example). So, as a staring point, goggle for "tcl tutorial" and you should find a lot of hits. tcl is a popular scripting language so there's a lot out there.

As far the tivo extensions, these aren't particularly well documented. Look around on the forums here and elsewhere and you'll probably find some notes. Also, look at the many scripts people have written as examples. There is also tcl code on your tivo in the root file system under /tvlib.

Thanks! I did a google search for 'tcl tutorial', and several came up, so that will get me started. I am sure that I will need to learn some more about this as it applies to Tivo and tivosh, though. I am guessing that those tivo extensions are what I really need to concentrate on, so I'll do some more searching here to see what I can figure out. If anybody has info about those, especailly as it applies to activating backdoors on my 4.01b tivo, without having to pull the hard drive, i would appreciate that. (Altough, for all the time I have spent searching and trying to figure out how to do this, I could have pulled the hard drive and booted off of my Tivo tools CD, and done the hexedit search and replace already!)
