This is a utility built into just about EVERY Unix/Linux system out there, and it’s probably available for Windows in some form also. I had some issues using tv_cat with TVHeadEnd, and wound up using a small quick-and-dirty shell script to combine XMLTV listings files instead (see below). tv_cat is a bit picky about the format of the files it will combine, so check the output carefully to make sure it is including all the channels. This program may already be on your backend system but if it’s not, you can typically install it on a Ubuntu/Debian-based system (and possibly in some other Linux distros) by installing the xmltv package. The man page description says, “Read one or more XMLTV files and write a file to standard ouput whose programmes are the concatenation of the programmes in the input files, and whose channels are the union of the channels in the input files.” Or in simple terms, it merges XMLTV format files together. tv_cat – Concatenate XMLTV listings files.Note that you will probably need to use the full path and filename if you are attempting to run the program from a shell script or a cron job! If the program is installed on your system, it should show you the path to the file.
NOTE: To find out if you have a particular program installed on your system, try entering the word which followed by a space and the program name at a Linux command prompt. These are in addition to zap2xml and zap2epg, which I mentioned in my previous article. Here are a few tools that run under Linux that I have found that may be useful, under certain circumstances. So let’s say you have one or more XMLTV type files, but you want to do some additional manipulation on them before feeding them to your backend software. In my previous article, Some hints for getting free-to-air satellite channels into the Electronic Program Guide in Kodi or XBMC (or another frontend), I mentioned that schedule “grabber” programs save their files in XMLTV File format.
