(I use it as a ROX-Filer app, but it can also work via CLI.) I can drag-and-drop a text file onto the program's icon. The file specifies a 'mode' and a pid per line, and the program then proceeds to chug though them as I make breakfast. If needed, the file I give it could also say if any particular reprocessing need be done 'now' or left to later, etc. So I'd almost certainly do this via a 'C' approach because I've become used to 'C' over the years. The trick is knowing what commands to launch, etc. Modifying where output goes, making the output -raw, etc, is OK as I know how to do that - once I've sorted out unknowns like if the -raw is going to ramdisc or somewhere else, when reprocessing is done, etc. Thus, yes, I am thinking it should be possible to do this via running 'one program'. But... Truth is, having finally allowed people to prise FORTRAN out of my cold dead hands a decade or more ago, I'm now settled on 'C'. :-) Jim -- Electronics https://www.st-andrews.ac.uk/~www_pa/Scots_Guide/intro/electron.htm Armstrong Audio http://www.audiomisc.co.uk/Armstrong/armstrong.html biog http://jcgl.orpheusweb.co.uk/history/ups_and_downs.html Audio Misc http://www.audiomisc.co.uk/index.html _______________________________________________ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer
