You only have one "variable" in sed, which is called the "hold space". You can copy or append the current "pattern space" to the "hold space", or you can exchange the two, but inserting the contents of one in the middle of the other is difficult.

You would do much better with awk or perl or similar.

canto-fetch

Canto-fetch(1)							    Canto-fetch 						    Canto-fetch(1)

NAME

       Canto-fetch - A quiet feed fetcher.

DESCRIPTION

       Canto-fetch  is	designed  to  be run through a cron job, every minute. Every time it's run, it checks the timestamp on each index file and
       updates the feed, if necessary. The format it produces is a simple UTF-8 encoded, NULL delimited text file on disk, readable by	the  canto
       client.

GETTING STARTED

       Canto-fetch is meant to be used through a cron, adding this line to your crontab will cause canto-fetch to poll every minute.

       * * * * * canto-fetch

       Alternatively,  if  you're unable/uncomfortable using cron, canto-fetch has a background daemon mode so you can invoke it in your X session
       scripts. Just use

       canto-fetch -b

USAGE

       These options correspond to options to the canto client.

       -h / --help
	      Print usage and quit.

       -v / --version
	      Print version and quit.

       -V / --verbose
	      Output status while updating.

       -d / --daemon
	      Continue to check for updates every minute. Mostly for debugging with -V, users probably want -b to background.

       -b / --background
	      Detach from the terminal (implies -d)

       -f / --force
	      Force updates on all feeds, ignoring timestamps.

       -s / --sysfp
	      Use feedparser on system instead of builtin copy.

       -C / --conf [PATH]
	      Set path to configuration file (default: ~/.canto/conf)

       -F / --fdir [PATH]
	      Set path to feed directory (default: ~/.canto/feeds/)

       -L / --log [PATH]
	      Set path to log (default: ~/.canto/fetchlog)

       -S / --sdir [PATH]
	      Set the path to execurl scripts (default ~/.canto/scripts/)

FILES

       ~/.canto/fetchlog
	      Canto-fetch log file.

       ~/.canto/feeds/
	      This is the directory where canto-fetch records stories.

BUGS

       None known, but it's not outside of the realm of possibility =P.
