Comments on: Averaging text files with bash and awk http://claus.castelodelego.org/archives/539 Claus' little corner on the net Wed, 08 Feb 2012 04:26:42 +0000 http://wordpress.org/?v=2.2.2 By: Claus http://claus.castelodelego.org/archives/539#comment-45212 Claus Mon, 19 Apr 2010 09:35:15 +0000 http://claus.castelodelego.org/archives/539#comment-45212 Oh my. Thanks for the comment Pat! Good thing I did not publish these results yet :-). That's what I get for trying to hammers voodoo recipes without fully understanding them. There is another error in the above code. Calling "$ ./average.sh filename.*" will expand to the first file name, which will average a single file. You need to put "filename.*" in "" in order to prevent it from expanding until it enters the script. Fixing now. Oh my. Thanks for the comment Pat! Good thing I did not publish these results yet :-).

You actually want to pass fld to awk as well (say -v fld="$fld") and then do ta=f+i*fld instead of ta=f. Right now tta is just adding the 'f'th entry s times and dividing it by s, giving back the 'f'th entry. Does finding a bug get bonus points?
