I couldn't get this letter to osiris!phil. He sent me a run-down on the number of times each song was played. I appreciate the effort, but I've been doing this for a while. Before I get bombarded from all sides, I thought some people might like the scripts that I tried to send to him (I haven't and don't want to figure out ARPA). Here is the letter I tried to get to Phil. Thanks for the info. I have a few nice awk programs to figure out such things. One thing to watch for is when they do "Playin'" twice on one night; it should only be counted once. I use this csh script (fix) to get around that problem: #! /bin/csh -f if ($#argv == 0) then set arg = "" else set arg = "$*" endif awk '\ $0 ~ /[0-9]/ { c = $0 } \ $0 !~ /^[ 0-9a-z]/ { if (NF > 0 && s[$0] != c) { \ print $0 \ s[$0] = c \ } \ }' $arg I also have another useful script called merge: #! /bin/csh -f if ($#argv == 1) then set arg = $argv[1] else set arg = "" endif awk '\ { if (old == $0)\ count++\ else {\ if (count != 0)\ print count, old\ old = $0\ count = 1\ }\ }\ END { print count, old }' $arg A typical sequence is: % fix play* | sort | merge | sort -n These scripts come in handy when I am curious about what mix of songs were played when. I will be writing a program that looks at a set of dates and decides the most number of concerts from those dates that contain no duplicates...funny thing is, it is more or less an assignment in our heuristics class. --Cliff
