conplot - console plotter via ascii art Brendan O'Connor - brenocon@gmail.com - http://github.com/brendano/conplot conplot is a script for when you have a file or stream of lots of numbers and want to look at it fast. Needs many more features, but basics work. Usage: pipe a column of numbers on stdin to conplot.rb. Tries to be smart about other junk in the file. It is intended to work with shell tools like perl -pe, awk/sed, wc, du, sort|uniq -c and the like. Example: time.log is a big list of numbers from a (while sleep 1; do du -m db; done) loop. I want to know how fast the db is growing over time. $ wc -l time.log 77879 time.log $ head -2 time.log 35 db 36 db $ tail -2 time.log 14540 db 14540 db $ cat time.log | conplot 14601 oooooooo oooooo ooooooooo oooooooooooo 11269 oooooooo oooo ooo oooo oo ooo 7271 ooooo oooo oooo oooo oooo oooo 3272 oo o o oo ooo ooo -726 0 76826 Features to do, that probably will never get done * scatterplots!!! x,y as two columns on stdin. almost already supported. * size according to terminal size (e.g. look at stty -a) * histograms should be integrated as an option -- or, use github.com/stevej/conhist
