http://visidata.org/ http://visidata.org/ is a nice one for quickly getting an overview of some tabular data – you can even just stick it at the end of your pipe. If bzcat foo.bz2|sort|uniq -c|sort -nr | awk -f munge.awk |blah produces a tsv, then bzcat foo.bz2|sort|uniq -c|sort -nr | awk -f munge.awk |blah|vd makes that tsv an interactive (if you think ncurses is interactive) spreadsheet with plotting and pivot tables and mouse support :) You can also save your keypresses in vd to a file and then re-run them at a later stage – I've got some scripts to re-run an analysis and then run vd on it and immediately set all columns to floats and open the frequency table so I can see if I managed to lower the median this time.
