Displaying CSV files in a readable way on the terminal

 Until this week I did not know about the column command.

$ head -5 zillow.csv
"Index", "Living Space (sq ft)", "Beds", "Baths", "Zip", "Year", "List Price ($)"
 1, 2222, 3, 3.5, 32312, 1981, 250000
 2, 1628, 3, 2,   32308, 2009, 185000
 3, 3824, 5, 4,   32312, 1954, 399000
 4, 1137, 3, 2,   32309, 1993, 150000

Turned out this file is much more readable with a good pipe (and a large screen)

$ head -5 zillow.csv | column --table --separator ,
"Index"   "Living Space (sq ft)"   "Beds"   "Baths"   "Zip"     "Year"   "List Price ($)"
 1        2222                     3        3.5       32312     1981     250000
 2        1628                     3        2           32308   2009     185000
 3        3824                     5        4           32312   1954     399000
 4        1137                     3        2           32309   1993     150000

column is part of util-linux and is thus available in all distributions.
