csvcut

Filter and truncate CSV files. Like Unix's cut command, but for tabular data. Included in csvkit.

Print indices and names of all columns:

csvcut -n {{data.csv}}

Extract the first and third columns:

csvcut -c {{1,3}} {{data.csv}}

Extract all columns except the fourth one:

csvcut -C {{4}} {{data.csv}}

Extract the columns named "id" and "first name" (in that order):

csvcut -c {{id,"first name"}} {{data.csv}}
