pluckr 0.0.7

Pluck columns from CSV files in the command line. Like cut or awk, but doesn't choke on delimiter escaping.

Latest Version: 0.0.9

Pluck columns from csv files in the commandline. Like cut or awk, but without choking on delimiter escaping.


pip install pluckr. Done.


Grab columns 2 and 3 from stdin (-f is zero-indexed):

pluckr -f 1,2 < sample1.csv

Or straight from a file:

pluckr -f 2,1 sample1.csv

Your requested order is retained:

pluckr -f 1,2 sample1.csv != pluckr -f 2,1 sample1.csv

You can also use Python’s negative indices… grab the first and last cols:

pluckr -f 0,-1 sample1.csv

Can’t be sure which columns exist or what their indices are?

pluckr –names sample1.csv

Fields that don’t exist (e.g. -f11111) will be ignored.

Preprended line numbers can be helpful:

cat sample1.csv | pluckr –line-numbers

Skip header row(s):

cat sample1.csv | pluckr -s1

Grab all but the 2nd column (drop columns instead of selecting them):

pluckr -f 1 -i < sample1.csv

Read (and write) various delimiters:

pluckr -d, –out-delimiter=| < with-commas.csv > with-pipes.csv

Note that passing tabs as arguments can be awkward; in a pinch, use:

pluckr -d $’t’


Via –help:

usage: pluckr [-h] [-f FIELDS] [-i] [-d DELIMITER] [-q QUOTECHAR] [-s SKIP]
[-l] [-n] [infile]

Grab columns from csv input.

positional arguments:
infile input file (.csv)
optional arguments:
-h, --help show this help message and exit
-f FIELDS, --fields FIELDS
 ordered list of columns to retain; zero-indexed
-i, --inverse invert column retention: drop those in -f
 field delimiter when reading infile
 field quotechar when reading infile
-s SKIP, --skip SKIP
 number of rows to skip
-l, --line-numbers
 prepend line numbers to output
-n, --names print column names; assumes one header row


This project uses [roundup]( for testing. Run tests with make test.


  • allow -f to take columns by name when there’s a header row?
  • implement –out-x for output delimiters etc.
  • json output? or, contribute a cli to kennethreitz/tablib
  • add out delimiter support
  • add out quotechar support
