sedcsv
NAME
sedcsv – stream editor functionality for filtering and editing
columns in .csv files
SYNOPSIS
Usage: sedcsv [-d|-V] [-E] [-l] [-n] [OTHEROPTIONS] -f SCRIPTFILE DATAFILE
DESCRIPTION
Sedcsv allows a small subset of sed(1) operations to be performed
on a .csv file, where actions (including patterns) are applied to
specific columns in the "target" .csv file. The patterns themselves
are also taken from a .csv file. Patterns in columns in the script
file may be related to columns in the data file by column number or by
column name.
