               [FILE]
Search CSV files. Like the Unix "grep" command, but for tabular data.
positional arguments:


  FILE                  The CSV file to operate on. If omitted, will accept


                        input on STDIN.
optional arguments:


  -h, --help            show this help message and exit


  -n, --names           Display column names and indices from the input CSV


                        and exit.


  -c COLUMNS, --columns COLUMNS


                        A comma separated list of column indices or names to


                        be searched.


  -m PATTERN, --match PATTERN


                        The string to search for.


  -r REGEX, --regex REGEX


                        If specified, must be followed by a regular expression


                        which will be tested against the specified columns.


  -f MATCHFILE, --file MATCHFILE


                        If specified, must be the path to a file. For each


                        tested row, if any line in the file (stripped of line


                        separators) is an exact match for the cell value, the


                        row will pass.


  -i, --invert-match    If specified, select non-matching instead of matching


                        rows.
