DESCRIPTION

usage: csvgrep [-h] [-d DELIMITER] [-t] [-q QUOTECHAR] [-u {0,1,2,3}] [-b]

[-p ESCAPECHAR] [-z FIELD_SIZE_LIMIT] [-e ENCODING] [-S] [-H] [-K SKIP_LINES] [-v] [-l] [--zero] [-V] [-n] [-c COLUMNS] [-m PATTERN] [-r REGEX] [-f MATCHFILE] [-i] [-a] [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 as piped data via STDIN.

optional arguments:

-h, --help

show this help message and exit

-d DELIMITER, --delimiter DELIMITER

Delimiting character of the input CSV file.

-t, --tabs

Specify that the input CSV file is delimited with tabs. Overrides "-d".

-q QUOTECHAR, --quotechar QUOTECHAR

Character used to quote strings in the input CSV file.

-u {0,1,2,3}, --quoting {0,1,2,3}

Quoting style used in the input CSV file. 0 = Quote Minimal, 1 = Quote All, 2 = Quote Non-numeric, 3 = Quote None.

-b, --no-doublequote

Whether or not double quotes are doubled in the input CSV file.

-p ESCAPECHAR, --escapechar ESCAPECHAR

Character used to escape the delimiter if --quoting 3 ("Quote None") is specified and to escape the QUOTECHAR if --no-doublequote is specified.

-z FIELD_SIZE_LIMIT, --maxfieldsize FIELD_SIZE_LIMIT

Maximum length of a single field in the input CSV file.

-e ENCODING, --encoding ENCODING

Specify the encoding of the input CSV file.

-S, --skipinitialspace

Ignore whitespace immediately following the delimiter.

-H, --no-header-row

Specify that the input CSV file has no header row. Will create default headers (a,b,c,...).

-K SKIP_LINES, --skip-lines SKIP_LINES

Specify the number of initial lines to skip before the header row (e.g. comments, copyright notices, empty rows).

-v, --verbose

Print detailed tracebacks when errors occur.

-l, --linenumbers

Insert a column of line numbers at the front of the output. Useful when piping to grep or as a simple primary key.

--zero

When interpreting or displaying column numbers, use zero-based numbering instead of the default 1-based numbering.

-V, --version

Display version information 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, names or ranges to be searched, e.g. "1,id,3-5".

-m PATTERN, --match PATTERN

A string to search for.

-r REGEX, --regex REGEX

A regular expression to match.

-f MATCHFILE, --file MATCHFILE

A path to a file. For each row, if any line in the file (stripped of line separators) is an exact match of the cell value, the row matches.

-i, --invert-match

Select non-matching rows, instead of matching rows.

-a, --any-match

Select rows in which any column matches, instead of all columns.
