       Execute a SQL-like join to merge CSV files on a specified column or columns.

   positional arguments:
       FILE   The CSV files to operate on. If only one is specified, it will be copied to STDOUT.

   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.

       -L LOCALE, --locale LOCALE
              Specify the locale (en_US) of any formatted numbers.

       -S, --skipinitialspace
              Ignore whitespace immediately following the delimiter.

       --blanks
              Do not convert "", "na", "n/a", "none", "null", "." to NULL.

       --date-format DATE_FORMAT
              Specify a strptime date format string like "%m/%d/%Y".

       --datetime-format DATETIME_FORMAT
              Specify a strptime datetime format string like "%m/%d/%Y %I:%M %p".

       -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 (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.

       -c COLUMNS, --columns COLUMNS
              The column name(s) on which to join. Should be either one name (or  index)  or  a  comma-separated
              list  with one name (or index) for each file, in the same order that the files were specified. May
              also be left unspecified, in which  case  the  two  files  will  be  joined  sequentially  without
              performing any matching.

       --outer
              Perform a full outer join, rather than the default inner join.

       --left Perform a left outer join, rather than the default inner join. If more than two files are provided
              this will be executed as a sequence of left outer joins, starting at the left.

       --right
              Perform  a  right  outer  join,  rather  than  the  default inner join. If more than two files are
              provided this will be executed as a sequence of right outer joins, starting at the right.

       -y SNIFF_LIMIT, --snifflimit SNIFF_LIMIT
              Limit CSV dialect sniffing to the specified number of  bytes.  Specify  "0"  to  disable  sniffing
              entirely.

       -I, --no-inference
              Disable type inference when parsing CSV input.

       Note that the join operation requires reading all files into memory. Don't try this on very large files.
