Csvtk - Unique Help
-------------------

Info
####

Csvtk unique pulls the first unique values from the column(s) specified to create

.. class:: warningmark

    Single quotes are not allowed in text inputs!

@HELP_INPUT_DATA@


Usage
#####

To run csvtk-uniq, all you need is a valid (as defined above) CSV or TSV and the column(s) that you want the to find unique values in.

**Ex. Unique on one column:**

Suppose you had a table as such

+--------+--------+----------+
| Name   | Colour | Food     |
+========+========+==========+
| Eric   | Blue   | Apples   |
+--------+--------+----------+
| Darian | Blue   | Pancakes |
+--------+--------+----------+
| Daniel | Red    | Apples   |
+--------+--------+----------+
| Frank  | Blue   | Apples   |
+--------+--------+----------+

If you ran csvtk-unique on the Colour column, you would end up with the following table:

+--------+--------+----------+
| Name   | Colour | Food     |
+========+========+==========+
| Eric   | Blue   | Apples   |
+--------+--------+----------+
| Daniel | Red    | Apples   |
+--------+--------+----------+

As only the first instance of the value in the column is kept.

----

**Ex. Unique on more than one column:**

Same input table

+--------+--------+----------+
| Name   | Colour | Food     |
+========+========+==========+
| Eric   | Blue   | Apples   |
+--------+--------+----------+
| Darian | Blue   | Pancakes |
+--------+--------+----------+
| Daniel | Red    | Apples   |
+--------+--------+----------+
| Frank  | Blue   | Apples   |
+--------+--------+----------+

Now if you ran csvtk-unique on the Colour and Food column, you would end up with the following table:

+--------+--------+----------+
| Name   | Colour | Food     |
+========+========+==========+
| Eric   | Blue   | Apples   |
+--------+--------+----------+
| Darian | Blue   | Pancakes |
+--------+--------+----------+
| Daniel | Red    | Apples   |
+--------+--------+----------+

Only the last row was not kept as there was already a unique pair found of "Blue" and "Apples".

**Note:** If you want to only have the unique values of the columns and get rid of the additional columns, run a "cut program" to cut out the wanted columns
and then csvtk unique to only get the wanted values.
