**What it does**

This tool sorts an input file.

-----

**Sorting Styles**

* **Fast Numeric**: sort by numeric values. Handles integer values (e.g. 43, 134) and decimal-point values (e.g. 3.14). *Does not* handle scientific notation (e.g. -2.32e2).
* **General Numeric**: sort by numeric values. Handles all numeric notations (including scientific notation). Slower than *fast numeric*, so use only when necessary.
* **Natural Sort**: Sort in 'natural' order (natural to humans, not to computers). See example below.
* **Alphabetical sort**: Sort in strict alphabetical order. See example below.
* **Human-readable numbers**: Sort human readble numbers (e.g. 1G > 2M > 3K > 400)
* **Random order**: return lines in random order.

------

**Example - Header line**

**Input file** (note first line is a header line, should not be sorted)::

    Fruit   Color   Price
    Banana  Yellow  4.1
    Avocado Green   8.0
    Apple   Red     3.0
    Melon   Green   6.1

**Sorting** by **numeric order** on column **3**, with **header**, will return::

    Fruit   Color   Price
    Apple   Red     3.0
    Banana  Yellow  4.1
    Melon   Green   6.1
    Avocado Green   8.0


-----

**Example - Natural vs. Alphabetical sorting**

Given the following list::

    chr4
    chr13
    chr1
    chr10
    chr20
    chr2

**Alphabetical sort** would produce the following sorted list::

    chr1
    chr10
    chr13
    chr2
    chr20
    chr4

**Natural Sort** would produce the following sorted list::

    chr1
    chr2
    chr4
    chr10
    chr13
    chr20


.. class:: infomark

If you're planning to use the file with another tool that expected sorted files (such as *join*), you should use the **Alphabetical sort**,  not the **Natural Sort**. Natural sort order is easier for humans, but is unnatural for computer programs.
