**What it does**

This tool runs the **cut** unix command, which extract or delete columns from a file.

-----

Field List Example:

**1,3,7** - Cut specific fields/characters.

**3-**    - Cut from the third field/character to the end of the line.

**2-5**   - Cut from the second to the fifth field/character.

**-8**    - Cut from the first to the eight field/characters.


Input Example::

    fruit	color	price	weight
    apple	red	1.4	0.5
    orange	orange	1.5	0.3
    banana	yellow	0.9	0.3


Output Example ( **Keeping fields 1,3,4** )::

    fruit	price	weight
    apple	1.4	0.5
    orange	1.5	0.3
    banana	0.9	0.3

Output Example ( **Discarding field 2** )::

    fruit	price	weight
    apple	1.4	0.5
    orange	1.5	0.3
    banana	0.9	0.3

Output Example ( **Keeping 3 characters** )::

    fru
    app
    ora
    ban
