<h2>cut - Cut out selected fields of each line of a file</h2>

<strong>Synopsis</strong>
|
|
|
|
<p><strong>cut -b</strong> <em>list</em> [<em>file ...</em>]</p>
|
|
|
|
<p><strong>cut -c</strong> <em>list</em> [<em>file ...</em>]</p>
|
|
|
|
<p><strong>cut -f</strong> <em>list</em> <strong>[-d</strong> <em>
|
|
string</em><strong>] [-s]</strong> [<em>file</em> ...]</p>
|
|
|
|
<p><strong>Description</strong></p>
|
|
|
|
<p>The <strong>cut</strong> utility selects portions of each line
|
|
as specified by <em>list</em> from each <em>file</em> (or the
|
|
standard input by default), and writes them to the standard output.
|
|
The items specified by <em>list</em> can be in terms of column
|
|
position or in terms of fields delimited by a special character.
|
|
Column numbering starts from 1.</p>
|
|
|
|
<p>The <em>list</em> is a comma or whitespace separated set of
|
|
increasing numbers and/or number ranges. Number ranges consist of a
|
|
number, a dash (-), and a second number and select the fields or
|
|
columns from the first number to the second, inclusive. Numbers or
|
|
number ranges may be preceded by a dash, which selects all fields
|
|
or columns from 1 to the first number. Numbers or number ranges may
|
|
be followed by a dash, which selects all fields or columns from the
|
|
last number to the end of the line. Numbers and number ranges may
|
|
be repeated, overlapping, and in any order. It is not an error to
|
|
select fields or columns not present in the input line.</p>
