			0

			8
			10

			==Zero-Padding==

			Sometimes it's useful to have a fixed-width number, with zero-padding. That's why seq offers the -w (for width) option:

			<source>
			$ seq -w 0 2 10
			00
			02
			04
			06
			08
			10
			</source>

			==Complex String Formatting==

			You can use the -f flag to format your string using printf functionality.

			To print a 4-digit integer, with zero padding, you'll use the <code>%04g</code> printf sequence:

			<source>
			$ seq -f'%04g' 0 2 10
			0000
			0002
			0004
			0006
			0008
			0010
			</source>

			To print a 4-digit integer with spaces for padding, you can use the <code>%4g</code> printf sequence:

			<source>
			$ seq -f'%4g' 0 2 10
			0
			2
			4
			6
			8
			10
			</source>

			To print the sequence of numbers with a prefix, you can add a prefix to the printf sequence, e.g.:

			<source>
			$ seq -f'_%04g' 0 2 10
			_0000
			_0002
			_0004
			_0006
			_0008
			_0010
	</source>		</source>

New page

The seq command can be used for creating numerical sequences of numbers.

=Basic Use of Seq=

If you want a list of numbers from 1 to 10:

<source>
$ seq 1 10
1
2
3
4
5
6
7
8
9
10
</source>

or, if you want a backwards list:

<source>
$ seq 10 1
10
9
8
7
6
5
4
3
2
1
</source>

==Custom Increment==

If you want a sequence of numbers from A to B with a particular increment i, feed three arguments to seq: <code>seq A i B</code>

<source>
$ seq 0 5 50
0
5
10
15
20
25
30
35
40
45
50
</source>

You can also give negative increments,

<source>
$ seq 50 -5 0
50
45
40
35
30
25
20
15
10
5
0
</source>
