Run Seq
World's simplest linux tool
This online utility implements the Linux command seq. This command prints a sequence of increasing or decreasing numbers. You can customize the starting and ending values, and also the increment step. The numbers can be integers or floating points numbers. If they are floating-point numbers, then you can also adjust their precision. Created by Linux experts from team Browserling.

What is a Run Seq?
learn more about this tool
This JavaScript program runs the Linux seq command in your web browser. The seq command prints an ascending or descending sequence of numbers to the standard output (stdout). As browsers don't really have a stdout, the command prints the sequence to a textbox. The range of the sequence can be specified using the first number (start number) and the last number (end number). The start and end range values can be positive or negative and they can be integers or decimal fractions. The rate at how fast the sequence increases or decreases is controlled by the increment step value. The step can also be a positive, negative, integer, or decimal number. For example, with the options: first value = 5, last value = 10, step = 1, you will get the sequence "5, 6, 7, 8, 9, 10", and with the options: first value = 1, last value = -12, step = -3, you will get the sequence "1, -2, -5, -8, -11". If the first range value is not specified, then it's assigned the default value of 1. If the increment value is not specified, then it's set to 1 (if start < end) or -1 (if start > end). All numbers that fall in the range are displayed on the screen in a vertical column. To print numbers in one line, use the sequence separator option and enter a delimiter character in it, such as a comma, semicolon, or space. We also added a rarely used seq option that lets you equalize the width of the integer part of all printed values. When the "Equal Width" padding option is activated, the program adds several zeros in front of each output value, so that the number of digits in the integer part of all numbers is the same. For example, with this padding option active, the sequence "5, 6, 7, 8, 9, 10" turns into "05, 06, 07, 08, 09, 10". The original Linux seq command also lets you format the output numbers. After reviewing the most common seq use cases, we found that this option is rarely used. The only real use case that we found was controlling the precision of decimal numbers, so we added a precision option to our seq implementation. By specifying a precision value, you make the number of digits after the decimal point equal to the precision value. For example, if you specify the precision to be 3, then the sequence "1.1, 2.2, 3.3, 4.4" becomes "1.100, 2.200, 3.300, 4.400". Tuxabulous!
Run Seq examples
Click to useSequence from 1 to 100
In this example, we're using our browser version of the Linux seq program to create a sequence of integers from 1 to 100. To do this, we set the first number of the sequence to 1, the last number to 100, and the delta increment to 1. We use a space as the sequence element separator and this way get the entire sequence displayed on one line.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100
Required options
First value of the sequence.
Last value of the sequence.
Sequence increment step.
Separate numbers with this
string (default is newline: "\n").
Left-pad numbers with 0s
to make all numbers have
the same width.
Number of digits in the decimal
part of the number.
Equal Width Numbers
In this example, we generate a descending sequence of numbers from 300 to -300 with a negative step value of -50. Since the width of numbers (width is the number of symbols in a number, including the minus sign) varies from 1 to 4 (the number 0 having 1 symbol and the number -100 having four symbols), we use the "Equal Width" option to even out the widths of all numbers. This option adds zero padding to the numbers so that they all become the same length. We print this integer sequence in a vertical column, using the escape sequence "\n" as the value delimiter.

Precision of a Thousandth
This example creates a comma-separated sequence of fractional numbers that fall between -10 and 11 and that have 1.05 units between them. To demonstrate the precision option, we set it to 3, which means rounding the numbers to the thousandths place. Also to make it more fun, we make the length of the integer part equal to the length of the fractional part (both parts are now 3 digits long, including the minus sign).
