This article mainly introduces the use of the seq command in Linux, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

The Linux common command seq command is used to generate all integers from one number to another.

Seq prints numbers from the first to the Mantissa in specified increments

Syntax seq [options]... Mantissa seq [option]... The first and last seq [option]. The first increment Mantissa option-f,-- format= format uses the printf-style floating-point format-s,-- separator= string uses the specified string to separate numbers (default:\ n)-w,-- equal-width adds 0 before the column to make the width the same instance-f option: specify format

# seq-f the number of digits specified after "% 3G" 9 11 9 10 11% defaults to% gjournal% 3G, then the number of digits below is a space.

# sed-f "g" 9 11 # seq-f "strg" 9 11 str009 str010 str011 if the number of digits is insufficient, the number of digits is 0% before setting the string.

-w option: specifies that the output number is the same width

Seq-w 98 101 098 099 100 101 cannot be used with-f, the output is the same width.

-s option: specify the delimiter (enter by default)

Seq-s ""-f "strg" 9 11 str009 str010 str011 to specify / t as the separator:

Seq-s "`echo-e" / t "`" 9 11 specifies\ nas the separator:

Seq-s "`echo-e"\ n "`" 911 19293949596979899910911 is an error, but it is generally not necessary. It defaults to enter as the delimiter.
