Print a sequence of numbers to standard output
SYNTAX seq [OPTION]... [FIRST [STEP]] LAST... OPTIONS `-f FORMAT' `--format=FORMAT' Print all numbers using FORMAT; default `%g'. FORMAT must contain exactly one of the standarding float output formats `%e', `%f', or `%g'. `-s STRING' `--separator=STRING' Separate numbers with STRING; default is a newline. The output always terminates with a newline. `-w' `--equal-width' Print all numbers with the same width, by padding with leading zeroes. (To have other kinds of padding, use `--format').
`seq' prints the numbers from FIRST to LAST by STEP.
By default, FIRST and STEP are both 1, and each number is printed on its own line. All numbers can be reals, not just integers.
"Quality in a product or service is not what the supplier puts in. It is what the customer gets out and is willing to pay for. A product is not quality because it is hard to make and costs a lot of money, as manufacturers typically believe. This is incompetence. Customers pay only for what is of use to them and gives them value. Nothing else constitutes quality." - Peter Drucker
