Print a sequence from 1 to 10:

seq 10

Print a sequence from 10 to 20:

seq 10 20

Print every 3rd number from 5 to 20:

seq 5 3 20

Separate the output with a space instead of a newline:

seq {{[-s|--separator]}} " " {{5 3 20}}

Format output width to a minimum of 4 digits padding with zeros as necessary:
