jot(1) is a shell command from BSD that can print a list of numbers. jot(1) is convenient when a UNIX Shell program needs to iterate a range of numbers. Examples that use jot(1) will not work with other Unix systems that are missing jot(1).
<lang bash># Example: this loop echoes Got 1, Got 2, Got 3. for i in `jot 3`; do echo Got $i done</lang>
The syntax is jot count begin end step
All four arguments are optional. A hyphen - skips an argument. Here are some examples.
