How do I pass no arguments to GNU Parallel? Basically, I’d like to loop a command:

parallel --dry-run command_to_repeat ::: `seq 100`

passes the arguments:

command_to_repeat 1
command_to_repeat 2
command_to_repeat 3
command_to_repeat 4
command_to_repeat 5
command_to_repeat 6
command_to_repeat 7
command_to_repeat 8
command_to_repeat 9
command_to_repeat 10
…

But I’d like:

command_to_repeat
command_to_repeat
command_to_repeat
command_to_repeat
command_to_repeat
command_to_repeat
command_to_repeat
command_to_repeat
command_to_repeat
command_to_repeat
…
