It’s weird with a multi-command string (i.e. when semicolons get involved), shortest answer is to fiddle with it. I think it may work at the beginning if you put the rest of the command in a (subshell)?

Pro tip: you can also put the < urls.txt at the start for readability. The arrow doesn’t have to point at the command.
