How to import multiple ip's to Ipset?

I am using iptables with ipset on an Ubuntu server firewall. I am wondering if there is a command for importing a file containg a list of ip's to ipset. To populate an ipset, right now, I am adding each ip with this command: ipset add manual-blacklist x.x.x.x It would be very helpfull if I can add multiple ip's with a single command, like importing a file or so. At command for ip in cat /home/paul/ips.txt; do ipset add manual-blacklist $ip;done I get this response resolving to IPv4 address failed to parse 46.225.38.155 for each ip in ips.txt I do not know how to apply it.
