I was searching a lot for some Regular expression for iTerm Triggers   There are the ones i found so far: MAC-Address ([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2}) IPv6 ([0-9A-Fa-f]{1,4}:([0-9A-Fa-f]{1,4}:([0-9A-Fa-f]{1,4}:([0-9A-Fa-f]{1,4}:([0-9A-Fa-f]{1,4}:[0-9A-Fa-f]{0,4}|:[0-9A-Fa-f]{1,4})?|(:[0-9A-Fa-f]{1,4}){0,2})|(:[0-9A-Fa-f]{1,4}){0,3})|(:[0-9A-Fa-f]{1,4}){0,4})|:(:[0-9A-Fa-f]{1,4}){0,5})((:[0-9A-Fa-f]{1,4}){2}|:(25[0-5]|(2[0-4]|1[0-9]|[1-9])?[0-9])(\.(25[0-5]|(2[0-4]|1[0-9]|[1-9])?[0-9])){3})|(([0-9A-Fa-f]{1,4}:){1,6}|:):[0-9A-Fa-f]{0,4}|([0-9A-Fa-f]{1,4}:){7}: IPv4 \b(?:[0-9]{1,3}\.){3}[0-9]{1,3}\b I will keep that up2date
