FDS_REGISTRAR_ADDRESS=$(echo $DEPLOYMENT_OUTPUT | grep -Po 'FDSRegistrar deployed to: \K[^\s]*')

this command throw an error on mac os

Info from stackoverflow

grep -P enables PCRE syntax. (This is a non-standard extension -- not even all builds of GNU grep support it, as it depends on the optional libpcre library, and whether to link this in is a compile-time option).

It would be great to replace it with some params that supported on mac os.

Please triage for urgency @nugaon .

Please add your planning poker estimate with ZenHub @nugaon

[nugaon]

it is not that urgent as this should be built by the github ci which uses Linux.

since I don't have mac to try out the mac solution, maybe @IgorShadurin could address this issue and find the solution that works on OSX as well.

[IgorShadurin]

To extract the contract address from the DEPLOYMENT_OUTPUT variable on Mac and Ubuntu, use the awk command. This solution uses awk to match lines with the FDSRegistrar deployed to: string and prints the fourth field, which should be the contract address. Here's an example:

FDS_REGISTRAR_ADDRESS=$(echo $DEPLOYMENT_OUTPUT | awk '/FDSRegistrar deployed to:/ {print $4}')

But it should be tester with real data
