Is there a way to combine columns from cli output?-CodePudding

I want to get memorydb endpoint URL in the format (address:port). When I run the aws cli command aws memorydb describe-clusters --cluster-name xxx --query 'Clusters[0].ClusterEndpoint' --output text, I get the output as (address port).

I want to get it in the format (address:port). Is there a command i can use to add ':' to combine address and port number.

Thanks

Possible to achieve this by using simple sed, something like this:

aws memorydb describe-clusters --cluster-name xxx --query 'Clusters[0].ClusterEndpoint' --output text | sed 's/ /:/g'

See if this works! I haven't tested it with aws cli.

Assuming you have set your variable to the string which you posted, i.e.

x='(address port)'

you can calculate

y=${x/ /:}

which gives you on y the value (address:port).
