I often use the jenkins cli as part of my jenkins management workflow. There is one
subcommand I always want to use but then I remember that it is horrible to work with
jenkins-cli console. This command is grabs the build logs of a specified pipeline
and presents them in your terminals stdout. There are two issues I have with
this subcommand. One, the encoding is wonky so I will often try and awk a
specific subset of the logs to no avail. Second, it only gets one build log at a time
and you have to reference that build by its build id, aka an incrementing number
no one is keeping track of so you have to open up the gui and check the run
anyways which defeats the purpose.
So I made a simple cli tool with more verbose options to grab build logs from
jenkins that you can actually pipe a grep too without losing what little hair
you probably have left since your probably managing a jenkins instances. Enjoy
