Official CLI tools make it much easier to build automation with shell scripts.

One example that comes to mind - we used hub to hack together a quick security feature that errors out our CI/CD pipeline (which runs shell scripts) if there are any open PRs that are labeled "security" (i.e. Dependabot opening a PR to update a vulnerable library), which forces developers to keep their dependencies up-to-date in order to deploy into production.

GUI tools don't work as part of CI/CD pipelines.

Libraries in higher-level languages (e.g. Python) force you to make sure that there's a library for every tool that you work with - if a specific tool is missing a Python library, then you have to deal with that yourself. Shell scripting is much more productive for gluing multiple sets of tooling together, as long as the shell scripts remain of a maintainable length.
