In the last five lessons you wrote scripts for the budget, the resource group, permissions and policies. The same few moves kept coming up:
--query, --output tsv, $LASTEXITCODE, -WhatIf. This lesson gathers them, explains them thoroughly and adds two tools: Resource Graph,
which lets you query all resources at once, and a way to test scripts without any Azure at all. At the end there are two new scripts in the
repository: one finds Kladde resources without an owner tag, the other adds it.
Output formats
Every Azure CLI command knows --output (-o for short) with these values:
| Format | What it’s for |
|---|---|
json |
The default. Complete, long for humans, ideal for programs, for example with ConvertFrom-Json. |
jsonc |
JSON with colors, only for reading in the terminal. |
yaml, yamlc |
YAML, without and with colors. |
table |
A table for reading. |
tsv |
Values separated by tabs, without quotation marks, one line per result. For scripts. |
none |
No output, only the exit code. For commands that change something and whose answer you don’t need. |
The table has a catch: it leaves out fields like id, type and etag and writes column names like name as Name. If you want particular
columns, give them names of your own with --query, as the scripts in this module do.
