<m:pre jazyk="bash"><![CDATA[relpipe-in-cli \

		--relation "relation_from_cli" \

			--attribute "a" "integer" \

			--attribute "b" "string" \

			--attribute "c" "boolean" \

			--record "1" "Hello" "true" \

			--record "2" "World!" "false"]]></m:pre>

			For now, we will use the „tabular“ format and pipe relational data to the <code>relpipe-out-tabular</code>.

		<m:pre jazyk="bash"><![CDATA[relpipe-in-cli \

		--relation "relation_from_cli" \

			--attribute "a" "integer" \

			--attribute "b" "string" \

			--attribute "c" "boolean" \

			--record "1" "Hello" "true" \

			--record "2" "World!" "false" \

			The syntax is simple as we see above. We specify the name of the relation

			and the names and types of attributes

		<m:pre jazyk="bash"><![CDATA[(relpipe-in-cli --relation "a" --attribute "x" string --record "hello"; \

 relpipe-in-cli --relation "b" --attribute "y" string --record "world") \

		<p>

			In the example above, we call <code>relpipe-in-cli</code> twice and let the shell combine their outputs.

			This approach is useful when we want to combine relational data from various sources: different <code>relpipe-in-*</code> tools, files etc.

			But when we work with <code>relpipe-in-cli</code> only, we can ask it to create several relations during one run:

		</p>

		<m:pre jazyk="bash"><![CDATA[relpipe-in-cli \

		--relation "a" --attribute "x" string --record "hello" \

		--relation "b" --attribute "y" string --record "world" \

	| relpipe-out-tabular]]></m:pre>

		<p>

			The result will be the same.

			We can also use the <code>--records</code> option instead of the <code>--record</code> option – then the rest of the CLI arguments is treated as data of given relation.

			Obviously this option can be used only once for the last relation.

		</p>

		<m:pre jazyk="bash"><![CDATA[relpipe-in-cli \

		--relation "relation_from_cli" \

			--attribute "a" "integer" \

			--attribute "b" "string" \

			--attribute "c" "boolean" \

			--records \

				"1" "Hello" "true" \

				"2" "World!" "false" \

	| relpipe-out-tabular]]></m:pre>

		<p>

			It will generate the same <code>relation_from_cli</code> table as above.

			If we have more data (especially from external sources), we can use the <code>--records-on-stdin</code> option and pass them through the <m:a href="examples-cli-stdin">STDIN</m:a>.
