User Guide - Add command example standardisation

Note from the teaching team: This bug was reported during the Part II (Evaluating Documents) stage of the PE. You may reject this bug if it is not related to the quality of documentation.

Add command example for task tk/ sometimes contain space and sometimes the lack of space. Although both command works both ways, would be better to standardise and show only the same kind of example.

This is important to specify due to find command having compulsory space between prefix and value to work properly.
