Three indispensable REGEX hacks
summary
Three practical regex techniques and a working pattern for the example file set are given: use ^ and $ as anchors to force full-string matches, use grouping and alternation like \.(csv|ods) to match extensions literally (escape the dot), and use character classes with quantifiers like [A-Za-z] to allow any mixed-case name. Concrete pattern for files starting with project and an underscore or dash is ^[Pp]roject[_-][A-Za-z]*\.(csv|ods)$ which matches only project_foo.csv or project-bar.
