Matches (MATCHES) string operator
The Matches (MATCHES) string operator will return true if the left string operand will match the regular expression that is in the right string operand.
If the right string operand is not a valid regular expression, the result will be empty.
The regular expression syntax follow rust regex - see details in Rust regex docs.
For example:
findit -w 'name matches "^a[a-z]+\\.rs"'
Will display only the files with name that follow the pattern ^a[a-z]+\\.rs.
