Here is a regular expression (regex) pattern that can be used to find GraphQL queries or mutations in a file:

```regex
/\b(query|mutation)\b[\s\S]*?\{[\s\S]*?\}/g
```

This pattern uses word boundaries (\b) to ensure that only complete words "query" or "mutation" are matched, and it uses a non-greedy wildcard match ([\s\S]*?) to capture the entire query or mutation block, including the curly braces. The g flag at the end of the pattern enables global matching, which allows multiple queries or mutations to be matched within the same file.

This is a basic pattern that can be customized to match the specific syntax of your GraphQL queries or mutations, if necessary.<|im_end|>

```javascript
const file = `query {
  getUsers {
    name
    age
  }
}

mutation {
  addUser(name: "John", age: 32) {
    name
    age
  }
}`

const regex = /(query|mutation)\s*\{\s*[\w\s\(\)\:\,]+\s*\}/g
const matches = file.match(regex)

console.log(matches)
// Output: [ 'query {\n  getUsers {\n    name\n    age\n  }\n}', 'mutation {\n  addUser(name: "John", age: 32) {\n    name\n    age\n  }\n}' ]
```

In this example using JavaScript, the variable file holds the text to be searched for GraphQL queries or mutations. The regex variable holds the regular expression described above. The match() method is called on the file variable, passing in the regex variable as an argument. The result of this call is an array of all matches found in the file text. In this case, the output will show two matches, one for the query and one for the mutation.<|im_end|>
