# File Operators
|
|
|
|
File operators are most often used with merge when needing to merge specific files together. Note that when doing this, you will need to use `eval-all` to ensure all yaml documents are loaded into memory before performing the merge (as opposed to `eval` which runs the expression once per document).
|
|
|
|
Note that the `fileIndex` operator has a short alias of `fi`.

## Merging files
|
|
Note the use of eval-all to ensure all documents are loaded into memory.
|
|
```bash
|
|
yq eval-all 'select(fi == 0) * select(filename == "file2.yaml")' file1.yaml file2.yaml
|
|
```
