### Merging Coverage Files with Multiple Glob Patterns (bash)

Source: https://github.com/baryshevrs/nyc-merge/blob/main/README.md

This command shows how to merge coverage reports from different directories. It uses two glob patterns to find `coverage-final.json` files under both the `coverage` and `test-coverage` directories and combines them into `merged-coverage.json`. Requires nyc-merge to be installed and runnable.

```bash
nyc-merge --out merged-coverage.json "coverage/**/coverage-final.json" "test-coverage/**/coverage-final.json"
```

Source: https://github.com/baryshevrs/nyc-merge/blob/main/README.md

This command demonstrates how to use nyc-merge to find and merge all files named `coverage-final.json` located within any subdirectories under the `coverage` folder, saving the result to `merged-coverage.json`. Requires nyc-merge to be installed and runnable.

```bash
nyc-merge --out merged-coverage.json "coverage/**/coverage-final.json"

### Using nyc-merge Command Line Syntax (bash)

Source: https://github.com/baryshevrs/nyc-merge/blob/main/README.md

This snippet shows the general command-line syntax for running the nyc-merge tool. It requires the `--out` option to specify the output file and one or more glob patterns to find input coverage files. The `--concurrency` option is optional.

```bash
nyc-merge --out <output.json> [--concurrency <number>] <glob-pattern> [<glob-pattern> ...]
```
