# collections items remove

## Synopsis

```shell
omics publisher collections items remove
  --collection=COLLECTION_ID
  --datasource=DATASOURCE_ID
  --files=FILE|@FILE|STDIN
```

## Description

Remove files from a collection. Files can be specified as a comma-separated list, loaded from a file, or piped via stdin. After removing files, the collection will begin validation to update the collection's contents.

## Examples

Remove files using a comma-separated list.

```shell
omics publisher collections items remove \
  --collection my-collection \
  --datasource my-bucket \
  --files 'gs://bucket/file1.vcf,gs://bucket/file2.vcf'
```

Load files to remove from a text file.

```shell
omics publisher collections items remove \
  --collection my-collection \
  --datasource my-bucket \
  --files @files.txt
```

Pipe files from stdin.

```shell
cat files.txt | omics publisher collections items remove \
  --collection my-collection \
  --datasource my-bucket \
  --files -
```
