# go-hashfiles # go-hashfiles
This action is to compute the SHA256 checksum of specified files.
**NOTE:** This action is written in Go. Please make sure the `runs-on` runner supports running Go actions.
## Usage
``` yml
- uses: actions/go-hashfiles@v0.0.1
with:
# The working dir for the action.
# Default: ${{ github.workspace }}
workdir: ''
# The patterns used to match files.
# Multiple patterns should be seperated with `\n`
patterns: ''
```
## Output
|Output Item|Description|
|---|---|
|hash|The computed checksum|
|matched-files|The files matched by the patterns|
## Example
``` yml
- uses: actions/go-hashfiles@v0.0.1
id: get-hash
with:
patterns: |-
go.sum
./admin/*
**/package-lock.json
- name: Echo hash
run: echo ${{ steps.get-hash.outputs.hash }}
