ShellCheck

GitHub action for ShellCheck.

Example

on:
  push:
    branch:
      - master

name: 'Trigger: Push action'

jobs:
  shellcheck:
    name: Shellcheck
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Run ShellCheck
      uses: ludeeus/action-shellcheck@master

Globally disable checks

To disable specific checks add it to a SHELLCHECK_OPTS env key in the job definition.

example:

    ...
    - name: Run ShellCheck
      uses: ludeeus/action-shellcheck@master
      env:
        SHELLCHECK_OPTS: -e SC2059 -e SC2034 -e SC1090

Ignore paths

You can use the ignore input to disable specific directories.

sample structure:
sample/directory/with/files/toignore/test.sh
sample/directory/with/files/test.sh

example:

    ...
    - name: Run ShellCheck
      uses: ludeeus/action-shellcheck@master
      with:
        ignore: toignore

This will skip sample/directory/with/files/toignore/test.sh

Minimum severity of errors to consider (error, warning, info, style)

You can use the severity input to not fail until specified severity is met, for example fail only if there are errors in scripts but ignore styling, info and warnings.

example:

    ...
    - name: Run ShellCheck
      uses: ludeeus/action-shellcheck@master
      with:
        severity: error

Run shellcheck with all paths in a single invocation

If you run into SC1090/SC1091 errors you may need to tell shellcheck to check all files at once:

    ...
    - name: Run ShellCheck
      uses: ludeeus/action-shellcheck@master
      with:
        check_together: 'yes'

This can turn into a problem if you have enough script files to overwhelm the maximum argv length on your system.

Run shellcheck only in a single directory

If you have multiple directories with scripts, but only want to scan one of them, you can use the following configuration:

   ...
   - name: Run ShellCheck
     uses: ludeeus/action-shellcheck@master
     with:
       scandir: './scripts'
