shellcheck

A Dagger module that lints shell scripts with ShellCheck.

Functions

Function	Description
check	Run shellcheck on every visible shell script (a @check).
scripts	The discovered scripts as Script objects, each individually checkable.
base	The container with shellcheck installed.

Usage

Install the module in your workspace:

dagger install github.com/dagger/shellcheck

Run the check:

dagger check                    # run every check in the workspace
dagger check shellcheck:check   # just the shellcheck check

Configuration

Skip scripts by glob pattern in dagger.toml:

[modules.shellcheck]
source = "github.com/dagger/shellcheck"
settings.exclude = ["vendor/**", "scripts/legacy.sh"]

Patterns are matched relative to your current working directory.

Working directory awareness

Script discovery finds **/*.sh at or below your current working directory, so running from a subdirectory checks only that subtree; script paths are reported relative to it.

Each script is checked in its own container, so results are cached per script — editing one script only re-checks that script.
