You can address the above issues in one of three ways:
1. Manually correct the issue in the offending shell script;
2. Disable specific issues by adding the comment:

above the line that contains the issue, where NNNN is the error code;
3. Add '-e NNNN' to the SHELLCHECK_OPTS setting in your .yml action file.
