Add shebang to the top of your script: Add a shebang line to the top of your script:
```bash ```bash
#!/bin/bash #!/bin/bash
``` ```
Alternatively, if that is not possible / desirable, you can use the `--shell` switch: Or, for scripts that will not be executed (*e.g.*, `~/.bashrc`), use a directive:
```bash
# shellcheck shell=sh
```
If neither of those options are possible or desirable, you can invoke ShellCheck with the `--shell` switch:
```bash ```bash
shellcheck --shell=bash without-shebang.sh shellcheck --shell=bash without-shebang.sh
``` ```
