Use a [[Directive]] to point shellcheck to a fixed location it can read instead.
ShellCheck v0.7.2+ will strip a single expansion followed by a slash, e.g. `${var}/util.sh` or `$(dirname "${BASH_SOURCE[0]}")/util.sh`, and treat them as `./util.sh`. This allowing the use of `source-path` directives or `-P` flags to specify the a location.
### Exceptions:
If you don't care that ShellCheck is unable to account for the file, specify `# shellcheck source=/dev/null`.
#### shellcheck -P *SOURCEPATH*, --source-path=*SOURCEPATH*
`shellcheck -P dir1:dir2/libs`
Specify paths to search for sourced files, separated by `:` on Unix and `;` on Windows. Absolute paths will also be rooted in these.
The special path ***`SCRIPTDIR`*** can be used to specify searching the currently checked script's directory, as in **`-P SCRIPTDIR`** or **`-P SCRIPTDIR/../libs`**. Subsequent `-P` flags accumulate and take precedence.
If you don't care that ShellCheck is unable to account for the file, specify `# shellcheck source=/dev/null`.
