Bash support is available through the Bash extension.
When shellcheck is available bash-language-server will use it internally to provide diagnostics.
shellcheck:brew install shellcheck # macOS (HomeBrew)
apt-get install shellcheck # Ubuntu/Debian
pacman -S shellcheck # ArchLinux
dnf install shellcheck # Fedora
yum install shellcheck # CentOS/RHEL
zypper install shellcheck # openSUSE
choco install shellcheck # Windows (Chocolatey)
And verify it is available from your path:
which shellcheck
shellcheck --version
If you wish to customize the warnings/errors reported you just need to create a .shellcheckrc file. You can do this in the root of your project or in your home directory (~/.shellcheckrc). See: shellcheck documentation for more.
