SC2033 false positive

[zatnas]

Intention of shell code: I'm creating a function to automatically use sudo if the command before requires user elevation. It currently works but shellcheck does not want to play nice. This might probably be similar to #1200 .

For bugs

• Rule ID: SC2032 & SC2033
• My shellcheck version : 0.7.0 & online
• I tried on shellcheck.net and verified that this is still a problem on the latest commit

Here's a snippet or screenshot that shows the problem:

#!/bin/bash
pacman() {
	if ! command pacman "$@"; then
		echo "sudo: a password is required"
		sudo pacman "$@"
	fi
}

Here's what shellcheck currently says:

Line 3:
pacman() {
^-- SC2032: Use own script or sh -c '..' to run this from sudo.

Line 6:
sudo pacman "$@"
^-- SC2033: Shell functions can't be passed to external commands.

Here's what I wanted or expected to see:

No issues

You're right of course, but it's hard for ShellCheck to know that the function isn't trying to reinvoke itself with sudo.

As mentioned in the wiki, you can quote the name (sudo "pacman" "$@") to make ShellCheck realize this isn't referencing the function, or you can ignore it with a directive.
