Platform

Linux

Version

5.6.0

What steps will reproduce the bug?

• os: nixos (25.11.20250731.8679b16 (Xantusia))
• neovim lsp config: https://github.com/neovim/nvim-lspconfig/blob/5a49a97f9d3de5c39a2b18d583035285b3640cb0/lsp/bashls.lua#L12-L29

How often does it reproduce? Is there a required condition?

All the time

What is the expected behavior?

Complete for native executables.

What do you see instead?

No completion for native commands
Only shell builtins would appear in completion

Additional information

I didn't know bashls can complete commands until I saw #294.
Not sure whether related but, nixos neither use pkg-config or install bash-completion under /usr/shared, so this might not work:

bash-language-server/server/src/get-options.sh

Lines 4 to 19 in d531143

	COMPLETIONSDIR="$(pkg-config --variable=completionsdir bash-completion)"
	if (( $? == 0 ))
	then
	COMPLETIONSRC="$(dirname "$COMPLETIONSDIR")/bash_completion"
	else
	# Fallback if pkg-config fails
	if [ "$(uname -s)" = "Darwin" ]
	then
	# Running macOS
	COMPLETIONSRC="$(brew --prefix)/etc/bash_completion"
	else
	# Suppose running Linux
	COMPLETIONSRC="${PREFIX:-/usr}/share/bash-completion/bash_completion"
	fi
	fi

And I guess it's because bashls does not search on /home/<user>/.nix-profile/bin(shouldn't it search on $PATH?)
Some executables under /bin are presented in completion.
