Bash Version: 5.2
Patch Level: 26
Release Status: release

Description:

Using the following script with a function

#!/bin/bash
init() {
[ -n "$@" ] && echo $@
}
init $@

and calling the script as follows:

:~> LC_ALL=C . ./test.sh a b c d

gives the following error:

bash: [: too many arguments

Fix:

When assigning $@ to a parameter p and using that parameter as "$p" instead of 
"$@"
it works OK.
