[OpenWrt-Devel] execute bit in board.d files

[mail at adrianschmutzler.de]

Hi,

I was just wondering why the execute bit for board.d subfiles is set.

In package/base-files/files/bin/board_detect:
[ -d "/etc/board.d/" -a ! -s "$CFG" ] && {
	for a in `ls /etc/board.d/*`; do
		[ -x $a ] || continue;
		$(. $a)
	done
}

So, to me it looks like the files are only sourced (preceding dot) and thus both the execute check as well as the execute bit are not required?

Despite, can someone explain me the purpose of the surrounding $() for $(. $a) ?

Best

Adrian
