Question about 41_snapshots-btrfs

[bkmo]

Just something that bothers me....
Why does this get printed in the terminal when 41_snapshots-btrfs is run from the terminal? What can I do to suppress the output of CAT in the terminal?

if [ ! -e "${prefix}/grub-btrfs.cfg" ]; then
echo ""
else
submenu 'Arch Linux snapshots' {
    configfile "${prefix}/grub-btrfs.cfg"
}
fi

Nevermind.....if I redirect it to > /dev/null I do not get the output from cat.

This needs to be done to create the snapshots menu with grub-mkconfig, though. The grub scripts work by writing things to stdout. grub-mkconfig collects the output of the scripts and incorporates it into grub.cfg.
