# GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash nomodeset”
#
# The quotes are Unicode quotes, not valid in the shell and probably
# caused by copying a line out of a web page. This is parsed as an
# instruction to run the 'splash' command with argument 'nomodeset”'
# and with the GRUB_CMDLINE_LINUX_DEFAULT environment variable set
# to '”quiet'. 'sh -n' allows this because this is a valid parse
# and it's possible that the command 'splash' might exist, but what
# we need to know is whether sourcing the file will fail.
#
# Unfortunately this test may involve executing code. However, this
# file is already sourced as root when running update-grub, so it
# seems unlikely that this could do any further harm.
