Describe the bug /usr/share/lynis/include/tests_kernel line 695 is generating the error

line 695
                        FOUND_VMLINUZ=$(${LSBINARY} -v ${ROOTDIR}boot/vm[l0-9]* 2> /dev/null | ${GREPBINARY} -v '\-rescue\-' | ${TAILBINARY} -1)

grep: warning: stray \ before -

for the same reason

root@electron# mybug=$(ls -v /boot/vm[l0-9]* | grep -v '\-rescue\-' | tail -1)
grep: warning: stray \ before -
root@electron# echo $mybug
/boot/vmlinuz-6.9.10-200.fc40.x86_64

Version

• Distribution
• fedora 40
• Lynis version 3.1.1

Expected behavior it works but perhaps something is wrong with this command

[garberw]

root@electron# FOUND_VMLINUZ=$(ls -v /boot/vm[l0-9]* 2> /dev/null | grep -v '\-rescue-' | tail -1)
root@electron# echo $FOUND_VMLINUZ 
/boot/vmlinuz-6.9.11-200.fc40.x86_64

the solution is that you need grep -v '\-rescue-' and not grep -v '\-rescue\-' the second one has a backslash on the second '-' which is wrong.
