In #212 we have a case of broken NX caused by an undefined s_readelf variable. This thing is actually caught by shellcheck if you run it on the concatenated script without flags, having the inline annotations take care of everything:
$ ./shellcheck ./checksec
In ./cso.sh line 726:
if [[ $(${s_readelf} -l "${1}" 2> /dev/null | grep -A 1 'GNU_STACK' | sed 'N;s/\n//g' | grep -Eo "0x[0-9a-f]{16}" | grep -v 0x0000000000000000 | wc -l) -gt 0 ]]; then
