So, it is better to run something like: find / -type f -perm /111 | while read f; do readelf -Ws $f 2>/dev/null | fgrep -q sysctl(a)GLIBC && echo $f; done Jakub - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

What were you using for search criteria? A challenge is to weed out code that runs on BSDs where people do use sysctl.
