To find all symlinks to /etc/resolv.conf, use the find command as follows:
# find /path/to/dir -lname /path/to/file
# find / -lname /etc/resolv.conf/path/to/file is a symbolic link whose contents match shell pattern pattern. The metacharacters do not treat / or . specially. The -ilname FILE options is like -lname, but the match is case insensitive:
# find / -ilname resolv.conf
