什么条件可以解释此输出：
root@ip:/# find / -name "server.xml" -print
/etc/tomcat7/server.xml
root@ip:/# ls /var/lib/tomcat7/conf/server.xml
/var/lib/tomcat7/conf/server.xml
我以 root 身份运行它，并从根目录开始查找。我不明白为什么我用“ls”命令显示的文件没有出现在结果中。

答案1
/var/lib/tomcat7/conf如果是到 的符号链接，就会发生这种情况/etc/tomcat7。
默认情况下，find（无论如何 coreutils 版本）不会遵循符号链接。尝试使用-L标志：
find -L / -name "server.xml" -print
