find 命令
Linux中find常见用法示例
·find path -option [ -print ] [ -exec -ok command ] {} \;
find命令的参数；
pathname: find命令所查找的目录路径。例如用.来表示当前目录，用/来表示系统根目录。
-print： find命令将匹配的文件输出到标准输出。
-exec： find命令对匹配的文件执行该参数所给出的shell命令。相应命令的形式为’command’ { } \;，注意{ }和\；之间的空格。
-ok： 和-exec的作用相同，只不过以一种更为安全的模式来执行该参数所给出的shell命令，在执行每一个命令之前，都会给出提示，让用户来确定是否执行。 Continue reading find 命令

Fedora is not in the sudoers file

$su –
