考虑到子目录的变体(未经测试):

A variation that takes into account subdirectories (untested):

find /var/www -type f -exec sed -i 's/privelages/privileges/g' {} ;

这将find /var/www 下的所有文件(不是目录，由-type f 指定)，并执行sed 命令在它找到的每个文件上用特权"替换特权".

This will find all files (not directories, specified by -type f) under /var/www, and perform a sed command to replace "privelages" with "privileges" on each file it finds.
