但似乎只能搜到某些文件。。
可是很多文件找不到。。比如我们home目录下完全搜不到。。
为什么啊

$man locate

BUGS
The locate program may fail to list some files that are present, or may
list files that have been removed from the system. This is because locate
only reports files that are present in the database, which is typically only
regenerated once a week by the /System/Library/LaunchDaemons/com.apple.
locate.plist job. Use find(1) to locate files that are of a more transitory
nature.
The locate database is typically built by user ``nobody'' and the
locate.updatedb(8) utility skips directories which are not readable for user
``nobody'', group ``nobody'', or world. For example, if your HOME
directory is not world-readable, none of your files are in the database.
The locate database is not byte order independent. It is not possible
to share the databases between machines with different byte order. The
current locate implementation understands databases in host byte order or
network byte order if both architectures use the same integer size. So on a
FreeBSD/i386 machine (little endian), you can read a locate database which
was built on SunOS/sparc machine (big endian, net).
The locate utility does not recognize multibyte characters. | j*****I
