重建 locate.database 文件 Dec 04, 2015
[在线编辑]locate
locate 是快速定位文件的好工具，爱不释手（zhuang B），不过需要定时更新数据库。由于手贱将/var/db/locate.database文件删除了，导致如下的错误：
$ locate -0Scims
locate: mmap(2) not implemented
WARNING: The locate database (/var/db/locate.database) does not exist.
To create the database, run the following command:
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist
Please be aware that the database can take some time to generate; once
the database has been created, this message will no longer appear.
当然，如果你按说明执行 launchctl 命令行，/var/db/locate.database 文件是不会被重建的(我这里是这样)。那该怎么操作呢？其实，执行更新命令 /usr/libexec/locate.updatedb 即可。具体操作，如下：(命令执行有点慢，可以去喝杯 coffee)
$ sudo /usr/libexec/locate.updatedb
Ok，locate 又荣归了。
