我们在使用 man 手册的时候,可以使用man -f [keyword]去查询keyword的在线文档,但是这时候会报错:(图来源自网络)
这是因为我们还没有建立 man 手册的索引缓存;
我们可以使用 mandb 进行更新;之后就能使用 man -f 或者 man -k 命令进行查找手册;
[root@localhost tmp]# man -k aio aio (7) - POSIX asynchronous I/O overview aio.h (0p) - asynchronous input and output aio_cancel (3) - cancel an outstanding asynchronous I/O request aio_cancel (3p) - cancel an asynchronous I/O request aio_error (3) - get error status of asynchronous I/O operation aio_error (3p) - retrieve errors status for an asynchronous I/O operation aio_fsync (3) - asynchronous file synchronization aio_fsync (3p) - asynchronous file synchronization aio_init (3) - asynchronous I/O initialization aio_read (3) - asynchronous read aio_read (3p) - asynchronous read from a file aio_return (3) - get return status of asynchronous I/O operation aio_return (3p) - retrieve return status of an asynchronous I/O operation aio_suspend (3) - wait for asynchronous I/O operation or timeout aio_suspend (3p) - wait for an asynchronous I/O request aio_write (3) - asynchronous write aio_write (3p) - asynchronous write to a file
