我使用过的Linux命令之apropos - 根据关键字搜索命令

2011-11-08 19:26 387 查看

用途说明

因为Linux的Shell中使用的是命令行方式，有时候会忘记执行特定任务的命令，就可以使用apropos找出来。等同于man -k，在使用的时候还是觉得用man -k来的好，毕竟apropos这个命令有些难记。

此命令需要指定一个keyword作为参数，查找与该keyword有关的命令。手册页中的解释是：在whatis数据库中搜索字符串。search the whatis database for strings。

常用参数

无。

命令格式为：apropos keyword

等同于：man -k keyword

使用示例

示例一

[root@web ~]# apropos who

at.allow [at] (5) - determine who can submit jobs via at or batch

at.deny [at] (5) - determine who can submit jobs via at or batch

jwhois (1) - client for the whois service

jwhois (rpm) - Internet whois/nicname client.

w (1) - Show who is logged on and what they are doing

who (1) - show who is logged on

who (1p) - display who is on the system

whoami (1) - print effective userid

[root@web ~]# man -k who

at.allow [at] (5) - determine who can submit jobs via at or batch

at.deny [at] (5) - determine who can submit jobs via at or batch

jwhois (1) - client for the whois service

jwhois (rpm) - Internet whois/nicname client.

w (1) - Show who is logged on and what they are doing

who (1) - show who is logged on

who (1p) - display who is on the system

whoami (1) - print effective userid

从以上输出来看，apropos和man -k的输出是相同的。

示例二

[root@web ~]# apropos apropos

apropos (1) - search the whatis database for strings

man (rpm) - A set of documentation tools: man, apropos and whatis.

[root@web ~]# man -k apropos

apropos (1) - search the whatis database for strings

man (rpm) - A set of documentation tools: man, apropos and whatis.
