ubuntu 命令行错误命令提示：慢！！！

装了 ubuntu 10.4和升级后的版本都会有此问题，主要是

root@zanget:/#asdf

No command 'asdf' found, did you mean:

 Command 'asdfg' from package 'aoeui' (universe)

 Command 'sadf' from package 'sysstat' (main)

 Command 'sdf' form package 'sdf' (universe)

asdf : command not found

这常常使人非常沮丧，当敲错命令后，不得不按下CTRL'C来结束此次命令的运行。

让我们来看看此动作，ubuntu是如何做到的：

 

这项任务是由/etc/bash.bashrc里面的bash函数调用command_not_found_handle() 来实现的。

查看此包的详情：

root@zanget:~# dpkg --list | grep command-not-found
ii  command-not-found                    0.2.40ubuntu5                                     Suggest installation of packages in interact
ii  command-not-found-data               0.2.40ubuntu5                                     Set of data files for command-not-found.

移除：

 

dpkg -r command-not-found

dpkg -r command-not-found-data
