如何自动安装程序bash建议我安装?

我在考虑这个输出的用例:

The program 'tiger' is currently not installed. You can install it by typing: sudo apt-get install tiger 

如何让它提示我安装该软件包? 例如,它会输出:

 The program 'tiger' is currently not installed. You can install it by typing: sudo apt-get install tiger # Confirmation can go here [sudo] password for tim: The following NEW packages will be installed tiger tripwire 0 to upgrade, 11 to newly install, 0 to remove and 0 not to upgrade. Need to get 8,416 kB of archives. After this operation, 26.5 MB of additional disk space will be used. Do you want to continue? [Y/n] # and/or confirmation can go here 

我不想自己运行它。 我怎样才能让它自动完成, 并给我选择不安装?

如果将环境变量COMMAND_NOT_FOUND_INSTALL_PROMPT设置为1 ,就像

 export COMMAND_NOT_FOUND_INSTALL_PROMPT=1 

你会被问到是否要安装包:

 me@myhost:~$ tiger The program 'tiger' is currently not installed. You can install it by typing: sudo apt-get install tiger Do you want to install it? (N/y) 

如果你回答y它会运行

 sudo apt-get install tiger
