示例

1、命令拼写不对

# puthon
No command 'puthon' found, did you mean:
 Command 'python' from package 'python-minimal' (main)
 Command 'python' from package 'python3' (main)
zsh: command not found: puthon

# fuck
python
Python 3.4.2

2、命令输错

# git brnch
git: 'brnch' is not a git command. See 'git --help'.

Did you mean this?
    branch

# fuck
git branch
* master

3、权限不够

# apt-get install vim
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

# fuck
sudo apt-get install vim
[sudo] password for nvbn:
Reading package lists... Done
