我们还需要手工安装一些别人已经编辑好的速记素材，比如官方的https://github.com/cheat/cheatsheets。这份素材已经位于安装目录，但默认没有启用。下面命令可以启用这份官方素材：

[root@localhost cjl]# sudo ln -s /usr/local/lib/python3.6/site-packages/usr/share/cheat /usr/share/cheat
[root@localhost cjl]# cheat ps
# To list every process on the system:
ps aux

# To list a process tree
ps axjf

# To list every process owned by foouser:
ps -aufoouser

# To list every process with a user-defined format:
ps -eo pid,user,command

# Exclude grep from your grepped output of ps.
# Add [] to the first letter. Ex: sshd -> [s]shd
ps aux | grep '[h]ttpd'
