cheat命令 == Linux命令小抄大全

[[email protected] ~]# cheat -d        
/root/.cheat
/usr/lib/python2.6/site-packages/cheat/cheatsheets #cheat默认的常用命令保存路径

修改

[[email protected] ~]# mkdir /opt/cheats
[[email protected] ~]# vim ~/.bashrc                    #设置参数（见参数）
[[email protected] ~]# source ~/.bashrc                 #使设置生效
[[email protected] ~]# cheat -d
/opt/cheat                                                    #默认cheat保存路径已经改变
/usr/lib/python2.6/site-packages/cheat/cheatsheets

其中：在~/.bashrc末尾添加的具体参数如下：

export DEFAULT_CHEAT_DIR=‘/opt/cheat‘    #设置cheat默认保存路径
export EDITOR=/usr/bin/vim         #设置默认编辑器（可根据自己喜好添加，如nano等）
export CHEATCOLORS=true            #语法高亮
