1.cmatrix(还记得黑客帝国的字符流特效吗,就是他,hhh)
root@Mke:~# apt install cmatrix && cmatrix
2.统计常用的10个命令
history | awk '{CMD[$2]++;count++;}END { for (a in CMD)print CMD[a] " " CMD[a]/count*100 "% " a;}' | grep -v "./" | column -c3 -s " " -t | sort -nr | nl | head -n10
3.自动纠错(这里主要是目录)
[root@localhost chanzhieps]# shopt -s cdspell
假如cd /ect,(实际是想切换到etc)
