有时候我们有好多地址需要访问，不想全路径去切换，那我们就需要一些快捷命令跳到目标地址
可以用如下alias命令添加快捷地址
[sandwich@centos-elk ~]$ cd ~ [sandwich@centos-elk ~]$ echo 'alias elk="cd /home/sandwich/app/elk"'>>.bash_profile [sandwich@centos-elk ~]$ echo 'alias es="cd /home/sandwich/app/elk/elasticsearch-7.17.1"'>>.bash_profile [sandwich@centos-elk ~]$ echo 'alias logstash="cd /home/sandwich/app/elk/logstash-7.17.1"'>>.bash_profile [sandwich@centos-elk ~]$ echo 'alias kibana="cd /home/sandwich/app/elk/kibana-7.17.1-linux-x86_64"'>>.bash_profile [sandwich@centos-elk ~]$ echo 'alias logs="cd /log"'>>.bash_profile [sandwich@centos-elk ~]$ source .bash_profile [sandwich@centos-elk ~]$ pwd /home/sandwich [sandwich@centos-elk ~]$ elk [sandwich@centos-elk elk]$ pwd /home/sandwich/app/elk [sandwich@centos-elk elk]$ es [sandwich@centos-elk elasticsearch-7.17.1]$ pwd /home/sandwich/app/elk/elasticsearch-7.17.1
