目录相关指令
[root@Lettiy ~]# cd /usr/local[root@Lettiy local]# lsaegis bin etc games include lib lib64 libexec sbin share src[root@Lettiy ~]# mkdir mytest[root@Lettiy ~]# lsmytest[root@Lettiy mytest]# mkdir text.txt[root@Lettiy mytest]# lstext.txt文件处理指令（移动，删除，复制<cp 基本操作类似于mv>）
[root@Lettiy mytest]# mv text.txt newname.txt[root@Lettiy mytest]# lsnewname.txt[root@Lettiy mytest]# mv newname.txt newdir[root@Lettiy mytest]# lsnewdir[root@Lettiy mytest]# cd newdir[root@Lettiy newdir]# lsnewname.txt[root@Lettiy newdir]# lsnew1 new2 new3 new4 newname.txt[root@Lettiy newdir]# rm -f newname.txt[root@Lettiy newdir]# lsnew1 new2 new3 new4[root@Lettiy newdir]# rm -rf new4.txt[root@Lettiy newdir]# lsnew1 new2. new3[root@Lettiy newdir]# rm -rf -v new*removed directory: ‘new1'removed directory: ‘new2'removed directory: ‘new3'文件下载与解压

CentOS集成了yum，可配置源（repository）进行安装
[root@Lettiy newdir]# yum install postgresql[root@Lettiy newdir]# yum list[root@Lettiy newdir]# yum list|grep 'java'[root@Lettiy newdir]# rpm -ivh software.rpm文件更改/查看

保存：先ESC，然后输入：
wq:保存退出
q!:不保存退出
主要用于修改配置文件 ,例如：etc/proflie
端口和进程监控常用
[root@Lettiy newdir]# ps -ef|grep 'tomcat'root 19785 1 0 Aug12 ? 00:01:05 /usr/develop/java/jdk1.8.0_144/bin/java -Djava.util.logging.config.file=/usr/develop/tomcat/apache-tomcat-8.5.20/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djdk.tls.ephemeralDHKeySize=2048 -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -classpath /usr/develop/tomcat/apache-tomcat-8.5.20/bin/bootstrap.jar:/usr/develop/tomcat/apache-tomcat-8.5.20/bin/tomcat-juli.jar -Dcatalina.base=/usr/develop/tomcat/apache-tomcat-8.5.20 -Dcatalina.home=/usr/develop/tomcat/apache-tomcat-8.5.20 -Djava.io.tmpdir=/usr/develop/tomcat/apache-tomcat-8.5.20/temp org.apache.catalina.startup.Bootstrap startroot 22647 22470 0 23:58 pts/0 00:00:00 grep --color=auto tomcat本地文件上传
需利用lrzsz
yum install lrzsz然后使用rz sz即可上传下载。
