一、相对和绝对路径
相对路径
相对当前目录位置的路径
[[email protected]_46_188_centos /]# cd /usr/ [[email protected]_46_188_centos usr]# ls bin etc games include lib lib64 libexec local sbin share src tmp [[email protected]_46_188_centos usr]# [[email protected]_46_188_centos php]# ls bin etc include lib php
绝对路径
从根开始的路径
[[email protected]_46_188_centos fxq]# [[email protected]_46_188_centos network-scripts]# ls ifcfg-eth0 ifdown-TeamPort ifdown-ippp ifdown-ppp ifup ifup-bnep ifup-ipv6 ifup-post ifup-tunnel network-functions-ipv6 ifcfg-lo ifdown-bnep ifdown-ipv6 ifdown-routes ifup-Team ifup-eth ifup-isdn ifup-ppp ifup-wireless ifdown ifdown-eth ifdown-isdn ifdown-sit ifup-TeamPort ifup-ib ifup-plip ifup-routes init.ipv6-globalifdown-Team ifdown-ib ifdown-post ifdown-tunnel ifup-aliases ifup-ippp ifup-plusb ifup-sit network-functions [[email protected]_46_188_centos network-scripts]#
二、 cd命令
cd 进入目录
cd - 进入上一次所在的目录
[[email protected]_46_188_centos usr]# cd local/php/ [[email protected]_46_188_centos php]# ls bin etc include lib php [[email protected]_46_188_centos php]# /usr [[email protected]_46_188_centos usr]# pwd /usr [[email protected]_46_188_centos usr]# cd - /usr/local/php
cd ~ 进入用户家目录
[[email protected]_46_188_centos ~]# [[email protected]_46_188_centos ~]# pwd /root [[email protected]_46_188_centos ~]# [[email protected]_46_188_centos ~]# pwd /root [[email protected]_46_188_centos ~]#
cd .. 进入到上一级目录
[[email protected]_46_188_centos ~]# pwd /root [[email protected]_46_188_centos ~]# [[email protected]_46_188_centos /]# pwd/ [[email protected]_46_188_centos /]#
三、创建和删除目录mkdir/rmdir
mkdir 创建目录
mkdir -p /tmp/fxq/1/2 一次创建一系列目录
[[email protected]_46_188_centos /]# [[email protected]_46_188_centos /]# cd /tmp/fxq [[email protected]_46_188_centos fxq]# ls 1 [[email protected]_46_188_centos fxq]# cd 1/ [[email protected]_46_188_centos 1]# ls 2 [[email protected]_46_188_centos 1]# tree /tmp/fxq/tmp/fxq `-- 1 `-- 2 2 directories, 0 files
rmdir 删除空目录
rmdir -p /tmp/fxq/1/2 级联删除目录
四、 rm命令
rm 删除文件
[[email protected]_46_188_centos 1]# ls 1.txt 2 test1 [[email protected]_46_188_centos 1]# rm: remove regular empty file ‘1.txt‘? [[email protected]_46_188_centos 1]# ls 2 test1 [[email protected]_46_188_centos 1]#
rm -r 删除目录
[[email protected]_46_188_centos 1]# ls 2 test1 [[email protected]_46_188_centos 1]# rm: remove directory ‘/tmp/fxq/1/2/‘? [[email protected]_46_188_centos 1]# ls test1 [[email protected]_46_188_centos 1]#
rm -rf 强制删除文件或目录
[[email protected]_46_188_centos fxq]# tree. |-- 1| |-- 1.txt | `-- test1`-- 2 3 directories, 1 file [[email protected]_46_188_centos fxq]# removed directory: ‘/tmp/fxq/1/test1‘ removed ‘/tmp/fxq/1/1.txt‘ removed directory: ‘/tmp/fxq/1/‘ [[email protected]_46_188_centos fxq]#
-f 加上-f选项删除不存在的文件或目录时不提示信息。
[[email protected]_46_188_centos ~]# cd /tmp/fxq [[email protected]_46_188_centos fxq]# rm -rfv /tmp/fxq/1 [[email protected]_46_188_centos fxq]#
