linux基础入门--目录创建及Linux应用程序的组成部分

Linux目录创建及切换显示

cd pwd lsmkdir-p 层级创建目录，(在当没有父目录清空下，需要创建父目录和子目录的情况下执行)-v 显示创建过程-m MODE 创建时，同时赋予权限 rmdir 删除空目录-p 删除层级一级目录(例如:/a/b/c/d/)，但是无法删除(/a/b/c,e,d/f）-v 显示 tree 显示目录层级结构-d 只显示目录-L level 指定显示的层级结构-P pattern 只显示由指定patter 如何创建/tmp/x/y1 /tmp/x/y2 /tmp/x/y1/a
/tmp/x/y1/b分析首先得创建/tmp/x/y1,y2然后分别创建/tmp/x/y1/a 和/tmp/x/y2/b【实例1】[root@Cody ~]# mkdir
-pv /tmp/x/{y1/a,y2/b}mkdir: created
directory `/tmp/x'mkdir: created
directory `/tmp/x/y1'mkdir: created
directory `/tmp/x/y1/a'mkdir: created
directory `/tmp/x/y2'mkdir: created
directory `/tmp/x/y2/b'[root@Cody ~]# ls
/tmp/xy1 y2[root@Cody ~]# ls
/tmp/x/y1a[root@Cody ~]# ls
/tmp/x/y2b【实例2】联合查看bash特性的命令行展开1.如何创建/tmp/x/y1
/tmp/x/y2 /tmp/x/y1/a /tmp/x/y1/b /tmp/x/y2/a /tmp/x/y2/bmdkir -pv /tmp/x/{y1,y2}/{a,b}[root@Cody
~]# mkdir -pv /tmp/x/{y1/{a,b},y2/{a,b}}mkdir:
created directory `/tmp/x'mkdir:
created directory `/tmp/x/y1'mkdir:
created directory `/tmp/x/y1/a'mkdir:
created directory `/tmp/x/y1/b'mkdir:
created directory `/tmp/x/y2'mkdir:
created directory `/tmp/x/y2/a'mkdir:
created directory `/tmp/x/y2/b' 2.如何创建x_m ,y_m ,x_n y_n mkdir {x,y}_{m,n} 3.如何创建/tmp/bin，/tmp/sbin ,/tmp/usr ,/tmp/usr/bin ,/tmp/usr/sbin mkdir -pv /tmp/{bin,sbin,usr/{bin,sbin}}

1、二进制程序/bin , /sbin /usr/bin
/usr/sbin /usr/local/bin /usr/local/sbin 2、库文件/lib /lib64 /usr/lib /usr/lib64 /usr/local/lib /usr/local/lib64 3、配置文件/etc /etcDIRECTORY
/usr/localetc 4、帮助文件/usr/share/man
/usr/share/doc
/usr/localshare/man /usr/local/share/doc
