mkdir：创建目录，常用参数-p。具体信息如下：
[[email protected] ~]# man mkdir Formatting page, please wait... MKDIR(1) User Commands MKDIR(1) NAME mkdir - make directories SYNOPSIS mkdir [OPTION]... DIRECTORY... DESCRIPTION Create the DIRECTORY(ies), if they do not already exist. Mandatory arguments to long options are mandatory for short options too. -m, --mode=MODE set file mode (as in chmod), not a=rwx - umask -p, --parents no error if existing, make parent directories as needed -v, --verbose print a message for each created directory -Z, --context=CTX set the SELinux security context of each created directory to CTX --help display this help and exit --version output version information and exit
参数解释：
1、-p：没有父目录时创建父目录，父目录存在不报错。
[[email protected] ~]# ls -lrt | grep "^d" drwxr-xr-x. 2 root root 4096 Mar 28 07:32 data drwxr-xr-x 2 root root 4096 Apr 4 18:43 hello drwxr-xr-x 2 root root 4096 Apr 4 18:44 world [[email protected] ~]# mkdir just/test/ mkdir: cannot create directory `just/test/‘: No such file or directory [[email protected] ~]# mkdir -p just/test/ [[email protected] ~]# ls -lrt | grep "^d" drwxr-xr-x. 2 root root 4096 Mar 28 07:32 data drwxr-xr-x 2 root root 4096 Apr 4 18:43 hello drwxr-xr-x 2 root root 4096 Apr 4 18:44 world drwxr-xr-x 3 root root 4096 Apr 4 18:52 just [[email protected] ~]# ls -lrt just/test/ total 0
2、-m：创建目录时设置文件模式。
[[email protected] ~]# mkdir hello [[email protected] ~]# ls -ld hello/ drwxr-xr-x 2 root root 4096 Apr 4 18:56 hello/ [[email protected] ~]# mkdir -m 644 world [[email protected] ~]# ls -ld world/ drw-r--r-- 2 root root 4096 Apr 4 18:57 world/
用户默认创建目录权限是755，可以通过-m指定创建目录权限。
3、-v：打印每个已创建目录信息。
[[email protected] ~]# mkdir -v hello mkdir: created directory `hello‘ [[email protected] ~]# ls -ld hello/ drwxr-xr-x 2 root root 4096 Apr 4 18:43 hello/ [[email protected] ~]# mkdir world [[email protected] ~]# ls -ld world/ drwxr-xr-x 2 root root 4096 Apr 4 18:44 world/
4、--help：打印帮助信息并退出。
