Ubuntu22.04桌面版的 mkdir 命令笔记

mkdir 用于创建文件夹

mkdir -p 自动创建父文件夹,父文件夹存不存在都没关系, 等效 mkdir --parents

mkdir --help

用法：mkdir [选项]... 目录... 若指定<目录>不存在则创建目录。

必选参数对长短选项同时适用。 -m, --mode=模式 设置权限模式（类似chmod），而不是 a=rwx 减 umask -p, --parents 需要时创建目标目录的上层目录，但即使这些目录已存在 也不当作错误处理 -v, --verbose 每次创建新目录都显示信息 -Z 设置每个创建的目录的 SELinux 安全上下文为默认类型 --context[=CTX] 类似 -Z，或如果指定了 CTX，则将 SELinux 或 SMACK 安全 上下文设置为 CTX 对应的值 --help 显示此帮助信息并退出 --version 显示版本信息并退出

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     set SELinux security context of each created directory to the default type

       --context[=CTX]
              like -Z, or if CTX is specified then set the SELinux or SMACK security context to CTX

       --help display this help and exit

       --version
              output version information and exit

12.3 ‘mkdir’: Make directories
==============================

‘mkdir’ creates directories with the specified names.  Synopsis:

     mkdir [OPTION]... NAME...

   ‘mkdir’ creates each directory NAME in the order given.  It reports
an error if NAME already exists, unless the ‘-p’ option is given and
NAME is a directory.

   The program accepts the following options.  Also see *note Common
options::.

‘-m MODE’
‘--mode=MODE’
     Set the file permission bits of created directories to MODE, which
     uses the same syntax as in ‘chmod’ and uses ‘a=rwx’ (read, write
     and execute allowed for everyone) for the point of the departure.
     *Note File permissions::.

     Normally the directory has the desired file mode bits at the moment
     it is created.  As a GNU extension, MODE may also mention special
     mode bits, but in this case there may be a temporary window during
     which the directory exists but its special mode bits are incorrect.
     *Note Directory Setuid and Setgid::, for how the set-user-ID and
     set-group-ID bits of directories are inherited unless overridden in
     this way.

‘-p’
‘--parents’
     Make any missing parent directories for each argument, setting
     their file permission bits to the umask modified by ‘u+wx’.  Ignore
     existing parent directories, and do not change their file
     permission bits.

     To set the file permission bits of any newly-created parent
     directories to a value that includes ‘u+wx’, you can set the umask
     before invoking ‘mkdir’.  For example, if the shell command ‘(umask
     u=rwx,go=rx; mkdir -p P/Q)’ creates the parent ‘P’ it sets the
     parent’s permission bits to ‘u=rwx,go=rx’.  To set a parent’s
     special mode bits as well, you can invoke ‘chmod’ after ‘mkdir’.
     *Note Directory Setuid and Setgid::, for how the set-user-ID and
     set-group-ID bits of newly-created parent directories are
     inherited.

‘-v’
‘--verbose’
     Print a message for each created directory.  This is most useful
     with ‘--parents’.

‘-Z’
‘--context[=CONTEXT]’
     Without a specified CONTEXT, adjust the SELinux security context
     according to the system default type for destination files,
     similarly to the ‘restorecon’ command.  The long form of this
     option with a specific context specified, will set the context for
     newly created files only.  With a specified context, if both
     SELinux and SMACK are disabled, a warning is issued.

   An exit status of zero indicates success, and a nonzero value
indicates failure.
