mkdir creates a directory if it does not exist. We can use the mkdir -p option.
mkdir -p option
- Create intermediate directories as required.
- If this option is not specified, the full path prefix of each operand must already exist.
- On the other hand, with this option specified, no error will be reported if a directory given as an operand already exists.
- Intermediate directories are created with permission bits of rwxrwxrwx (0777) as modified by the current umask, plus write and search permission for the owner.
mkdir -p syntax
mkdir -p foo/bar/baz
will create directories foo, foo/bar, and foo/bar/baz if they don’t exist.
In the following example, we will use the mkdir command -p option to create a multi-level directory that does not exist.
➜ mkdir -p foo/bar/baz
We execute the “mkdir -p foo/bar/baz” command again. You will find that the command will not report any errors.
Next we use the mkdir -p option to create a directory named “baz2” under the directory “foo/bar“.
➜ mkdir -p foo/bar/baz2
ok. Created successfully.
So, when we do not confirm whether the directory exists, we can use the mkdir -p option to create it when the directory does not exist.
