How To Practise Complex Directory Tree Using Mkdir -P Ascendence Inwards Unix

One of the most mutual chore inwards whatever Linux is creating directories, too most of us pass a lot of fourth dimension creating complex directory construction inwards UNIX.  I am certain you lot know close mkdir command, nosotros receive got been using this ascendancy inwards almost every operating arrangement e..g DOS, Windows, Linux, OS/2, Solaris or many other *NIX operating system. It is i of the basic ascendancy but every bit of import every bit find, grep or chmod.  mkdir stands for "make directory" too this ascendancy is literally used to create directories. Suppose, you lot ask to create a directory tree similar /opt/software/java/app/config, how are you lot going to create these directories? One past times i right? Well, aye you lot tin role mkdir too ascendancy to create these directories i past times i every bit shown inwards below instance :

$ cd /opt $ mkdir software  $ cd software $ mkdir coffee  $ cd coffee $ mkdir app  $ cd app $ pwd /opt/software/java/app/config

This would accept almost 8 commands to create to a higher identify directory structure, unfortunately you lot exactly tin non type mkdir /opt/software/java/app/config,  because  parent directories does non exists.

It volition only fail, past times the agency in that place is a trace a fast i on here, you lot tin role mkdir -p command choice to create intermediate directories along the agency e.g. if /opt exists but /opt/software doesn't you lot tin even thence use mkdir -p /opt/software/java/app/config to create exact same directory construction every bit shown below

[#  ]$ mkdir -p software/java/app/config [#  ]$ [#  ]$ pwd /home/john [#  ]$ cd software/java/app/config/ [#  /software/java/app/config]$
 

mkdir ascendancy Example inwards UNIX

Interestingly, mkdir is i of the simplest ascendancy inwards UNIX, I approximate solely i which is roughly mo unproblematic is pwd. mkdir stands for "make directory" too exactly has ii top dog ascendancy line of piece of job option, other than -v which stands for verbose too prints a message for each created directory.

• -m  stands for mode, too used  to educate the access agency for the novel directory.
• -p   used to create raise directories if non exist

For example, next ascendancy volition set initial permission of novel directory to 777, thence that everyone tin access it.

mkdir -m 777  /test

On the other hand, our -p choice volition create test/coding/java directory inwards i shot.

mkdir -p  /test/coding/java

You tin create fifty-fifty really complex directory construction similar UNIX file arrangement (as shown inwards next diagram) using mkdir -p command.

mkdir command: "Permission denied" fault inwards UNIX

By the way, old if you lot essay to create a directory similar this(mostly inwards directory you lot don't own) :

$ mkdir dropbox

you lot may run across next error

mkdir: cannot create directory 'dropbox': Permission denied

As fault message is suggesting, you lot don't receive got permission to create this directory inwards your electrical current working directory. You tin role the ls (list) ascendancy to figure out what permission you lot receive got inwards your electrical current working directory.

I am certain this unproblematic mkdir command choice volition salve your immense fourth dimension too attempt piece working inwards UNIX. It's groovy tool to create or replicate complex directory construction or tweak them. Ever since I receive got learned this trick, I don't shout out back creating directories i past times i inwards UNIX. So remember, mkdir -p command allow you to create intermediate directory along the way.
