Adding command-line in cmd

Question

Is there any way to create a command on Command Prompt like I want to create a command named createdirectory(I know there is an existing command for that but take this as an example) . when i execute the command "createdirectory" it will run a python file. I want it in such a way that i can run this command from anywhere any disk volume or any folder.

If you know anything then please post your answer.

Thanks!

Shell commands are basically either aliases or programs stored on disk. You can write your programs put them in some directory and add that directory path to the shell's PATH variable.

Let's say you have a program called create.py which creates the directories. You can follow these two ways to make them available as command on a shell

Assume create.py is present in /home/bob/scripts directory

Create a wrapper script

1. Create a file called createDirectory with below content in /home/bob/scripts

   python /home/bob/scripts/create.py $*

2. Add /home/bob/scripts to the PATH

    export PATH="$PATH:/home/bob/scripts"

Using aliases

1. Run the alias command

   alias createDirectory="python /home/bob/scripts/create.py"

Usage

createDirectory <whatever> <arguments> <your> <program> <expects>

NOTE : You can add this alias command and export command to ~/.bashrc file so that it is run when you start a shell
