Create Custom Terminal Commands

I spent some time today building custom terminal commands and I thought I would write about two simple ways to create your own custom commands. Custom bash scripts are a great way to automate redundant tasks. The examples below will give you a simple starting point for developing your own custom bash scripts.

 1 - Create a custom command inside of your bash profile.

Open your terminal and type:

$ open ~/.bash_profile

This command will open up your bash profile. Inside of your bash profile you can write custom terminal commands using the syntax below.

  touch $1  
  open $1

Now in any directory you are in you can type the command:

$ to

This will create (touch) a new file and immediately open it.

 2 - Add a custom shell script to your PATH

Open your bash profile. (See above.) If the following line isn’t present inside of your bash profile then add it somewhere in your bash profile.

export PATH=$PATH":$HOME/bin"

That line adds the bin folder to your PATH variable. Now navigate to your /bin folder and create a new file. We’ll use our new command that we created above:

$ to

This command created and opened an empty file called Now inside of we will include a basic hello world script. Add the following code to

echo "Hello World!"

Now inside of your /bin directory type the following command into the terminal:

$ chmod +x   

That command made it so that our shell script can be called and executed. (It changes the access permissions.)
Now from any directory you will get the following result:

Hello World!

Now go make some custom scripts of your own!

edit: Make sure to restart your Terminal so that changes can take effect.
