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.
ex:
to(){
touch $1
open $1
}
Now in any directory you are in you can type the command:
$ to example.sh
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 hello.sh
This command created and opened an empty file called hello.sh. Now inside of hello.sh we will include a basic hello world script. Add the following code to hello.sh:
#!/bin/bash
echo "Hello World!"
Now inside of your /bin directory type the following command into the terminal:
$ chmod +x hello.sh
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.sh
Hello World!
Now go make some custom scripts of your own!
edit: Make sure to restart your Terminal so that changes can take effect.
