For example, if you’re constantly forgetting about the hidden dot files on your machine, you can redefine the way the shell handles the ls command: $ alias ls="ls -a" Yet another use for aliases is to redefine a command to add some default options. This is required when a command consists of more than one word. Notice the use of quotes around the command. For example, if you are often changing directories to somewhere deep in the hierarchy, you can set up an alias that will allow you to go there quickly: $ alias fdocs="cd ~/Documents/Corporate/Master/Forecasts" For example, if you are always typing sl instead of ls, you could define the following alias so that you don’t get scolded by the shell again: $ alias sl=lsĪnother use for aliases is to create a simple command for a longer one. One common use of aliases is to accommodate fat-fingering of commands. Where name is the name of the command alias you are defining, and command is the command that’s actually executed by the shell when you invoke the alias. To define an alias for a command, use the following syntax: alias name=command It’s a shortcut to a file instead of a shortcut for a command. Finder aliases are closer to the Unix concept of a symbolic link. It’s important to note that these are not the same aliases as those defined in the Finder. Aliases are commonly used to create a shorter command name for long command strings so that they’re a bit more manageable or to rename commonly used commands. In addition to searching the PATH for commands, the bash shell lets you define a set of aliases bash_profile file: $ source ~/.bash_profile If you don’t want to close your shell and start a new one, you can use the source command to load the contents of the. bash_profile is only read when the shell is created, any changes you make to it won’t take effect until you start the next shell. This causes the PATH environment variable to be set to the given string each time you open a new Terminal window. bash_profile file in your Home directory and add the following line: PATH=$PATH:~/bin:/Developer/Tools For example, if you wanted to permanently modify the PATH that the shell uses to resolve commands, you could create a. bash_profile, which is used to customize the shell. You could use this to clean up files before you log out.īy default, these files don’t exist as part of a user’s Home directory until you create them.

If bash doesn’t find this file, it looks for. This allows you to customize the shell to your liking.

Boom.Contains environment variables and commands that are read and executed every time you create a new Terminal window and a shell is created for it, or when you SSH into your machine and are presented with a prompt. If you have Homebrew already, it should be immediately evident. Or, if you are the reckless or impatient sort, you can do what I did and press on by entering brew doctor into the terminal. I have only been diving into the dev game since the start of the year (and until today was only familiar setting things up on PC/Linux), so rather than potentially leading you astray, I suggest you check out for guidance on all things Homebrew. As was the case for me, there's a chance you may already have a version of Homebrew installed.

It appears that version and the version instructed above are just two different roads leading to the same destination. meaning I had installed Homebrew according to the instructions on their actual site. Prior to pasting the above into the terminal, I had used: Encountered that very same issue! For me, it was quickly resolved, though:
