I just started reading Michael Hartl's book on Rails and I've run across a problem in the setup phase. Hartl keeps referring to making a file in my home directory, but I'm not quite sure how to do this. For example, when I try to setup the command line for sublime text the instructions tell me to do this: Assuming you've placed Sublime Text 2 in the Applications folder, and that you have a ~/bin directory in your path, you can run:
ln -s "/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl" ~/bin/subl
My problem is that I don't know how to put a ~/bin directory in my path. I know this is real basic but any help would be greatly appreciation.
create or edit ~/.profile
(works with both bash and zsh)
add the following
export PATH=$PATH:$HOME/bin
The line above is saying, overwrite the PATH
environment variable and set it to the previous path plus ~/bin
Now when you try to run a command, bash will look in all the colon separated paths in your PATH
environment variable for an executable.
To see your entire PATH
, type echo $PATH
in a terminal. Or better yet, type env
to see all environment variables.
$ mkdir ~/bin
$ sudo ln -s "/Applications/Sublime Text2.app/Contents/SharedSupport/bin/subl" /usr/bin/subl
export PATH=$PATH:~/bin
open current directory:
subl .
在你的~/.bashrc
文件中添加到结尾:
PATH="$HOME/bin:$PATH"
