Question

I’m setting up grails, and these are the commands the README indicates you should run for a unix machine. My problem is that the echo command doesn’t output anything like it should. I double checked and have the grails folder in the right directory.

> set GRAILS_HOME=~/grails

> export GRAILS_HOME

> echo ${GRAILS_HOME}

~/grails

Answer 1

you need to set the path variable:

export GRAILS_HOME=/path/to/grails
export PATH=$PATH:$GRAILS_HOME/bin

For OS X Lion you add these lines this is to your ~/.bash_profile file. This is the same as your /Users/macUsername/.bash_profile. After saving this edit, new terminal windows will have this effect in place. You can also run source ~/.bash_profile to make the change happen in your current terminal window.

On another *nix you would edit a slightly different file.

The .bash_profile file holds commands that run every time you start your terminal.
