echo 'export JAVA_HOME=/home/node/jdk1.6.0_45' >> /home/node/.profile
echo 'export PATH=$PATH:$JAVA_HOME/bin' >> /home/node/.profile
cd /home/node/
source .profile
node@node-virtual-machine:~$ sh env.sh 
sudo: source: command not found

How to execute .profile within a script?

Answer 1

If .profile exists as /home/node/.profile, you have all that is necessary.

Answer 2

Instead of:

sh env.sh

You should run:

bash ./env.sh

Besides instead of:

source .profile

use:

source ~/.profile

Answer 3

Your script says /bin/bash at the top but you run it with sh which is probably dash on your system. You probably are already running Bash at the prompt, so you should say source env.sh instead of sh env.sh if you want the variables to be exposed to your terminal.
