Question

I am running a script which is echoing the environment variables in .profile file and than I am running the script, but I am getting following error

I tried following:

node@node-virtual-machine:~$ cat env.sh 
#!/bin/bash

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

Instead of:

sh env.sh

You should run:

bash ./env.sh

Besides instead of:

source .profile

use:

source ~/.profile
