Programming :: Bash Script - Source Not Found

I want to edit the environment with a bash script, a part of my script is showed in the post. Its not everything, but the rest is working fine. At the begin of my script I've the follow line Code: #!/bin/bash
set -e First I tried with this solution. Code: sudo chmod 777 /etc
sudo rm /etc/environment
echo 'PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/ruby/bin"' > */etc/environment
sudo chmod 755 /etc
source /etc/environment Error, source not found

The second solution was this:
Code: sudo chmod 777 /etc
sudo rm /etc/environment
echo 'PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/ruby/bin"' > */etc/environment
sudo chmod 755 /etc
. /etc/environment
This one didn't give an error, but if I try this:
Code: ruby -v got an error
so the environment didn't worked.

If I use both commands
Code: source /etc/environment
Code: . /etc/environment
In the terminal, without a bash script, it works, so if I do
Code: ruby -v
It works and showed the right version.
