I downloaded the latest version of Scala and saved it to /opt folder. Then I tried to add /opt/scala-2.11.2/bin to the PATH in order to have easier access to commands like scala and scalac. After executing the command :
export PATH=$PATH:/opt/scala-2.11.2/bin/
and then :
echo $PATH
I see the path in there. At that time I can also use the commands scala and scalac.
Then if I close the terminal and restart , the path /opt/scala-2.11.2/bin/ is not in echo $PATH anymore. And thus I can not execute the commands . What is my problem ?
set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH:$/opt/scala-2.11.2/bin" fi

, because$HOME/bin
does not exists, put it in the last line of the .profile file – tttony Aug 07 '14 at 16:33
