Making path change in .bash_profile and then how to refresh or reload

whenever you log into your linux and open a terminal, do this.

$pwd

This will show you your home directory. Typically, if you are root it is

/root

If you are having a user account in your name, it should be

/home/myName

Now, try this at the prompt,

$ls -all

And look for .bash_profile This file is the one who knows what paths are set in your account

You can add more paths to it and then save it. Once .bash_profile is saved, in order to make changes effective, you will need to do

$. .bash_profile
[Note the two dots before bash_profile]

OR


$source .bash_profile


And then do,

$echo $PATH

you will be able to see new paths shown.
