I want to set path permanently in centos. I am able to set path, But when i logout and login the path is going.

Please tell me how to set path permanently


Depending on the shell you are running (probably bash) you set the path in your .bash_profile file. The file is in your home directory and you can add to the entries there:

# User specific environment and startup programs


export PATH

Or just:

export PATH=$HOME/bin:/usr/local/bin:${PATH}

This gives precidence to executable files in your personal bin directory, then to those in /usr/local/bin, and finally to the default PATH environment. Note the {} around PATH. That allows a recursive path definition like this, especially if the existing PATH environment is complexly defined. It is safer than not useing the curly braces.
