Users with Existing bsh, bash, korn or zsh Accounts

The following instructions tell you how to set up HEPiX for an already existing account using bsh, bash, korn or zsh. Users with new accounts should instead follow the instructions in Logging In. Users with already existing accounts using csh and tcsh should instead follow the instructions in for Users with Existing csh and tcsh Accounts. Do not log out after you make these changes. Keep the existing session up and start a new session to check that your log in still works properly. If the new log in has problems, you will want your original session to make any corrections.

Copy your $HOME/.profile and any other files our configuration may use just in case you need to go back to them:

    > cd $HOME
    > cp .profile original.profile
    
Create the directory .hepix and insert the file that identifies babar as the preferred group. This will cause the BABAR-specific environment to be established.
    > mkdir $HOME/.hepix
    > cp /afs/slac/g/babar/etc/hepix/Newuser/preferred-group $HOME/.hepix
    
If your shell has a resource dot file such as $HOME/.bashrc, add the following lines at or near the beginning:
    if [ -r /usr/local/lib/hepix/central_env.sh ]; then
      . /usr/local/lib/hepix/central_env.sh
    fi
    
If you currently call the SLAC environ script, remove it. This obsolete code may look like:
    eval `/usr/local/bin/environ /bin/ksh -i${?prompt} motif -e emacs:vi`
    
If you currently call the BABAR login scripts in your resource files or any Bourne shell equivalents you created, remove them. This obsolete code may look like the following:
    source $BFROOT/dist/releases/current/SoftRelTools/SRTstartup.sh
    
Add the following code at or near the beginning of your .profile file:
    if [ -r /usr/local/lib/hepix/central_login.sh ]; then
      . /usr/local/lib/hepix/central_login.sh
    fi
    
This completes the HEPiX setup.

Test the new setup from a separate session before you log out. If you need to back out of the changes, restore your original $HOME/.profile:

    > cd $HOME
    > cp original.cshrc .cshrc
    
Likewise restore any other changed configuration files. Once you have demonstrated that you can open a new session, exit the old session.
