Frequently Asked Questions about the Simplified HEPiX scripts¶
In October 2011, the Linux Certification Committee agreed to a proposal to simplify the HEPix scripts for SLC6. These simplifications are implemented in version 4 of these scripts.
This page describes the main user-visible changes, and gives suggestions for end-users who miss certain functionalities. These suggestions could be implemented in the user's dot-files, or in the group-specific scripts under /afs/cern.ch/group/XX.
Your feedback is welcome at Linux.Support@cern.ch.
How to switch off HEPiX scripts altogether?¶
An "off-button" exists already in version 3 of the scripts. To completely disable the HEPiX script, simply run:
mkdir $HOME/.hepix
touch $HOME/.hepix/off
What variables have disappeared?¶
CERNLIB¶
Bourne-shell family:
CERN=/cern
CERN_LEVEL=pro
CERN_ROOT=$CERN/$CERN_LEVEL
C-shell family:
setenv CERN /cern
setenv CERN_LEVEL pro
setenv CERN_ROOT $CERN/$CERN_LEVEL
Miscellaneous¶
Bourne-shell family:
EDITOR="nano -w"
VISUAL=$EDITOR
PAGER=less
OS=Linux
ENVIRONMENT
C-shell family:
setenv EDITOR "nano -w"
setenv VISUAL "$EDITOR"
setenv PAGER less
setenv OS Linux

What aliases have disappeared?¶
h¶
Bourne-shell family:
alias h="history"
C-shell family:

C-shell family:
alias lf "/bin/ls -CF "
What about the shell prompt?¶
For tcsh users:
set prompt='%S[%m]%s %~ %#
What about the Oracle environment?¶
Users who used to rely on the $HOME/.hepix/oracle file to set up Oracle-related variables can set them in the following way:
Bourne-shell family:
ORACLE_CERN=/afs/cern.ch/project/oracle
export ORACLE_CERN
source $ORACLE_CERN/script/profile_oracle.sh
C-shell family:
setenv ORACLE_CERN /afs/cern.ch/project/oracle
source $ORACLE_CERN/script/cshrc_oracle.csh
What about the HEPiX scripts on SLC5?¶
There are currently no plans to simplify the HEPiX scripts for SLC5.
