Retrieve Backup in Zurich Introduction All files in the home directory in Zurich are backuped once a day and can be retrieved when something went wrong in the meantime. Retrieve the backup for Thunderbird When Thunderbird does not work anymore, the backup can be retrieved the following way:

gcc

GCC Compiler Installed Versions On lxplus, the installed version is 4.1.2, locally in Zurich, it is 4.4.1. This might make the portability of the code a bit more difficult, since the new gcc is more picky than the old one. Things You Should Think of in 4.3.2

manprompt

Get Rid of the Man Prompt When ever you use `man`, it askes which version to show. Most of the time this is annoying. To define a default version put the following code into your config files MAN_POSIXLY_CORRECT=1 export MAN_POSIXLY_CORRECT setenv MAN_POSIXLY_CORRECT 1

Monte Carlo Production in Zurich Overview At the moment Gauss, Boole, Brunel, DaVinci and Panoramix are installed in Zurich. The versions can be checked at the software page. Note that this page may not always be up-to-date. The normal chain is: Gauss -> Boole -> Brunel -> DaVinci (-> Panoramix)

python

Python startup You can configure python using a startup file. Python runs whatever file the environment variable $PYTHONSTARTUP points to. Example: History and Tab-Completion create the file .pystartup import atexit import os import readline import rlcompleter historyPath = os.path.expanduser("~/.pyhistory") readline.parse_and_bind('tab: complete') def save_history(historyPath=historyPath): import readline readline.write_history…

root_env

Zurich ROOT environment To have ROOT working on openSUSE and on the SLC5 machines, you can set something like the following lines (this is for a zsh!) in your startup files (e.g. zshrc for a zsh): if [[ -f /etc/SuSE-release ]]; then export ROOTSYS=${CERN}/root5.26.00a export PATH=${PATH}:${ROOTSYS}/bin export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${ROOTSYS}/lib fi

svncommon

Common SVN Repository Why? SVN is a very useful tool for developing code. So you should probably use it for your scripts as well. The Physics Institute has an SVN server where Roland can create a repository for you. But instead of everybody creating an own repository there is a common repository for the LHCb group. This reduces the work Roland has to do and simplifies sharing code between members of our group.

tcsh

tcsh as default shell The default shell in Zurich is zsh. Unfortunately some of the control-keys do not work in zsh on SLC5 (e.g. grid-ui). This can be fixed by using another tcsh as your shell. (If you prefer bash works as well.) Before you change your default, you probably want to test the shell. Log into grid-ui and start tcsh

vnc

To use VNC in Zurich you have to start a vncserver. vncserver -geometry 800x600 -depth 16 :1 * give it a password and look for this line in the output: Log file is read this logfile and look for the connection parameters: 11/11/2010 11:45:46 Listening for VNC connections on TCP port 5901 11/11/2010 11:45:46 Listening for HTTP connections on TCP port 5801
