Replace first match of $substring with $replacement .

${string//substring/replacement}

Replace all matches of $substring with $replacement .

${string/#substring/replacement}

If $substring matches front end of $string , substitute $replacement for $substring .

${string/%substring/replacement}

If $substring matches back end of $string , substitute $replacement for $substring .

ROOT lib:

Access data:

rfdir /castor/cern.ch/user/h/heli

rfmkdir ...

rfcp ..

TFile *f = TFile::Open("rfio:/castor/cern.ch/user/initial/username/myFile.root")

add the following to the
.cfg file
source = PoolSource{ untracked vstring fileNames = {'rfio:/castor/cern.ch/user/initial/username/inputFile.root'} }

and the CASTOR web page for further information.

Batch @ CERN: CAF:

You submit the job in the same way as that for smaller jobs.

bsub -q 1nd -J job1 < runMyjob.(c)sh

It is also possible to request a minimum amount of space in /pool/lsf/username/jobnumber using the -R option, for example to request a minimum of 30GB type

bsub -R "pool>30000" -q 1nd -J job1 < runMyjob.(c)sh

See the lxbatch introduction pages:

http://batch.web.cern.ch/batch/doc/quick-intro.html

Instructions on how to create a user code area can be found here UserCode/README :

http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/UserCode/README?view=log

setup CVS separately:

export CVSROOT=:gserver:cmssw.cvs.cern.ch:/local/reps/CMSSW

cvs co -r HEAD PhysicsTools/PatAlgos

cvs co -r V08-07-39 PhysicsTools/PatAlgos

You can also do

addpkg PhysicsTools/PatAlgos HEAD

addpkg PhysicsTools/PatAlgos V08-07-39

If you want to query later which version you of a package you have checked out, do, for example:

addpkg -q PhysicsTools/PatAlgos

If you want to see the version of all the packages you have in your CMSSW_4_4_4/src directory, do

showtags -q

Resume broken transfer, rsync

rsync -vP /data/ilcwork.tar heli@lxplus5NOSPAMPLEASE.cern.ch:/afs/cern.ch/work/h/heli/private/old/ilcwork.tar

VirtualBox

1. network, add host-only adapter

1.1. On virtual machine

/etc/sysconfig/network-scripts/ifcfg-eth1 with the following:

DEVICE=eth1
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.56.101
NETMASK=255.255.255.0
HWADDR=08:00:27:e0:7f:d4

/etc/hosts , add

192.168.56.101 slc5

1.2. on host, add

/etc/hosts :

192.168.56.101 slc5

2. Enable share folder with soft link:

VBoxManage setextradata SLC5 VBoxInternal2/SharedFoldersEnableSymlinksCreate/data 1

VBoxManage getextradata SLC5 enumerate

using "root",

ln -s /media/sf_data /data

add heli to vboxsf group:

/usr/sbin/usermod -a -G vboxsf heli

3. Install Virtual box addon
