Yet more things I forget

Really useful list of keyboard short cuts, most I which I routinely find myself forgetting:

http://blog.lxpages.com/2007/06/26/bash-command-line-editing/

ctrl a begining of line, ctrl e end of line, ctrl a begining of line, ctrl e end of line, ctrl a begining of line, ctrl e end of line, ctrl a begining of line, ctrl e end of line, ctrl a begining of line, ctrl e end of line, ctrl a begining of line, ctrl e end of line, ctrl a begining of line, ctrl e end of line, ctrl a begining of line, ctrl e end of line, ctrl a begining of line, ctrl e end of line

Convert from pem files to p12

Today I had to convert my grid certificate *from* the pem files to a p12/pfx file to import into the browser. Lots on google about going the other way, but not back (though I think I'm loosing my google voodoo skills...). So, for the record here's how to do it:

openssl pkcs12 -export -in usercert.pem -inkey userkey.pem -out bundle.p12

Awk the output of top to sort by memory

top -c -n1 -b|grep cmssgm|awk '{for (i=5; i<=NF; i++) {printf("%s ", $i)}printf("\n")}'|sort -n -r

JDL Attributes

A handy tutorial on writing and running grid jobs. Most useful is:

Requirements  = (!(RegExp(".*nikhef.*",other.CEId)));

Vi Search and Replace

Change to normal mode with .

Search (Wraped around at end of file):

Search STRING forward : / STRING.
Search STRING backward: ? STRING.

Repeat search: n
Repeat search in opposite direction: N (SHIFT-n)


Replace: Same as with sed, Replace OLD with NEW:


First occurrence on current line: :s/OLD/NEW

Globally (all) on current line: :s/OLD/NEW/g

Between two lines #,#: :#,#s/OLD/NEW/g

Every occurrence in file: :%s/OLD/NEW/g

ls to twiki text

The following is useful when writing twiki documentation on a load of files in a directory:

ls ../PHEDEX/Toolkit/Transfer/|awk '{for (i = 1; i <= 1; i++) print "---++ " $i}'

It will print each file in the directory as a heading for the twiki page. Change as appropriate, for example:

ls ../PHEDEX/Toolkit/Transfer/|awk '{for (i = 1; i <= 1; i++) print " i " $i}'
ls ../PHEDEX/Toolkit/Transfer/|awk '{for (i = 1; i <= 1; i++) print " * " $i}'


makes lists.

Processes run by me and their command line that called them

ps -U `whoami` -O command

Delete files from CASTOR

castordelpath = /castor/ads.rl.ac.uk/prod/cms/store/LoadTest07
for i in `nsls $castordelpath`;
do srm-advisory-delete srm://ralsrmf.rl.ac.uk:8443/srm/managerv1?SFN=$castordelpath/$i;
stager_rm -M $castordelpath/$i;
nsrm $castordelpath/$i;
done

FTS commands

Increase number of files on a channel:

glite-transfer-channel-set -s https://lcgfts.gridpp.rl.ac.uk:8443/glite-data-transfer-fts/services/ChannelManagement -f 15 T2ESTONIA-RALLCG2

List details of a channel:

glite-transfer-channel-list -s https://lcgfts.gridpp.rl.ac.uk:8443/glite-data-transfer-fts/services/ChannelManagement T2ESTONIA-RALLCG2

It's been a while...

In the process of doing some thesis corrections I've written a python parser for Les Houche events (more in another post). Anyway it's a nice little utility that writes events into an SQLite database and then make plots using matplotlib. You run it in two ways, first to read the lhe file and then secondly to make the plot.

I've found that the following bash commands are useful when working with the output from Madgraph.

Unzip the unweighted event file for each process:

• for i in `ls ~/corrections/MadGraph|grep -v tar`; do j=`ls $i/Events/|grep lhe|grep -v gz`; gzip ~/corrections/MadGraph/$i/Events/$j; j=`ls $i/Events/|grep unweighted`; gunzip ~/corrections/MadGraph/$i/Events/$j; done

Run the python parser on the unweighted file:

• for j in `ls ~/corrections/MadGraph/|grep -v gz`; do python LHEParser.py -f `ls ~/corrections/MadGraph/$j/Events/*.lhe` -d sqlite:////Users/metson/Desktop/$j.db; done; python LHEParser.py -f `ls ~/corrections/Pythia/*.lhe` -d sqlite:////Users/metson/Desktop/Signal.db;

If you delete the text file you may want to skim the output of the parser:

• for i in `ls ~/Desktop|grep -e "D.db"`; do python LHEParser.py -d sqlite:////Users/metson/Desktop/$i -s; done

Make the plots:

• python LHEPlotter.py -d ~/Desktop/
