If our script must be launched with witr user :

if [ $USER != witr ] ; then   echo "must connect as witr" ; exit ; fi

We have 10 projects checked out from svn repo:
/workspace/proj1
/workspace/proj2
/workspace/proj3
… etc

get last 10 log of several svn projects with shell comand line :

ls -1 | while read proj; do echo "============$proj"; svn log -l 10 $proj; done

Interactive Ruby helps you to make complex computations without having to write a whole program.
Under linux type irb.

Ex1. calculate (10-7+500)*(4 power 3 )-square root of(900)

irb(main):001:0> (10-7+500)*(4**3)-Math.sqrt(900)
=> 32162.0

Ex2. get exact date at 14 days before now (in seconds 14x24x60x60 before now)

irb(main):002:0> Time.new – (14*24*60*60)
=> Thu Nov 21 15:52:53 +0100 2013
