You cannot schedule a every-second cronjob. Because in cron
the minimum unit you can specify is minute. In a typical
scenario, there is no reason for most of us to run any job
every second in the system

feature which is not relavant
Cron job wakes up every minute and checks if there exists
any process in cron that requires to be executed , If yes
it executes the job and sleep again to wake up in the next
minute

Answer / santosh sathe
The only possible option is to write a script to execute
after every second in a minute.
cron will execute the script after every minute and the
script will start to execute the same after every second.
