You can just copy paste or you can run this in shell script. You just need to change var with your script name.
Below code just prints the kill command. it won't execute it.. You can use exec for executing this command..
Code:
var="jumper_2.sh" 
$ ps -ef | awk -v VD=$var '/VD/{print $2 }' 
6361 
$ echo "kill  `ps -ef | awk -v VD=$var '/VD/{print $2 }'`" 
kill  6361

Tell me what exactly you want to do....

Please don't suggest/use unreliable grep or awk based solutions. Most if not all current Unix / Unix like distributions should provide pgrep and pkill which are much simpler to use and do not exhibit the issues of the former scripts.

..... which is unreliable.

The main issues are:

  • They are unnecessarily complex to properly implement
  • Scripts based on grep will often try to kill themselves too, which might pose serious problems depending on the timing.
  • As they are looking to the whole ps output line, they will be quite destructive when provided a pattern that match something else in that line, especially a username, a tty or just a numeric value.
