If you execute your script in the background (with &), know that the PID of the last executed background process is saved in $!. Thus do kill $!.

Otherwise, know that whenever you execute a script--an executable file that begins with #!--the operating script automatically converts the command to the form Thus if you have an executable file called myscript, with contents and you execute it by its name from the command prompt

> ./myscript

rather than passing the script name as an argument to the interpreter

> bash myscript

when the operating system spots that the file is a script--beginning with #!--it converts the command to the form "/bin/bash ./myscript". Some versions of ps--not all of them--will print the process's command name as "interpreter" (here "bash"), rather than as the script name. This is why you are seeing -sh as the command name of the process--does your script start with #!/bin/sh?
To get around this, try format options of ps, with the -o switch. Try ps -o pid,args. This should list your processes with two columns: the first the PID of each process; and the second the complete command with which that process was invoked, which for scripts wil be of the form "interrpeter scriptname". So you should be able to search for the name of your script in the output of ps, like with grep or awk. Try: this will save the PID of the your script in $pid. To kill this process, kill $pid.

Thank you
i am not using #!bin/bash
and i am executing withhout ./
I am executing directly by typing scriptname.sh from prompt.
ps -o does not work on my system

how to get the get pid from scriptname?any other ways?
thanks
martin

if you run your script as
sh <script file>
you can do ps-ef| grep <script file>


alternatively do ps -ef | grep `echo `tty`` this will give you all the processes for the session and selectively kill -ksh sessions

i am also trying to do the same thing and caught in the scriptname.... i am not able to see it

sorry i ll follow the common forum

I Got A Lot Info From This Disscussion.
I Created A File The Existing File And Passed The Pid Of The Script Pid.
From A Different Script I Read It And Killed
